Compact Fluorescent Lamps (CFLs) are
a single capped fluorescent lamp and
work much like a standard fluorescent
lamp. They consist of a short glass tube
or globe filled with a gas that produces
light when high voltage electricity from a
ballast flows through it. The ballast may be
either magnetic (in which case a starter is
required) or electronic. When the ballast
is permanently attached to the tube, it is
known as a self-ballasted or integral CFL
and is a direct replacement for standard
incandescent lamps. Two-part CFLs have
two or four pins on the bottom that plug into
a socket on the ballast; thus the lamp can
be replaced without replacing the ballast,
which generally has a life expectancy five
times longer than the lamps.
The international market for CFLs has
expanded rapidly in recent years. It is
now estimated that global sales of self-
ballasted CFLs will reach 550 million units in
2005, responsible for 12 TWh of electricity
consumption worldwide. Based on existing
growth rates, these figures will nearly double
by the year 2012.
Here in Australia the situation is similar, with
sales of CFLs doubling since 1999 to over
13.5 million in 2004. At the same time the
average imported cost of CFLs has dropped
to around $1.80 per unit in 2004 from a high
of $3.20 in 2000.
While the distribution of CFL sources has
been evenly spread over a wide variety of
countries up to 1995, since 1999 China has
emerged as the major countries of origin
supplying over 60% of the Australian market.
Self-ballasted CFLs provide a good energy
efficiency solution for the replacement
of general service incandescent lamps,
particularly as CFLs become cheaper.
However, moves by governments, utilities
and energy efficiency agencies to encourage
consumers to replace incandescent lamps
with CFLs are hampered by issues of
product quality. In particular it appears
some consumer expectations are not met,
particularly in respect to claims regarding
lamp lifetimes. The danger is that once
consumer confidence has been damaged, it
will be extremely difficult to re-build, and this
will have serious impacts on the potential
to decrease energy consumption from the
lighting sector.
Price alone appears no indicator of quality,
therefore Australian consumers currently
have no means to easily distinguish between
the performances of competing products.
Significantly, there is also reluctance on the
part of those agencies in Australia which
might actively encourage the use of CFLs to
do so without the knowledge that they are
supporting better performing products.

This issue has been addressed in
several overseas countries through the
implementation of endorsement programs
specifying the performance standards
for the key criteria determining quality
products. There are currently at least 12
national or regional endorsement programs
for CFLs around the world. In addition,
MEPS programs prohibiting the sale of low
efficiency CFLs have been implemented in
China, Mexico, South Korea and Japan.
As a result, NAEEEC believes that
Australia should adopt both MEPS and an
endorsement label, which is supported by
Lighting Council Australia in the ten year
strategy for efficient lighting, “Greenlight
Australia”. NAEEEC proposes to specify
standards for a number of key performance
criteria in addition to energy efficiency,
focusing initially on self-ballasted CFLs.

INTERNATIONAL HARMONISATION
The Australian Government has a policy
of matching world’s best practice, where
feasible. For self-ballasted CFLs the most
stringent MEPS and endorsement label
energy performance levels are those used
in China, although other programs have
more stringent levels for other criteria.
China is also the source of the majority
of CFLs sold in Australia, so harmonising
with the Chinese programs would mean
that lamps could be tested at source
in China to determine their eligibility in
Australia. This would reduce the testing
requirements on Australian suppliers and
the enforcement burden on Australian
regulators. Therefore matching the
Chinese performance levels is a logical
choice for the Australian programs.
While this is the best option currently,

harmonise test and performance
standards may require some fine-tuning of
the Australian proposals so that we align.
This process will be launched at a special
session hosted by Australia at the Right
Lights 6 Conference in Shanghai in May
2005. It is envisaged that if supported
by sufficient countries, harmonisation
will be achieved over the following three
years. Full international harmonisation will
substantially enhance the performance
of CFLs everywhere, and support the
initiatives undertaken in each individual
country, including Australia. The timing
is such that there is no need to delay
proceeding with Australia’s plans in order
to ensure that we are part of this global
initiative.
NAEEEC PLAN
NAEEEC proposes to introduce efficiency
regulations for compact fluorescent lamps,
with key components as follows:
1) MEPS and an endorsement label
for self-ballasted CFLs based
on the existing Australian test
method “AS/NZS 60969 (2001):
Self ballasted lamps for general
lighting services – Performance
requirements”;
2) Performance levels will be aligned
with China (see below), on the
understanding that these may
change during time taken to
develop the Australian program;
3) Industry will be advised that
the levels selected for the
endorsement label are likely to be
adopted as future MEPS levels
3-4 years after the implementation
of the first MEPS;
4) The international harmonisation of
test and performance standards
will be pursued at the Right Light
6 conference in Shanghai in May
2005, and further if supported
by sufficient numbers of other
countries;
5) Market research will be
undertaken on consumer
expectations and experiences
with respect to CFLs (the AGO
has commissioned a study to be
undertaken in March/April 2005);
6) Industry and other stakeholders
will be consulted, including
the US EPA, on whether the
endorsement label used should
be either Energy Star, TESAW or
some other option such as ELI;
7) Consideration will be given to
the introduction of MEPs and an
endorsement label for pin-type
CFLs within 3 years;
8) Detailed recommendations for
specifications are shown below.

MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 1
1. Purpose
This paper examines whether Australian Governments should proceed with the use of MEPS and/or
an endorsement label for compact fluorescent lamps (CFLs) in the Australian market, and if so, what
criteria this label should be based upon.
In this report, a number of overseas endorsement programs for CFLs are examined and their scope
and requirements are compared.
2. Background
CFLs have been available for over 20 years, and actively promoted as an energy saving device in
residential and commercial applications. During this period they have experienced several changes in
technology and design to make them more appealing and easy to use, particularly as a replacement
for standard incandescent lamps in conventional light fittings. At the present time CFLs are available in
a wider variety of styles, at a lower cost and in more outlets than ever before.
2.1. Product Description
CFLs are a single capped fluorescent lamp and work much like a standard fluorescent lamp. They
consist of a short glass tube or globe filled with a gas that produces light when high voltage electricity
from a ballast flows through it. The ballast may be either magnetic (in which case a starter is required)
or electronic. When the ballast is permanently attached to the tube, it is known as a self-ballasted or
integral CFL and is a direct replacement for standard incandescent lamps. Two-part CFLs have two or
four pins on the bottom that plug into a socket on the ballast; thus the lamp can be replaced without
replacing the ballast, which generally has a life expectancy five times longer than the lamps.
Figure 1: Components of compact fluorescent lamps
2.2. Ballasts
Magnetic ballasts have been around the longest, employing a wire-wound core to limit current drawn
by the lamp. These ballasts typically consume an additional 15% to 25% of the lamp wattage,
producing heat as a by-product. More energy-efficient magnetic ballasts have been developed
recently using improved materials and manufacturing processes, but they tend to be slightly larger and
more expensive than standard ballasts.
Most magnetic ballasts deliver current to the CFL at the same frequency supplied by the utility. The
most recently developed ballasts are the smaller, lighter and more energy-efficient high-frequency
electronic ballasts. These ballasts use transistors or thyristors to boost the input power to a frequency
range of 25 to 40 kHz. High-frequency operation offers the advantages of improved overall efficiency,
improved efficacy, reduced hum and increased lamp life. On the other hand, such ballasts are more
likely to cause electromagnetic interference and are more susceptible to damage from supply voltage
spikes and other transients. However many new electronic ballasts now come with built-in filtering and
protection circuits to reduce or eliminate problems of this kind.
Components of a typical compact
fluorescent lamp. A compact
fluorescent lamp consists of a gas-
filled glass tube with two electrodes
mounted in an end cap. It contains
a low-pressure mix of argon gas,
mercury vapor, and liquid mercury,
and is coated on the inside with
three different phosphors. The
electrodes provide a stream of
electrons to the lamp and the
ballast controls the current and
voltage flowing into the assembly.
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 2
2.3. Colour
The first fluorescent lighting systems used a single phosphor coating inside the lamp and produced a
cool white light. With the development of more efficient ’tri-phosphor‘ coatings came smaller ’compact
fluorescent‘ lamps with light outputs rivaling those of incandescent lamps of similar size. The three
phosphors produce light in the red, blue and green regions of the visible spectrum, giving white light
when blended together. By changing the relative balance of these phosphors, manufacturers can
produce CF lamps in a range of apparent colour temperatures from a cool 4100K (degrees Kelvin) to a
warm 2700K. Incandescent lamps have a colour temperature of about 2900K.
The Colour Rendering Index (CRI) of a lamp reflects how accurately the colour of an object can be
determined under a given light source. Compact fluorescent lamps typically have a CRI of 82 (out of
100), which is considered excellent for fluorescent sources and good for artificial light in general.
Incandescent lamps have a CRI of 97. Incandescent lamps provide excellent colour rendering
because of the full spectrum of colour wavelengths present in the light they produce.
2.4. Market Issues
The international market for CFLs has expanded rapidly in recent years. For example, in the United
States from 1998-2000, CFLs had a consistent 0.5% national market share. In California, this figure
was 1%-1.6%. In 2001, the market share nationally grew to 2.2%, while in California the state market
share became 8%.
It is now estimated that global sales of self-ballasted CFLs will reach 550 million units in 2005,
responsible for 12 TWh of electricity consumption worldwide(MEA 2005). Based on existing growth
rates, these figures will nearly double by the year 2012 (see Figure 2).

