Qualifying Criteria for Integral LED Lamps

Version 1.3

PDF version

Below are the product criteria for ENERGY STAR qualified Integral LED Lamps - Version 1.3. A product must meet all of the criteria in order to be qualified as ENERGY STAR.

Note: integral LED lamp products must be registered with the United States ENERGY STAR program (www.energystar.gov) before being sold in either Canada or the United States as ENERGY STAR qualified. Canada's ENERGY STAR initiative does not qualify integral LED products and asks that all organizations contact the US program directly to register their product and complete a US Partner Agreement.

Importers of integral LED lamp products into Canada must also follow these requirements. Manufacturers, distributors, and importers are also encouraged to sign an administrative arrangement with Natural Resources Canada. See section 6 for further details on how to qualify integral LED lamp products.

The references in this document to "safety" related standards do not necessarily reflect the equivalent "Canadian" mandatory requirements for integral LED lamps sold in Canada. However, these products are require to meet mandatory Canadian safety standards when sold in Canada, and Natural Resources Canada does not have jurisdiction in this matter.

1. Scope

These criteria apply to integral LED lamps , defined as a lamp with LEDs, an integrated LED driver, and an ANSI standardized base designed to connect to the branch circuit via an ANSI standardized lampholder/socket. These criteria include integral LED lamps of non-standard form, and those intended to replace standard general service incandescent lamps, decorative (candelabra style) lamps, and reflector lamps. Other types of replacement lamps may be added in the future as improvements to LED technology make LED use in other replacement lamp types viable.

4 Models based on statistical analysis of 432 PAR and 122 MR16 lamps produced by NEMA manufacturers are used to set minimum center beam intensity requirements. For a given target lamp wattage and target beam angle, mathematical functions for each lamp type yield the minimum required center beam intensity in candelas (cd). The minimum requirement is within two standard deviations of the center beam intensity predicted by the model.

8. Lumen Maintenance Testing and Life Claims

Minimum life requirement: 15,000 hours to 70% lumen maintenance (L70) for Decorative lamps (section 7B); 25,000 hours for all other lamp types. At least 6,000 hours of lumen maintenance testing of the full integral lamp is required of all lamp types. Products may not be qualified on the basis of component testing alone. Longer L70 life may be claimed based on verified lumen maintenance levels after 6,000 hours of lumen maintenance testing, as follows:

8A. Option for Early Initial Qualification with LM-80 and in situ Temperature Measurement Test

This option is available for integral LED lamps using single color or phosphor-converted LED package(s)/array(s)/module(s) for which LM-80-08 test data is available. The manufacturer may submit LM-80-08 data along with results of an in situ temperature measurement test (ISTMT)5 to verify the temperature of the LED package(s)/array(s)/module(s) when operated in the integral LED lamp. LED temperature is measured at the manufacturer-designated temperature measurement point (TMP). If the LM-80-08 data consistent with the ISTMT meets threshold requirements corresponding to the target L70 lifetime, the integral LED lamp is eligible for provisional approval after 3000 hours of long term integral lamp testing. Full qualification depends on successful completion of the full test period.

9. Certification

Manufacturers shall certify that ENERGY STAR qualified integral LED lamps sold using the ENERGY STAR certification mark have:

  1. Been tested by a third party and listed to UL Standard 1993 for Self-Ballasted Lamps and Lamp Adapters by a Nationally Recognized Testing Laboratory (NRTL) accredited by the Occupational, Safety, and Health Administration (OSHA).
  2. Met the manufacturers' declared performance and use criteria that are found on the packaging.
  3. Met or exceeded the minimum performance requirements contained in these ENERGY STAR Criteria for the characteristics shown above.

10. Qualification for Integral LED Lamp Products

Partners/Participants can submit their integral LED lamps for ENERGY STAR qualification by following the 2-step procedure below: To qualify LED Lamps without using the early initial qualification, submit all the test data from STEP 1 below except for LM-80-08 and TMP data, and submit 6,000 hour lumen maintenance data. Decorative lamps with a lifetime of 15,000 hours and other lamps with a lifetime of 25,000 hours may be fully qualified on the basis of 6,000 hour data. Longer lifetime lamps will only receive an initial qualification and then proceed to STEP 2 below.

