Transitions…
Summer 2002 IFC solicited “ELI Legacy Guardian” international proposals
Evaluated multiple proposals Continued market evaluation & strategy
development through Spring 2003 IFC engaged China Certification Center for
Energy Conservation Products (CECP) to develop a business plan by January 2004.
Why CECP?
CECP has demonstrated ability to execute business model based on manufacturer fees
Access to Chinese lighting industry Experience with manufacturer process
certifications (big impact on quality) Opportunity to harmonize ELI, China Green
Lights and perhaps ENERGY STAR tests
New strategies for ELI…
No longer built on retail/consumer demand Respond to market demand from bulk
purchasers who want to differentiate products and get good quality
Reach out to “big box” retailers, government & utility DSM programs
Require manufacturers to pay small fee
Other ELI Products…
Traffic signals: Light emitting diodes (LEDs) can save 85% of the energy used by incandescent lamps!
Linear fluorescent lamps + electronic ballasts
Outdoor residential CFL luminaires Indoor residential CFL luminaires Public area lighting Others as requested by new participants

Results of CFL Results of CFL Performance TestsPerformance Tests
ELI products conform to a voluntary energy efficiency and quality specification.
From 2000 to present, ELI has approved the use of the quality mark by 11 manufacturers, for over 120 models of compact fluorescent lamps.
In 2002 ELI launched its random testing program of products marketed in seven developing countries.
The Lighting and Appliance Testing Laboratory, Department of Energy, The Philippines, performs the tests.
To gain approval to use the ELI “green leaf” logo,manufacturers…
Fill out a detailed application form for each model,
Submit performance test data, and Certify that product is manufactured in a
factory operating a quality assurance system in accordance with ISO 9000-2000 or equivalent.
Manufacturers’ test results must be…
Obtained from a nationally accredited laboratory (according to ISO 17025) or an equivalently qualified facility.
Conducted on 10 samples for electrical performance
Conducted on 3 samples for photometric performance.
Submitted within 2 years of testing.
Technical review and approval
Each application is reviewed for completeness and compliance by ELI administrative team and the technical consultant.
If a model is approved for quality mark use it is posted to ELI’s publicly accessible website: www.efficientlighting.net
Summary of ELI CFL Voluntary Specification (July 2002)
Efficiency (lumens per watt) If CFL has either an integral or a separate ballast
At input power of <15 W: 45 lm/W
At input power of 15 W and >4000 CCT: 55 lm/W
At input power of 15 W and <4000 CCT: 60 lm/W If CFL has a translucent cover
At input power of 14 W: 40 lm/W
At input power of 15 to 19 W: 48 lm/W
At input power of 20 to 24 W: 50 lm/W
At input power of 25 W: 55 lm/W If CFL has a reflector
At input power of <19 W: 33 lm/W
At input power of >19 W: 40 lm/W
Also in the ELI specification…
Average rated lifetime: 6000 hours Lumen Maintenance: 80% of initial output
maintained to 2000 hours Color rendering index (CRI) of 80 or higher
CFL package bearing ELI quality mark must show…
Rated input power (watts) Light output (lumens) Average rated lamp life (hours) Equivalency to general service (incandescent)
lamps Correlated color temperature (CCT) Minimum starting temperature One-year “no questions asked” warranty in
at least one local language.
RESULTS RESULTS
Initial, 100-, 1000- and 2000-hour tests conducted for each of 49 models (n=624 units).
6000-hour results for Round One, 31 models (n=372 models).
Input power demand: Initial reading of the power dissipated by a lamp shall
not exceed the rated wattage by more than 5%, per IEC. All models complied with this criterion.
Input power demand remained stable for all models throughout the testing.
Lamp efficacy (luminous efficacy):
Initial light output value / initial input wattage
@ 100 hours: 42 to 65 lm/w. @ 2000 hours: 26 to 56 lm/w. @ 6000 hours: 22 Round One:19 to 51 lm/w. Compared to the efficacy calculated from the 100-hour
measured values, there was a marked change in efficacy at 2000 and 6000 hours.
Efficacy declined by 17% to 56% from 100 to 6000 hours.
Initial light output : (rated values vs. measured values)
1 @ 80% 3 @ 89%-91% 10 @ +5% 13 @ 106% to 110%
15 @ 111% to 119%
4 @ 120% to 126%
Lumen maintenance
At 2000 hours… Two-thirds @ >80%. 10 (including 4 encapsulated) @ 86%-89%. 26 @ 80%-85%. 9 @ 70% to 79%.
1 encapsulated @ 61%.
For 21 Round One models still operating at 6000 hours: 62% to 82%.
Lifetime
100 hours: 4 units failed 1000 hours: 9 units failed 2000 hours: 19 units failed; however, >50% for
every model still operating. 6000 hours: 22 of the 31 models passed,
including all 6 encapsulated. 6000 hours: 9 models failed. 5 between 5036
and 5839 hours ;4 between 5000 and 2770 hours.
Power factor: At 100 hours, 5 @ 45% to 49%. Remainder exceeded 50%.
Lamp start-up time: All illuminated continuously within 1.5 seconds.
Run-up light output: Lamp stabilization time of 10 minutes; light output
measured at 120 seconds @ 80% of the 10 min. l.o. Only 3 models failed to meet this requirement.
Correlated color temperature (CCT): Very close to manufacturers’ claims.
Labeling and packaging
Minimum starting temperature was not specified in most of the models’ packaging.
More than half of the models’ packages did not include the standard efficacy and color temperature ratings.
Some ELI-qualified models lacked the ELI logo.
DISCUSSION
ELI tested as many units and models as resources permitted.
Sample size was not large enough to make broad generalizations about CFLs…but,
Sample was large enough to indicate serious performance problems.
Evidence valuable for follow-up actions with manufacturers, and for anecdotal comparisons with other organizations’ results.
Is “Pass or Fail?” the right question?
Six of the 28 ELI models tested in Round One met all of the ELI requirements.
They demonstrate that the specification is within the realm of possibility for mass-marketed products, and that the specification is stringent enough to separate the best performers from the others.
“Pass or Fail?” is a relevant question.
However…
22 models failed to meet ELI’s specification. Of these, 11 failed by only one measure.
Some were early entries in the program & were granted exceptions on some requirements.
The qualification period for approved models is only 2 years, so the older entries are being reviewed for renewal according to the current specification.
Here, “pass or fail” is less relevant; More useful are the pass or fail results for each characteristic, because these will shape future revisions of the specification.
Messages to Manufacturers
WE CONGRATULATE THOSE WHO WE CONGRATULATE THOSE WHO PRODUCE BEST PERFORMING CFLS!PRODUCE BEST PERFORMING CFLS!
ELI will encourage revised labels (for greater accuracy), May request results from a larger or different sample of
units. (Some failed certain measures by only a small amount—perhaps given larger samples these models would “pass”),
Ask for voluntary removal of products that had poor light output, lumen maintenance or life test results, and
Reserve the right to “delist” models that do not fully comply with the ELI specifications.
Of Continuing Concern to Consumers & Advocates
Claims of light output and “equivalency” to incandescent lamps are consistently overstated by manufacturers.
This concern is substantiated by evidence from other testing programs, too.
Consumers notice this performance differential; it could become a “market spoiler.”
ELI successfully negotiates with manufacturers for more accurate labeling.
Next Generation ELI
Recruit and process product applications through 2005. Transition to a team including the China Certification
Center for Energy Conservation Products (CECP). Concentrate on market aggregators, such as large
retailers and electric utility or government programs, rather than on residential consumers.
Refine the menu of lighting products tested and promoted.
Collaboratively seek global, harmonized test methods.