World CFL Sales
Total Energy Consumption
Over the last two to three years, the retail price of CFLs has dropped considerably, both overseas and
in Australia, and the range of lamps available has also increased dramtically.
In the United States, despite a fall in lamp prices from $25/unit in 1998 to $5 in 2001, for the first time
the total value of CFL sales in 2001 matched that of incandescent lamps (Calwell et al 2002).
An indication of the growth in product range is shown by the number of Energy Star partners. By the
beginning of 2001, Energy Star partners included 17 manufacturers and covered 161 products. By the
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 3
end of 2001, partners comprised 94 manufacturers covering 455 products (Calwell et al 2002), and the
number of active partners has now increased to 147 (Karney 2004).
While less dramatic, branded CFLs in the UK have also experienced reductions in price, falling by half
over the two years prior to 2001. As in the US, the value of CFL sales now equals that of standard
GLS lamps (ECI 2001).
Here in Australia the situation is similar, with sales of CFLs doubling since 1999 to over 13.5 million in
2004 (see Figure 3). At the same time the average imported cost of CFLs has dropped to around
$1.80 in 2004 from a high of $3.20 in 2000 (ABS 2004/5).
Figure 4 shows the country of origin for CFL imports from 1995 to 2004. While the distribution of CFL
sources was evenly spread over a wide variety of countries in 1995, since 1999, China and Germany
have emerged as the major countries of origin. Together they provide over 90% of all CFLs entering
the Australian market in 2003 (ABS 2004/5).

A recent survey of products available at Bunnings, the hardware chain, showed that there were 42
CFL models on sale, supplied by three manufacturers (MEA 2004). Of these 7 were pin-type.
Prices ranged from $6.20 to $29.94, with the average price being $10.50. The distribution of prices is
shown in Figure 5, demonstrating that nearly 90% of models are below $15 each. This is nearly half
the average price of a sample tested by Choice Magazine in 1999/2000, when the average was found
to be $20.30 (Choice 2001).

The increasing use of CFLs, and to some extent the intense price competition, has brought issues of
product quality to the fore. Product performance has always been an issue, however the sheer
numbers involved now make this appear of greater significance. There is also a suspicion that in an
effort to reduce prices, there may be some slippage in performance levels.
Although it is hard to quantify, some consumers in many countries have expressed their dissatisfaction
with CFLs, particularly with respect to the advertised service life and light output. In an effort to
increase consumer confidence by identifying the better performing models, several countries have
adopted energy endorsement labels.
3. Key Issues
It may be intuitive to assume that the presence of CFLs with a variety of performance characteristics
and price points will, or may eventually lead to reduced consumer confidence in CFLs. However, the
issue of whether an endorsement label for CFLs is warranted involves answering a number of
questions in relation to consumer sentiment and the performance of CFLs. These are summarised as
follows:
- Are there consumer expectations particularly associated with CFLs? If so what are these?
- Is there evidence of consumer dissatisfaction? Might there be dissatisfaction in the future?
- To what extent is there a basis for consumer complaints?
- Are there any further reasons for using an energy label?
These issues are discussed further in this section.
3.1. Consumer Expectations of CFL Performance
CFLs are marketed to consumers on the basis of their performance relative to ‘standard’ lamp types,
such as GLS. Typically CFLs are promoted as having a lower energy consumption and longer life than
their incandescent equivalents. Figures are often provided in marketing materials, including CFL
packaging, to demonstrate the cost effectiveness of CFLs over the lifetime of the lamp, and to justify
the extra capital investment. These calculations of the ‘payback’ time are predicated on assumptions
regarding the lamp lifetime, and claims of equivalent light output compared to ‘standard’ lamp types.
Such has been the use of this type of information by the industry and other agencies seeking to
promote CFL lamps, that it is likely that many consumers who purchase a CFL will have some
expectation that CFLs last longer, and that their light output is similar to the wattage of GLS lamps
identified on the packaging. Indeed, CFLs are quite often referred to as ‘long-life lamps’.

3.2. To what extent are consumers dissatisfied with the performance of CFLs?
While there is no known data collected on the numbers of disaffected consumers, the anecdotal
evidence is there. The Australian Consumer Association, the AGO and other energy efficiency
agencies in Australia have received complaints and queries relating to the premature failure of CFLs,
and those in the industry cite many further instances.
This is by no means an Australian phenomenon, since endorsement labelling programs implemented
in several overseas countries are designed to address exactly this issue. Correspondence with China
and the UK indicate that their endorsement labelling programs were initiated as a direct result of
consumer complaints. These programs are discussed in the following section.
However, despite this anecdotal evidence we have not been able to find any consumer surveys
designed to determine the degree to which purchasers may be dissatisfied. However in a report on
CFL promotions in the UK, the following comment is made:
“There is as yet no evidence (other than anecdotal) that shorter-lifetime CFLs have damaged
the market. Evidence from New Perspectives (2000) showed both that people do not
understand how long a CFL should be lasting, and that most felt that if a lamp lasted 2 years
they would be satisfied. This may indicate that despite the concerns of the industry, shorter
lifetime products will not have a negative effect on consumer perception.” (ECI 2001)
It should be noted that this conclusion is quite heroic, given that this was not tested by the survey,
however it is probably true that consumer expectations on lifetimes reflect the capital cost of CFLs. In
an environment of falling prices it may be that consumers do not expect them to last so long (New
Perspectives 2003).
Before proceeding, it may be worth undertaking some surveys, perhaps by telephone, to test the
extent of any dissatisfaction in Australia.
Of course, even if there was evidence that consumers were generally satisfied about the performance
of their CFLs now, this would not guarantee that they would continue to be in the future. If prices
continue to drop and result in lower performance standards, then consumer dissatisfaction might be
expected to grow.
The key issue is therefore whether it is worth taking the risk, given that it is always harder to rebuild a
reputation than to maintain it.
3.3. Is there any justification for consumer complaints?
We have assumed that the major consumer expectation is of increased lamp life, based on the life
shown on the packaging. The ‘average’ lamp life contained in most standards is taken to be the length
of time before 50% of a sample of lamps fail under test conditions, where the sample of lamps is
greater than 20. The details of various standards and endorsement criteria are discussed further in
later sections, however this is a typical definition.
This in itself may surprise many consumers: that the lifetime quoted is only an average and that half of
the lamps may fail by this time, and many may fail well before then while still being considered valid.
Even within this definition, surveys show that some lamps on the market do not fulfil this requirement.
A set of tests on 23 commonly available CFL models (undertaken by Choice Magazine for the
Australian Greenhouse Office in 1999/2000) found that 5 (22%) had more than a 50% failure rate at
the quoted average life. In 4 of these models, all the sample products tested failed to meet the
average life. An additional 2 had a 50% failure rate. These tests were undertaken on 10 samples per
model (Choice 2001).
The results of the Choice Magazine tests are plotted in Figure 6. This shows the proportion of samples
for each lamp type which failed at the rated lamp life (X-axis) against the cost of each lamp type. This
indicates that:
- for lamps to the right of the dotted line, more than 50% of the sample failed before by the rated
lamp life, and
- there is no correlation between longevity and the price of the product.