A. STEP 1: EARLY INITIAL QUALIFICATION WITH LM-80-08 AND TMP VERIFICATION

Partner/Participant must submit a report that includes the following completed tests (see below) from an accredited or DOE CALiPER-recognized lab, which must certify to the authenticity and integrity of the test data. In addition, Partner/Participant must complete PAGE 1 and the accredited laboratory must complete PAGE 2 of the ENERGY STAR Integral LED Lamps Qualification Form and submit it with the packaging proofs and a product image or photo. A product photo will be required for qualification to assist in identifying the current version of the qualified product. This will also provide identification of the correct product for the Integral LED Lamps Third-Party Testing and Verification Program. The test reports must indicate that the model meets all initial requirements. Incomplete test reports, product packaging, or qualification forms will not be accepted or processed for ENERGY STAR qualification. Partners/Participants must complete the following tests or certifications before they will be considered for INITIAL ENERGY STAR qualification:

  • LM-80-08 data for LED package(s), array(s), or module(s) used in the integral LED lamp
  • Temperature Measurement Point (TMP) temperature verification of LED in the integral LED lamp
  • Lamp Base
  • Efficacy
  • Rapid-Cycle Stress Test
  • 3,000-hour lumen maintenance
  • Color Rendering (CRI)
  • Correlated Color Temperature (CCT)
    • Chromaticity measurements for each sample
  • Power Factor
  • Transient Protection
  • Operating Frequency
  • Electromagnetic Interference

Packaging Review: All Partners/Participants who are qualifying an integral LED lamp must submit electronic or hard copy labeling and packaging samples for the specific integral LED lamp model. Packaging must meet all of the requirements that are identified under the Lifetime Performance and Packaging Requirements. Failure to meet the packaging requirements will delay the qualification process and the integral LED lamp model in question will not be qualified until all packaging requirements are met. The specific qualified model must be distributed within this approved product packaging. If products are found being sold or distributed in alternative non-approved packaging, that model will be immediately disqualified from the ENERGY STAR program for failure to meet the criteria. If a Partner/Participant has multiple cases where products are being sold in unapproved packaging, this may cause their ENERGY STAR Partnership Agreement to be terminated.

Products that meet the above requirements will be considered initially qualified for ENERGY STAR and the Partner/Participant will receive correspondence (via e-mail or letter) stating the product has met all necessary initial requirements and can begin to market the integral LED lamp model as ENERGY STAR by using the certification mark on the product packaging, and identifying the product within marketing materials, and the company's Web site.

B. STEP 2: FULL QUALIFICATION:

Partners/Participants will be given a due date in their initial qualification correspondence to submit the final average rated life time test report to complete their ENERGY STAR Integral LED Lamp qualification process and fulfill the Full Qualification requirements. This due date will be based on the date the average rated lifetime test began and the rated lifetime of the integral LED lamp, which was recorded on the ENERGY STAR Qualification Form. Failure to submit this final test report within 60 days of completion of the test will result in an immediate disqualification of the model. After the final test report review, if a product does not meet the recorded average rated lifetime, then the disqualification process will be put into effect (see Sections 12 and 13).

Once a model has reached full qualification, it must be re-qualified every 36 months to ensure ongoing design or manufacturing changes maintain overall performance against the program requirements. See Section 16 for more information on the ENERGY STAR INTEGRAL LED LAMP RE-QUALIFICATION PROCEDURE.

C. UPGRADING THE LIFE CLAIM OF A PREVIOUSLY-QUALIFIED PRODUCT

Once a product has been qualified under the procedures above, ENERGY STAR Partners/Participants may increase the lifetime of a product only by demonstrating full compliance with the ENERGY STAR criteria at the new lifetime. Specifically, to increase the lifetime of a lamp, Partner/Participant must submit a report that includes the following completed tests from either their properly accredited laboratory or properly accredited third-party testing facility, which must certify to the authenticity and integrity of the test data:

  • Rapid-Cycle Stress Test as required at new lifetime
  • Lumen Maintenance at minimum required test period

In addition, Partners/Participants must complete PAGE 1 and submit it with the packaging proofs, which will be subject to the same review as in the initial qualification process. The accredited laboratory must complete PAGE 2 of the ENERGY STAR Integral LED Lamp Qualification Form and submit it with the test report. If Partner/Participant plans to initially qualify a product at 6000 hours, then later upgrade the lifetime, it is suggested that initial Rapid-Cycle Stress Test be completed in anticipation of final product lifetime.

11. Private Labelling Products

ENERGY STAR Partners/Participants may purchase existing qualified integral LED lamp products and submit them for ENERGY STAR qualification by completing and submitting a Private Labeler Qualification Form (available from your ENERGY STAR Integral LED Lamp Account Manager) and product packaging draft for review and approval. Once the private labeler form and product packaging have been reviewed and accepted, the private labeling Partner/Participant will receive correspondence from ENERGY STAR stating that the model will be added to the integral LED lamp qualified product list and can begin to use the ENERGY STAR certification mark on its packaging and marketed as an ENERGY STAR qualified product.

  1. Packaging for Private Labeled Integral LED Lamps:
    Partners/Participants must submit packaging proofs for each private labeled integral LED lamp. Packaging must identify the exact information (wattage, lumen output, rated lifetime, equivalency, etc.) their supplier has submitted to ENERGY STAR, since the products are exactly the same. If packaging is submitted with incorrect information, the model will not be qualified as ENERGY STAR until the correct packaging is submitted.
  2. Changing of Qualified Integral LED Lamp Supplier:
    Partners/Participants are required to inform ENERGY STAR within 30 days of changing their supplier of one or more of their private labeled integral LED lamps. Partners/Participants must submit a new Private Labeler Form or enter new information into an online product qualification tool along with new product packaging for each product to reflect the updated information.