The results of this test by Choice Magazine is very similar to those from a test undertaken by the UK
Lighting Association on behalf of the Department for Environment Food and Rural Affairs (Defra). This
found that 4 out of 12 models tested failed to achieve their claimed average life, for a sample of 20
products per model. (MTP 2000). In a further part of this survey, it was found that 5 out of 12 models
were labeled with the incorrect (A-G) class, as required by EU labelling regulations.
Although these studies involve a small sample and occurred a few years ago, it appears likely that at
least some lamps do not live up to the claims made.
3.4. Are there other reasons for using an endorsement label?
There are at least two further reasons why an endorsement label may also be warranted.
Given the concerns about the performance of some CFLs, there may be an increasing reticence
amongst third parties to promote the use of CFLs. Currently there are a wide range of organisations
which encourage the uptake of CFLs, including energy efficiency agencies, governments and NGOs,
and these greatly enhance the marketing efforts by industry. In addition, State-based energy efficiency
agencies and some utilities have initiated financial incentives for CFLs. If these third parties fear that
the products they promote do not meet expectations, they are likely to withdraw support rather than
risk their own credibility amongst customers.
In addition, there is a possibility that the market share of premium products becomes eroded by
cheaper and shorter life products. For example there has recently been an influx of 3,000 hour
products. If this trend continues then longer life CFLs may get withdrawn entirely from the market. This
is of concern since there is no certainty that self-ballasted CFLs will get replaced with another CFL at
the end of its life – hence energy savings can only be assured for the life of each lamp. We could
therefore see consumers reverting to incandescent lamps after a relatively short period.
4. Existing Regulatory Position in Australia
CFL lamps are a ‘prescribed’ product in Australia and therefore are required to meet relevant safety
standards. They do not however have to meet performance standards. The following section identifies
relevant Australian and International standards applying to CFLs, highlighting the key elements of test
methodologies and performance requirements. The voluntary lamp labelling program initiated by the
AGO is also described.
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 8
4.1. Standards
The three primary standards relating to CFLs are:
- AS/NZS 60969 (2001): Self ballasted lamps for general lighting services – Performance
requirements.
- AS/NZS 60901 (2003): Single capped fluorescent lamps – Performance specifications. This
covers all single-capped fluorescent lamps with an external ballast (ie. pin-type).
- AS/NZS 4783.2 (2002): Performance of electrical lighting equipment – Part 2 : Energy labelling

4.5. Labelling
The Australian Greenhouse Office has initiated a voluntary labelling program for domestic lamps sold
in Australia
1
. The labelling requirements are identical to those established in 1998 by the European
Union (98/11/EC) (see Appendix 1) and are contained within Appendix B of the Australian Standard
4782.2:2004. The label is a comparative energy label, ranking lamp performance in terms of energy
efficiency on an ‘A-G’ scale (see Figure 7).
Figure 7: Bands for the European Energy Label (‘A-G’)

At this stage, use of the label is not mandatory, however state governments will consider a mandatory approach should the
proportion of household lamps that carry the label not increase substantially.

Note: the ‘G’ category includes all lamps falling in the area above the ‘F’ category.
In addition to energy performance, the label must carry information on the following attributes for each
lamp:
- The luminous flux of the lamp in lumens.
- The input power (wattage) of the lamp.
- The average rated life of the lamp in hours. Where no other information on the life of the lamp is
included on the packaging, this may be omitted.
Many domestic lamps currently sold in Australia already carry this label, shown in Figure 8 below.
Figure 8: Comparative Label: European ’A-G’
The primary aim of this label is to demonstrate to consumers the benefits of switching from
incandescent bulbs (such as GLS) to CFL type bulbs. Since the ‘A-G’ rating label only ranks lamps
according to their efficiency, the label effectively differentiates between different types of lamp
technology. The following figure shows the approximate distribution of lamp technologies according to
the ‘A-G’ label.
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 11

A - tri-phosphor fluorescent lights (linear strips and pin-based CFLs) and integral electronic ballast CFLs
B - halo-phosphor fluorescent lights (linear strips and pin-based CFLs) and integral magnetic ballast CFLs
C - efficient halogen bulbs

E/F - standard GLS bulbs

Table 2 shows the relevant European Label for a range of common lamps types produced for the
domestic market in Australia by Sylvania (Sylvania 2003). This is typical of the range of products
provided by major lamp manufacturers/importers, and indicates that all CFLs are rated as either ‘A’ or
‘B’, while incandescents are rated from ’D’ to ‘F’.

While the ‘A-G’ label provides consumers with a good indication of the comparative efficacy of
different lamp technologies, it does not provide a good guide to the comparative performance of
different lamps of the same technology. The major reason for this is that the range of efficiencies
represented by each band is relatively large, and also that efficiency is only one performance measure
valued by customers in relation to lamps in general and CFLs in particular. Other factors such as lamp
life and lumen maintenance amongst others, affect consumer choice and are the basis for their
expectations.
5. The Role of Minimum Energy Performance Standards (MEPS) & Labelling
Programs
The following section briefly describes the role of MEPS and different types of labeling programs
typically used to promote energy efficiency.
5.1. Minimum Energy Performance Standards (MEPS)
MEPS are mandatory standards applying to many products sold in Australia, set at a level to prohibit
sale of the worst performing products in the marketplace. They currently apply to a range of residential
appliances in Australia and are soon to be introduced for fluorescent lamps and commercial
refrigerators, amongst other equipment.
MEPS are not designed to promote the best performing products, but can be combined with policy
measures that do have this aim such as labels. However, the standard for commercial refrigerators
also specifies a ‘high efficiency level’ which requires that only products which meet this performance
level can use this term for marketing purposes. Although manufacturers are free to choose whether
they sell a product within this category, the aim of this standard is to protect the investment of those
who produce products which meet this superior level of performance.
5.2. Labelling
In general, labels attempt to provide consumers with information at the point of purchase. To be
effective they rely upon consumers having a good understanding of what the label represents, and on
the likelihood that consumer purchasing decisions will be altered by knowledge of the energy
performance of the particular product. Energy labels are widely used in Australia (since 1987) and
there is a high degree of consumer recognition of the energy star rating label used on whitegoods and
other appliances.
5.3. Endorsement Label
An energy endorsement label is used to signal to consumers that a product
meets particular criteria (typically but not always related to performance). It
provides an easily recognizable indicator so that consumers can identify
‘conforming’ products without having knowledge of detailed performance
characteristics.
To work effectively, consumers must recognise the label and what it represents, at least at some
rudimentary level. They must regard the qualities indicated by the endorsement label as valuable and
credible. Government-backed endorsement labels are therefore generally more effective since
consumers tend to regard governments as impartial authorities.
The most familiar energy endorsement label is ‘Energy Star’ – the logo developed by the US
Environment Protection Agency (EPA). This is now used worldwide on a variety of electric and
electronic consumer items. Like any endorsement label, Energy Star is primarily a marketing tool
enabling manufacturers to easily promote the best products to their customers.
5.4. Comparative Label
A mandatory energy label is applied to a growing range of appliances in
Australia. which uses a star rating scale to compare the performance of
different models. The number of stars allocated to a model is calculated
using a formula given in the relevant Australian Standard. The label also
carries an estimate of the annual energy consumption of the appliance
based on the tested energy consumption, and information about the typical
use of the appliance in the home. The actual performance data and typical
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 13
running costs for each model are also available in publications and on a website.
Comparative labels work best when models in the marketplace exhibit a spread of performances,
thereby providing a range of ratings for consumers to choose from.
5.5. Warning Label
A ’warning label‘ is similar to an endorsement label except that its aim is to highlight poorly performing
products. The intention is that manufacturers will avoid having to use the warning label by improving
the performance of their products. Clearly, if a product qualifies for the label it must be a mandatory
requirement that the label is fixed to the relevant product. To date, the warning label has not been
used in Australia.
6. Overseas CFL MEPS Programs
MEPS programs prohibiting the sale of low efficiency CFLs have been implemented in China, Mexico
and South Korea. China and South Korea have integrated MEPS with a labelling program for CFLs.
Japan has also established weighted average efficiency targets for lighting appliances using CFLs in
its Top Runner Program. This approach differs from MEPS in that it does not prevent products which
do not meet the standard from being sold. Rather, it requires the average efficiency of products
shipped by a manufacturer or importer in a target year to meet set efficiency levels.
A summary of the scope of these programs is shown in Table 3. Details of the MEPS levels and
testing methods for each program are given in Appendix 2.

Each country specifies MEPS for efficiency in terms of Lumens per Watt for various types of CFLs at
different wattages. Figure 10 compares the MEPS levels between China, Mexico and South Korea for
self-ballasted CFLs. Figure 11 shows the Chinese MEPS levels for pin-type CFLs.

7. Overseas CFL Labelling Programs
Programs designed to differentiate between the performances of CFLs have been implemented in
several countries around the world. Table 4 lists the CFL endorsement labeling programs, highlighting
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 15
the scope of each. The following section and Appendix 3 provide greater detail on the certification
criteria and requirements.
It should be noted that there are two basic models for endorsement labelling programs applied to
CFLs. These are:
- Those which use the EU Labelling Directive (92/75/EEC) and Quality Charter for CFL Lamps as
their basis, and conduct most of their tests to IEC 60969 or 60901; and
- Those which use Energy Star as their basis and test to IESNA – LM66-00, IESNA – LM65 & ANSI
– C78.5.

7.1. Efficiency
There is some variation in efficiency requirements, expressed as maximum power consumption per
initial lumen output, although this is small. Figure 12 compares the thresholds for the Chinese label,
Energy Star and the European labeling program. Note that the Chinese program has different
thresholds dependent on the lamp colour temperature. Both the Chinese thresholds are more
stringent than the others, although Energy Star and the European ‘A’ class are approximately
equivalent.

MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 18
7.2. Lumen Maintenance
Although the requirements are generally similar, there are considerable differences in how the
requirements are expressed, with measurements varying between 1,000 hours (Energy Star), 2,000
hours and 40% of rated lifetime.
7.3. Lifetime
Generally all programs use the average life of a sample (typically >20) to determine the lifetime. There
are some differences in the test method with respect to the rapid cycle test and the position of the
lamp during testing.
The minimum requirements for lamp life also vary between programs. The Energy Saving Trust
program requires that not more than 10% of sample lamps fail the test at 2,000 hours, in addition to a
maximum 50% failure rate at the average life.
The requirements of each labelling program with respect to these issues is shown in Table 5.
7.4. GLS Equivalence
Not all programs include requirements for the equivalence to be tested or checked, however amongst
those that do, there is considerable consistency. Mostly this is presented as a table, however in the
case of the Energy Saving Trust, their criteria are displayed graphically.
7.5. Power Factor
Generally power factors must be 0.5 although some require 0.9 as a minimum. Some require that
lamps may only be labelled as having a high power factor if they are 0.9.
7.6. Luminous Flux Run-up
Most programs have a requirement for the time taken to reach a proportion of the final stabilised lamp
output. For example:
- To 10% of light output 2 seconds
- To 60% of light output 60 seconds
However the precise requirements do vary slightly between programs.
7.7. Environmental Requirements
Some programs go beyond energy performance to include environmental criteria such as limits on
mercury content and the use of recycled packaging materials.
7.8. Other Features
Almost all programs include similar requirements for the following attributes:
- Colour rendering
- Colour Temperature
- Electromagnetic inference – this tends to be specific to each country.

MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 20
8. Conclusions
8.1. The case for MEPS and/or an endorsement label
Although there is so far only anecdotal evidence that the reputation of CFLs has been damaged in Australia,
there seems stronger evidence that this has been the case overseas, giving rise to the implementation of
endorsement labels for higher quality products.
The prices of CFLs continue to fall in Australia, reducing the payback period and degree to which consumers
might feel cheated by lamps which fail early. Since there appears to no obvious correlation between price and
performance (particularly longevity), this leaves consumers with no means to easily distinguish between the
performances of competing products.
In view of the difficulties in re-establishing credibility once damaged, there is justification in taking a
precautionary approach, ie. acting in advance of strong evidence that consumer confidence in CFLs has been
damaged.
In addition, there has been some reluctance on the part of those agencies who might actively encourage the
use of CFLs to do so without the knowledge that they are supporting better performing products.
These arguments support the use of an endorsement label, designed to promote the better performing
products in Australia. However, there is also justification for the introduction of MEPS for CFLs to remove the
worst performing products from the market, and to ensure that these do not enter the market at some future
date.
This is endorsed by Lighting Council Australia in the ten year strategy for efficient lighting, “Greenlight
Australia” discussed below.
The use of both MEPS and a ‘high efficiency’ level signaled by an endorsement label has been used in
Australia for other products with success. Typically, the high efficiency levels serve as an indication of likely
future levels for MEPS, which are usually implemented 3-4 years after the current MEPS levels, as technology
advances. One significant advantage for manufacturers is that this provides regulatory certainty over a period
of 6-8 years, allowing them to plan ahead.
The above arguments apply primarily to self-ballasted CFLs, which account for the majority of CFLs sold in
Australia. It is hoped that in due course the number of pin-type CFLs sold will also increase, when the range
of luminaires grows, and for this reason it will be sensible to review the need for similar measures for these
CFLs within the next 3 years.
8.2. Greenlight Australia
In December 2004, Australia’s Ministerial Council on Energy approved Greenlight Australia, a strategy aimed
to reduce lighting energy consumption by 20% by 2015, from its current level of around 25 TWh of electricity
annually. Greenlight Australia has been developed jointly by Government and the Australian lighting industry
with the objective of providing a clear indication of future policy. This provides industry with adequate time to
prepare by highlighting areas for investment, thereby minimising any potentially detrimental economic
impacts.
Figure 6 outlines the projects that will commence development in the period 2005/6 to 2007/8, which includes
MEPS and an endorsement label for CFLs.

8.3. Proposed Criteria and Performance Standards for CFLs in Australia
The existing test methods for CFLs in Australia are based on IEC procedures and are suitable for testing most
of the criteria used to evaluate the performance of CFLs. An additional test method for the determination of
mercury content has been developed in association with the regulatory standards for linear fluorescent lamps
and is applicable to CFLs. This can be added as an appendix to the existing test methods.
As shown in previous sections, there are a range of criteria typically used to determine the performance of
CFLs, some of which are common to most programs currently in existence. These are important
considerations since issues such as the lamp lifetime, colour and start-up time tend to be those of greatest
concern to consumers. The major performance criteria covered by most programs, and which should be
included in the Australian program, are:
Efficiency level
Lumen maintenance
Rated average lifetime
CFL lifetime claims
Power factor
Colour rendering
Mercury level
GLS equivalence
Start-up time
Each of these criteria would have one set of performance levels for MEPs and a second set for the
endorsement label, with the latter typically being more stringent.
In terms of setting appropriate performance standards, the Australian Government has a policy of matching
world’s best practice, where feasible. For self-ballasted CFLs the most stringent MEPS and endorsement
label energy performance levels are those used in China, although other programs have more stringent levels
for other criteria.
China is also the source of the majority of CFLs sold in Australia, so harmonising with the Chinese programs
would mean that lamps could be tested at source in China to determine their eligibility in Australia. This would
reduce the testing requirements on Australian suppliers and the enforcement burden on Australian regulators.
Therefore matching the Chinese performance levels is a logical choice for the Australian programs.
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 22
While this is the best option currently, international efforts to rationalise and harmonise test and performance
standards should be monitored during the next one to two years (approximately the time taken to introduce
standards) so that Australian proposals can be fine-tuned.
The push for international harmonisation will be launched at a special session hosted by Australia at the Right
Lights 6 Conference in Shanghai in May 2005. It is envisaged that if supported by sufficient countries,
harmonisation will be achieved over the following three years. A copy of the proposal to be discussed at this
meeting is included in Appendix 4.
Full international harmonisation will substantially enhance the performance of CFLs everywhere, and support
the initiatives undertaken in each individual country, including Australia. The timing is such that there is no
need to delay proceeding with Australia’s plans in order to ensure that we are part of this global initiative.
8.4. What type of endorsement label would be suitable?
Many of the existing major CFL endorsement labels use similar scope and criteria on which to base an
Australian endorsement label. Not all programs currently include pin-type CFLs however, and since the use of
these should be encouraged, it would seem sensible for them to be included at some stage. Whether wider
environmental requirements, such as mercury content, should be included is a matter for debate and it is likely
that further discussions with industry, consumer groups and other stakeholders will be useful in order to define
the scope.
The Australian Greenhouse Office has a licensing arrangement with the US EPA covering
the use of the Energy Star program in Australia, which currently covers home
entertainment and office equipment. The Energy Star CFLs criteria are based on US test
methods which are similar but not identical to the IEC test methods, which is one reason
why no other country outside the United States has used this label. Discussion have been
underway between Energy Star and a number of countries about setting CFL criteria
suitable for a 230volt/50Hz system, and it appears that this might be possible.
Another endorsement label used in Australia is the Top Energy Saver Award
(TESAW), which is currently used to promote domestic wet goods, refrigerators and
freezers, and some air conditioners.
Both of these options appear to be suitable, however there is also discussion
regarding the use of an international symbol, such at the ELI logo, at some stage in
the future, pending decisions on further harmonisation. The use of a truly
international label, tied to an international test method and set
of criteria, would also be appropriate and should be
encouraged by Australia.
A final decision on the form of endorsement label should be made following further discussions between the
government and industry.

9. Recommendations
It is recommended that the NAEEEC undertakes the following actions:
1) Implements MEPS and an endorsement label for self-ballasted CFLs based on the existing Australian
test method “AS/NZS 60969 (2001): Self ballasted lamps for general lighting services – Performance
requirements”;
2) Proceeds on the basis that the performance levels will be aligned with China (see below), on the
understanding that these may change during time taken to develop the Australian program;
3) Indicates to industry that the levels selected for the endorsement label are likely to be adopted as
future MEPS levels 3-4 years after the implementation of the first MEPS;
4) Pursues plans for the international harmonisation of test and performance standards at the Right Light
6 conference in Shanghai in May 2005, and further if supported by sufficient numbers of other
countries;
5) Undertakes market research on consumer expectations and experiences with respect to CFLs (it is
understood that the AGO has commissioned a study to be undertaken in March/April 2005);
6) Consults with industry and other stakeholders, including the US EPA, on whether the endorsement
label used should be either Energy Star, TESAW or some other option such as ELI;
7) Considers introducing MEPs and an endorsement label for pin-type CFLs within 3 years;
8) Detailed recommendations for specifications are shown in Table 7.

Appendix 1: COMMISSION DIRECTIVE 98/11/EC of 27 January 1998 implementing
Council Directive 92/75/EEC with regard to energy labelling of household lamps
The energy efficiency class of a lamp shall be determined as follows:
Lamps shall be classified in class A if:
- Fluorescent lamps without integral ballast (those requiring a ballast and/or other control gear to connect
them to the mains)
W 0,15 \| + 0,0097|
- Other lamps
W 0,24 \| + 0,0103|
where | is the lumen output of the lamp
where W is the power input into the lamp in watts.
If a lamp is not classified in class A, a reference wattage W
R
shall be calculated as follows:
W
R
= 0,88 \| + 0,049|, when | > 34 lumens
0,2 \|, when | 34 lumens
where | is the lumen output of the lamp.
An energy efficiency index E
I
is then set as:
E
I
= W / W
R
where W is the power input into the lamp in watts.
The energy efficiency classes are then set in accordance with the following table:
Table 8: Definitions of Energy Efficiency Classes

The standard for integral CFLs (GB /T 19044—2003) and pin-type CFLs (GB 19415—2003) came into force in
June 2003, and sets two thresholds:
- Minimum Efficiency Standards – The standard that all products must achieve to go on sale;
- Certification Standards – An optional efficiency level for premium products.
Certification labelling to enable the easy identification of premium (both quality and efficiency) products by
consumers is relatively new within China. This is particularly true for lighting products for which no similar
work has taken place before; a situation that has led to a serious souring of the market for CFLs as poor
quality products have disappointed consumers who have then switched back to incandescent lamps.
Tables 9 and 10 show the MEPS and certification efficiency thresholds for integral and pin-type CFLs
respectively.

- Lumen maintenance: After 2000h testing (with 2 hours and 45 minutes on and 15 minutes off) lumen
maintenance must be 80.
The testing requirements (GB/T 17263 and GB/T 2828) are almost equivalent to IEC standards.
There are currently about 20 manufacturers who have applied for certification for CFL; and 14 have received
certification covering about 200 products. (Lui Hong 2003)
Although formal adoption of the new certification procedures is yet to occur, 20 manufacturers have already
submitted over 300 products for certification.
B. Top Runner Program (Japan)
Japan does not have MEPS. Instead, Japanese manufacturers and importers are obliged under the Law
Concerning the Rational Use of Energy (Law No.49 of 1979) to meet a weighted average target standard for
all their products in a category by a specified year (target year). That is, the average efficiency of all products
shipped by a manufacturer or importer in the target year must be above the set standard.
The standard is usually set using the most efficient product in the market as a benchmark to be reached by
the target year. If a manufacturer wishes to sell products that do not meet the standard, they must also make
products which have a much higher efficiency to adjust their weighted average to meet the target. This
average target approach encourages energy efficient products without excluding products which do not meet
the target value from the market, retains product diversity and provides flexibility to meet consumer demands.
Notification No. 191 of the Ministry of International Trade and Industry of 1999 set target levels for all
fluorescent lighting appliances to be met by during the 2005 to 2006 financial year. Table 12 sets out the
targets for lighting appliances which use CFLs. Manufacturers or importers who ship less than 30, 000 units
are exempt from the target.

Energy consumption efficiency is calculated from measurements of luminous flux and power consumption.
Details for how these are measured are given in Table 12.
The calculations are as follows:
energy consumption efficiency (lm/W) = luminous flux (lm) / power consumption (W)
luminous flux (lm) = total luminous flux (lm) x optical power coefficient of ballast x temperature
correction coefficient
optical power coefficient of ballast = optical power of ballast / optical power of reference ballast

C. MEPS in Mexico
In 1998, an Official Mexican Standard (Normas Oficiales Mexicanas or NOM) was implemented for CFLs
under the Federal Law of Metering and Standards. It is compulsory for all CFLs up to 28W to meet the
efficiency levels set out in Table 14 and for ballasts in modular systems to meet the efficiency levels in Table
15. The standard is in partial agreement with IEC 901-1987, amended in 1989 and 1992, however, the
electricity supply in Mexico is 60Hz. The method of test is detailed in Table 16.

D. MEPS and Labelling Programs in South Korea
The mandatory labelling and MEPS program for CFLs came into force in 2000 under the Law on the
Rationalized Use of Energy and is administered by the Korea Energy Management Corporation (KEMCO).
Two thresholds are defined:
- MEPS – this standard defines the lowest rating of 5 on a comparative label and all products on sale
must exceed the MEPS level in Table 17.
- Target Energy Performance Standards (TEPS) – this standard defines the top rating of 1 on a
comparative label
The labelling program compares the performance of different products to the TEPS level and assigns a rating
according to Table 18. The standard levels are revised every few years with the old TEPS level becoming the
new MEPS level.

3.A Summary of Energy Saving Trust Requirements (UK)
Since 2000, the Energy Saving Trust has maintained a web-based list of
‘Recommended’ CFLs, which are entitled to carry the energy efficiency
logo. The CFL criteria has been updated subsequently and a summary of
the key requirements are shown in Table 19 below.
The endorsement label covers both self-ballasted CFLs and pin-type
models, divided into the following categories:
Group 1: Self Ballasted
a. Integral:
- ‘S’ which meet Class A of EU Directive on energy labelling of lamps
- ‘L’ which meet Class B of EU Directive on energy labelling of lamps, but 85% of minimum
efficacy requirements
b. Two-part with electronic control gear, sold as a single entity:
- ‘T’ meeting the requirements of Group 2 below
Group 2: Pin-Type
- Lamps requiring separate electronic ballasts, provided in a suitable luminaire or adaptor
(as with ‘T’)
There are currently 104 eligible products on the UK market, equally divided between self-ballasted and pin-
based CFLs (see Table 19).

3.B Summary of Energy Star Requirements
The Energy Star program for CFLs was launched in 1999 and there are now 1,044
products meeting current requirements in the US.
In an assessment of the Energy Star program for CFLs, Calwell et al (2002)
suggest that the high growth rates achieved in the US 2001 (mentioned previously)
were a combination of a number of factors, not least a sustained focus of a number
of programs over a period of time, which had a cumulative impact on the
technology and consumers. The authors point out that the technology has evolved very quickly over the past
five years, providing many models of various shapes. While Energy Star labelling played a part in this, it was
only one element of consumer education. It is noteworthy that the aim for Energy Star over the near future is
to move away from consumer education and to focus more on refining product specifications.
The following table lists the major requirements for products that wish to qualify for the Energy Star
endorsement label from 1.1.2004.

stabilized light output after switch-on shall not exceed 120 seconds (measured in accordance with IEC
60969).
Other Performance Specifications
Comparison of CFL to
GLS on Label**
Lumen output noted on package must be the luminous flux as reported to ELI for the specific lamp and
ballast combination in the package. Where the packaging or other literature claims that the rated luminous
flux of the CFL is equivalent to, or exceeds that, of an equivalent GLS filament lamp the lamp rating must
comply with the following requirements:
CFL Luminous Flux Claim (lm) Rated Wattage of Equivalent GLS Filament Lamp
214 25 W
386 40 W
530 50 W
660 60 W
874 75 W
1100 90 W
1246 100 W
2009 150 W
In addition, manufacturers must notify ELI if the CFL exhibits 10% light output
degradation due to:
• Operation outside of rated temperature range or,
• Operation in other than VBU position or,
• Any other factors
Warranty Purchaser may return the CFL to point of purchase with no explanation necessary within 12 months from the
date of purchase for a full refund. Written warranty in at least one applicable local language must be included
with CFL when purchased. Manufacturer shall provide a local address for customer contacts and complaints.
Quality of Production CFLs must be manufactured under a Quality Assurance System in accordance with ISO 9000-2000 or
equivalent (equivalency to be determined by ELI).

3.G European Eco Label
The European Eco-label is a voluntary scheme enabling European consumers to easily
identify officially approved green products across the European Union, Norway,
Liechtenstein and Iceland. It allows producers to show and communicate to their
customers that their products respect the environment.
Environmental criteria are developed to cover everyday consumer goods and services
(with the exception of food, drink and medicines). At present, the EU flower can be
awarded to 21 product groups including CFLs.
The current CFL criteria were adopted on 1 Sept 2002 and are valid until 31 August 2005
and include the following requirements:
- Minimum lifetime: Single-ended 10,000 hours.
- Lumen maintenance:
Single-ended (self-ballasted) 70% at 10,000 hours.
Single-ended (pin based lamps) 80% at 9,000 hours.
- Switch on/off cycle > 20,000 for CFLs.
- Colour rendering (Ra) index > 80.
There is currently only one brand which complies, which is the Linea Self ballasted compact fluorescent lamp.
This CFL is available in 5W, 7W, 9W, 11W.
3.H Danish Electricity Saving Trust [Karbo 2001]
In the autumn of 2000, the Danish Electricity Saving Trust conducted a campaign for CFLs with energy label
A. The overall objective of the campaign was to further the consumers’ purchase of compact fluorescent
lamps (CFL A’s) instead of incandescent lamps, so that the average stock of CFL A’s could be augmented.
- Requirement as to light efficacy. The requirement is that the CFL must be class A in accordance to EU’s
energy labelling directive.
- Requirement as to luminous flux reduction. After 2000 hours of use, the luminous flux must constitute no
less than 88% of the initial luminous flux.
- Requirement that the CFL A must be able to handle twice as many on/off’s in a lighting test compared to
the life expectancy in hours stated on the packaging. The lighting test is carried out with an on/off cycle of
½ min ON / 4½ min OFF, till there is no longer at least 50% that are live (cf. EU’s Quality Charter for
further details).
- Requirement that the colour reproduction index, R, must be at least 80.
- The colour temperature must be situated between 2,600 K and 3,000 K.
3.I EU Quality Charter
The EU Quality Charter was adopted on 19th July 1999 to help promote CFLs. It is not a requirement in any
sense, but aims to set the benchmark for better performing CFLs. Since its introduction, elements of the
Quality Charter have been adopted as requirements by labelling programs elsewhere, for example there are
many similarities with the Energy Saving Trust criteria and the EU Charter.
It should be noted that the EU policy towards CFLs has several components and while the policy trend in
Europe is to promote integral ballast CFLs in the short term, in the medium term the aim is to move towards
pin-type CFLs. The reason for this is that pin-type CFLs are most efficient, have a longer life and are
irreplaceable by incandescents.
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 42
As part of this longer term strategy, The Future Lamps Design Competition is aimed at overcoming the lack of
dedicated luminaries for pin-based CFLs in the residential sector [Conti et al 2002).

3.J Summary of Philippine Labelling Requirements
The Philippine Appliance Energy Standards and Labelling Program will introduce
mandatory labelling for self-ballasted CFLs in November 2005.
The test method will be IEC 60969 Edition 1.2:2001-03 "Self-ballasted lamp for general
lighting services-Performance requirements" standard, with 230 volts input.
Under the labeling program manufacturers and importers will be required to attach a label
the light output in lumens, power consumption in watts, the efficacy (lumens per watt)
and the average life to all compact fluorescent lamps with rated power consumption of
65 watts and below.
3.K Summary of Thai Labelling Requirements
Thailand has two voluntary labelling programs. The Energy Efficiency No. 5
Label is implemented by the Electricity Generating Authority of Thailand
(EGAT). The label is comparative and indicates the effiency, annual energy
consumption and the energy saving estimates, with No.5 indicating the
highest energy efficiency.
Testing is conducted under the Thailand Industrial Standard TIS 236-2533
(1990) with reference to IEC81:1984. A total of 121,900 CFL products from
several manufacturers including Philips, GE, Unilux, National, Osram and
Lampton, have adopted the label so far.

11. Introduction:
CFLs are now a highly significant globally traded commodity, and in many countries the sales value of CFLs
now exceeds that of equivalent incandescent lamps. As demonstrated in Figure 19, the volume of
production, the energy implications and the volume of international trade make this product type a high priority
for concerted and coordinated international action.

World CFL Sales
Total Energy Consumption
(Source: authors estimates)
CFLs have been available for over 20 years, and actively promoted as an energy saving device in residential
and commercial applications. At the present time CFLs are available in a wider variety of styles, at a lower
cost and in more outlets than ever before. The increasing use of CFLs, and the intense price competition, has
brought issues of product quality to the fore. Product performance has always been an issue; however the
sheer numbers involved now make this appear of greater significance.
Consumers in many countries have expressed their dissatisfaction with CFLs, particularly with respect to the
advertised service life and light output. In an effort to increase consumer confidence by identifying the better
performing models, several countries have adopted energy endorsement labels and/or minimum energy
performance requirements. These have proved successful; however the growth in international trade of
CFLs and the increasing number of national programs have highlighted the variation in requirements of these
different programs.
The purpose of this paper is to explore the potential for more effective global implementation through
harmonization over the next 2-3 years, and the possibility of reducing costs to regulators and manufacturers.
It is important to note that what is being considered is the harmonisation of both test procedures, and
performance standards – the levels specified for compliance.
This fits not only the World Trade Organisation agenda, but also that of regional groups such as Asia Pacific
Economic Cooperation (APEC), which are seeking to enhance trade through the advancement of common
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 49
standards. Trade enhancement includes not only potentially larger volumes but also lower costs of entry and
on-going compliance costs.
Note that in this paper, the following terms are used:
Criteria: The range of issues examined with respect to the performance of CFLs.
Test procedure: The methodology for testing a lamp to measure efficiency and other performance criteria, such as
those contained within a performance standard.
Performance standards: The performance levels specified by a program with respect to each of the criteria covered.

MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 51
13. Major Issues
This section highlights some of the major issues with respect to the international harmonisation of test
procedures and performance standards for CFLs.
13.1. Test procedures
There are currently several test procedures for CFLs used by the many countries identified in Tables 1
and 2, and these vary in terms of scope and methodology. This has the potential to lead to non-
comparable results and to limit international trading opportunities.
It is axiomatic that all lamps should be tested according to the same test standard incorporating all
necessary criteria to accurately measure performance. Potentially this could mean that lamps are
tested for conformity only once, at the point of manufacture – this will depend upon decisions
regarding mutual recognition (see below) – with those results accepted in the country of use.
The International Electrotechnical Commission publish two internationally used standards(often
reproduced in technically identical national standards):
IEC 60969 Self ballasted lamps for general lighting services – Performance requirements.
IEC 60901 Single capped fluorescent lamps – Performance specifications
Although these are called ‘performance standards’, these standards include test methods for a range
of criteria commonly specified with an endorsement labeling program. One option is for the IEC test
methods, or technically identical national standards, to be used in assessing compliance with
harmonized performance criteria.
It should be noted that one potential outcome of full harmonisation of test procedures could be the
development of a new range of CFLs capable of operating efficiently at any input voltage.
13.2. Mutual Recognition of test results
The extent to which each country recognises the results of tests undertaken elsewhere is an important
issue. For suppliers there are considerable benefits if the number of tests can be limited. However,
national energy efficiency agencies and regulators need confidence that the results are sufficiently
accurate to accept without further verification in order to discharge their national enforcement
responsibilities.
There will be a role initially for “round-robin” testing of CFLs amongst accredited laboratories across a
number of countries. This type of developmental testing provides data that leads to practical
improvements in the performance standards, enhancing the repeatability and reproducibility of results.
13.3. Self-ballasted vs Pin-type
Self-ballasted lamps comprise the majority of CFL sales internationally, and are included in the scope
of all current national energy efficiency programs covering CFLs. While pin-type CFLs are less
common, they may be strategically important as basis of some longer-term strategies to stimulate the
development of dedicated luminaries.
For practical reasons, it is recommended that groups committed to harmonization initially focus on
self-ballasted CFLs. Governments should also commit to incorporate pin-type CFLs within the
international program sometime in the future, after a similar standard development process and advice
to manufacturers.
13.4. Selection of key criteria
Although the range of criteria covered by existing national programs does vary, many are common to
most programs. It is likely therefore that agreement can be reached on a core set of criteria by
technical experts relatively easily.
Some criteria are necessarily specific to individual countries, such as electromagnetic disturbance,
and some safety requirements, and these may continue to be additional conditions which must be met
in individual countries over and above the international requirements.
It is therefore feasible for technical experts agree a set of criteria, harmonised internationally,
incorporating scope for additional requirements applicable to certain specified regions.
A suggested list of the core performance criteria for the international standard are:
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 52
Efficiency level
Lumen Maintenance
Rated Average Lifetime
CFL Lifetime Claims
Power Factor
Colour rendering
Mercury level
GLS Equivalence
Start-up time
A test procedure for each of these criteria is necessary in any internationally-harmonised test
procedure. These should be a mandatory requirement for testing, even if some criteria are not
specified within national standards program by some countries.
13.5. Accommodating difference levels of performance standards
More than one set of performance standards will be required, since countries wishing to implement
minimum energy performance regulations will usually wish to adopt levels which are less stringent
than those countries that desire to use only an endorsement label system, (designed to promote the
best-available-technology products). Such a tiered performance system also enhances the capability
of nations wanting to use a mix of both minimum performance standards and higher efficiency
requirements for product endorsement.
It is feasible to accommodate multiple performance criteria should countries require a greater range in
stringency levels, for example to denote existing and future standards. It should be noted that this
proposal is not intended to lessen the ability of countries to decide the performance levels for
minimum performance standards or endorsement labels which they consider appropriate, but to agree
where technology steps exists thereby limiting unintended trading difficulties for suppliers and to
encourage other countries to adopt measures for CFLs.
Further improvements in technology over time may warrant a higher stringency level than currently
envisaged, and the system will incorporate the capacity to improve and display compliance with that
improvement over time.
Consideration may need to given to whether different performance standards are required for lamps
designed to operate at different voltage/frequency combinations; or whether one set of standards can
apply universally.
13.6. Marking
A further consideration is whether there should be some marking of CFLs to indicate that they have
been tested according to the agreed standard and meet a certain standards in respect to the
performance criteria. If manufacturers test lamps according to agreed harmonised test procedure, then
the results could be marked on the lamp (and packaging) prior to shipment. This improves the
position of national regulators and competitors undertaking enforcement activities, since the declared
performance of the lamp will be displayed on every unit. This may replace the need in some cases for
importers to produce further test reports in the first instance – although when a product is suspected of
non-compliance, such evidence may be required.
Table 31 shows how such a system could work, using roman numerals to indicate compliance with
different performance standards. In this example, I is the lowest level of stringency, such as required
by a minimum performance standard. Level II is a more stringent MEPS level, perhaps introduced at
a later stage. Level III represents the level of criteria for an endorsement label, while level VI is
reserved for a future, higher, specification once the majority of products have achieved compliance
with level III. Further levels could be included as necessary.

Table 31: Illustration of Marking System for self-ballasted CFLs
Mark
(example)
Description Stringency
I Minimum energy performance standard (initial)
II Minimum energy performance standard (future)
III Endorsement label (initial)
IV Endorsement label (future)
It should be noted that this mark is not intended to be, and should not be confused with, any national
consumer energy efficiency label, such as an endorsement or comparative label. The mark would
compliment the enforcement of national endorsement, and could be made mandatory for lamps the
subject of financial incentive programs. Care will need to be taken to select a mark that is not
potentially confused with other compliance indicators.
A similar system has been agreed with respect to External Power Supplies, brokered by the National
Resources Defense Council (NRDC) between the following participating agencies: Australian
Greenhouse Office (AGO), California Energy Commission (CEC), China Certification Center for
Energy Conservation Products (CECP) and ENERGY STAR - United States Environmental Protection
Agency (USEPA).
14. The Way Forward
14.1. The opportunity
Informal discussions with energy efficiency agencies in a number of countries have indicated that
concerted international action is possible on the issue of harmonisation for CFL test procedures and
performance standards. The Workshop at Right Lights 6 provides an excellent opportunity to discuss
these issues openly and to canvass in-principle support from key organisations/countries to pursue a
greater level of cooperation in the future. This event can mark the agreement of parties to commence
an international project to harmonise testing and performance standards for CFLs.
14.2. Management of the project
Following this in-principle agreement, there will be a need for further liaison between countries,
facilitating the drafting of proposals and other coordinating functions. The Collaborative Labeling and
Appliance Standards Program (CLASP) and the Renewable Energy and Energy Efficiency Partnership
(REEEP) have expressed interest in providing this coordinating capacity, ensuring international
ownership of the project and maintaining the momentum created at the Right Light 6 conference. Both
of these organisations are independent of vested interests, with a mandate to assist all interested
parties involved in codes and standards development, and both can bring considerable international
support to the program.
Each participating country will need to commit to working cooperatively within this international
endeavour. On a practical basis, country partners should nominate as a point of contact, the
government official, technical expert, testing experts and local industry representatives who may
participate on this project.
14.3. Timing
Although it is recognised that some countries may be in a position to move faster than others, setting
deadlines will help to focus attention to our agreed tasks. Given the focus by many nations on test
methodologies, it should be possible for a common procedure to be proposed by an expert group
within 12 months and verified through an international round robin in 2006. Such a test procedure
should become an IEC standard no later than 2008. Given the existence of both minimum
performance standards and endorsement levels, it should be possible to agree a set of international
performance levels for existing technologies and to incorporate anticipated future performance levels
within an international framework document in 2006 with the implementation of such a scheme
remaining a decision for individual nations.
MEA 2005 Evaluation of MEPS and Endorsement Label Options for CFLs 54
14.4. Status of agreement
It is envisaged that participation in this effort will initially be guided by a non-binding agreement to
explore the issues of harmonisation further, as shown in Annex 1.
Within the next year work on testing, specification and mutual recognition issues could proceed in
parallel subject to a Memorandum of Understanding (MoU), for presentation and discussion at a
workshop in 2006.
In future, consideration could be given to more formal type of agreement, such a Mutual Recognition
Arrangement for the achievement of full harmonisation. It is suggested that this does not need
immediate attention; however some participants may have strong views which should be recognised
at an early stage.
14.5. Workshop outcomes
Participants should agree to three interrelated outcomes:
1. A list of national contacts should also be established at the workshop for international
publication
2. Settling a number of practical issues to allow the technical experts to proceed to develop the
desired test and performance standards:
a. Whether to develop unified performance standards for all permutations
voltage/frequency of supply or agree to develop two sets of performance standards for
the two main supply platforms
b. When to proceed with a round robin testing program to build confidence in the
proposed test methodologies
c. Whether to make mandatory the efficiency marking on product to declare compliance
to the corresponding performance standard
d. What type of agreement should be used to link participants to the project
e. An indicative budget for common elements of the project and the means for funding
those elements
3. Issue a communiqué within a reasonable period of this conference, which:
a. Identifies the countries and international organizations which have given in-principle
support to the pursuit of international harmonisation for CFL standards.
b. Identifies the organisation which will coordinate the project in the future, CLASP,
REEEP or the agreed organisation.
c. Announces the timeframe for harmonisation, eg. 2 years for the publication of the
methodology by at least one nation and 4 years by the IEC and the endeavour to
establish common steps in performance requirements.
d. Limits the immediate focus to self-ballasted type CFLs.
e. Commits to the key elements discussed in this paper:
i. Testing standards
ii. Performance standards
iii. Marking protocol
iv. Investigation of mutual recognition
f. The proposed wording of a communiqué is shown in Annex 1.

Annex 1: Proposed Items for Agreement
The following paragraphs have been drafted as the basis of an agreement to be endorsed by parties
at the Right Light 6 conference. They allow any parties to provide ‘in-principle’ support only for the
further develop of harmonisation plans, and are non-binding. While it is acknowledged that most
national organisations will need to initiate the required processes to gain ratification and further
commitment, these statements do nevertheless represent the first important step on the road of
harmonisation.
1. We, the undersigned, express our in-principle support for the development of a harmonised test
procedure for self-ballasted compact fluorescent lamps, with the aim of agreeing a final test
procedure during 2006 and to submit this test procedure to the IEC for publication as an
international standard.
2. We express our in-principle support for the development of an agreed set of performance
standards for self-ballasted compact fluorescent lamps, with the aim of reaching agreement during
2006. These performance standards will reflect varying degrees of stringency to match individual
national requirements for mandatory and voluntary implementation, for example to be used as
minimum performance standards or to indicate best available technology. Individual countries
would determine if and when these performance standards are to operate in that jurisdiction.
3. We express our in-principle support for a mandatory marking system for self-ballasted compact
fluorescent lamps designed to demonstrate (a) compliance with the testing regime, and (b) the
performance level achieved by the lamp under test. The intention is that this system would be
incorporated within the testing method standard and implemented by individual nations on a
timetable set by each country. We agree that this marking system is not intended to be, nor will it
attempt to supplant, energy efficiency labels that inform consumers about this product type.
4. We agree in-principle that each jurisdiction shall bearing their own costs for their own activities
and will agree to fund common development tasks from a fund established to operate from 2005-
2008, subject to further budgetary information becoming available. This fund will sponsor
coordination activities and the participation in standards development activities such as the round
robin testing of product.
5. We express our in-principle support for these activities to be coordinated by the Collaborative
Labeling and Appliance Standards Program (CLASP) and the Renewable Energy and Energy
Efficiency Program (REEEP).