NOTE: The private labeled products, or products with different model or product numbers, fall under the same quality assurance and disqualification protocol as the originally tested model. Therefore, if the original qualified model is disqualified from the ENERGY STAR program, the corresponding private labeled model(s) will also be disqualified from the ENERGY STAR program.

12. Commercial Packaging of Products

ENERGY STAR qualified integral LED lamp products that will be bulk packaged for retail or commercial sales must submit a package proof for the container that the qualified products will be shipped in and that clearly displays all of the required criteria to fulfill the packaging requirements for ENERGY STAR.

NOTE: Those Partners/Participants found distributing qualified integral LED lamp products in unidentified packaging or white boxes will be contacted immediately and may have that specific model disqualified from the program. Once all requirements have been met for packaging, ENERGY STAR will add the new private labeled integral LED lamps to the ENERGY STAR qualified lists and searches. All labeling must be in accordance with ENERGY STAR Identity Guidelines found in the Partnership Agreement/Program Requirements and FTC's Appliance Labeling Act regulations. In Canada, all labeling must be in accordance with Natural Resources Canada's labeling regulation and the document Full Guidelines for Reproducing, Applying, and Using the ENERGY STAR Symbol in Canada available at (http://www.oee.rncan.gc.ca/residential/business/manufacturers/guidelines.cfm). Packaging and promotional materials using the certification mark should be submitted to your ENERGY STAR Integral LED Lamp Account Manager for final review and approval.

13. Quality Assurance

Original Equipment Manufacturers (OEM) Partners/Participants will be required to provide documentation that describes the measures they are taking to assure their ENERGY STAR qualified integral LED lamp and those products they sell to private labelers meet program and criteria requirements.

  1. Manufacturing Quality Control Documentation
    EPA will accept any of the following industry quality control processes:
    • Adherence to the International Standards Organization (ISO) 9000 family of international quality management standards and guidelines, used as the basis for establishing quality management systems.
    • Employment of the Six Sigma methodology to measure and improve a company's operational performance, practices and systems; or an equally recognized industry process.
    • Other quality control systems or formats that are accepted industry standards.
  2. Color Consistency
    The following quality requirements must be met during the production runs of each lamp model:
    1. The lamp manufacturer is required to maintain color control such that a minimum of 90 percent of the ongoing production (as represented by samples tested from each production shift for the same color and when typically evaluated over 12 month period) will fall within the ANSI C78.377-2008 chromaticity quadrangle associated with the designated (manufacturer declared) target color.
    2. For the purposes of meeting color control, the lamp manufacturer must maintain testing equipment calibrated to international practices and standards and must compile the ongoing color control data in a manner so that it can be easily reviewed upon EPA request.
    3. At a minimum, the manufacturer's color quality control program must maintain the following information for a 3-year period:
      1. Test dates and sample size (minimum of two lamps per production shift)
      2. Test results (x,y) for each sample lamp measured
      3. Test results (all x,y data) for sample lamps plotted graphically against the designated chromaticity quadrangle and available for review at least on a quarterly basis (See Appendix A)
      4. Records to substantiate that 90 percent of the (x,y) data points fall within the applicable chromaticity quadrangle. Manufacturers are encouraged to exceed this target.

14. Independent ENERGY STAR Integral LED Lamp Third Party Testing and Verification Program

Manufacturer (including Private Labelers), distributor, and retailer Partners/Participants who are active members of the ENERGY STAR Integral LED Lamp Program must participate in the ongoing, integral LED lamp Third-Party Testing and Verification Program, which uses independent, third-party, NVLAP accredited facilities. This third-party testing program is necessary to provide an active system to verify quality of ENERGY STAR qualified integral LED lamp products in the marketplace. This program will conduct random off-the-shelf testing of ENERGY STAR qualified integral LED lamps and provide the results to the Partner/Participant.

  1. An independent program has been selected as the means for third party testing for several fundamental reasons, including:
    • It will allow for fair and open assessment of third party test data for the U.S. EPA
    • It will serve as an effective firewall for proprietary data sent to the ENERGY STAR Integral LED Lamp Program contractor.
  2. The goals of the Third-Party Testing and Verification Program are to:
    • Develop an integral LED lamp testing program that will aid EPA in maintaining quality control of the ENERGY STAR Integral LED Lamp Program;
    • Develop a mechanism providing added assurance to ENERGY STAR Partners/Participants that sponsor Integral LED Lamp Programs and to manufacturer competitors alike that qualified products do in fact meet the ENERGY STAR criteria;
    • Provide a basis upon which the EPA can reasonably make decisions on disqualifying products not exhibiting the necessary qualifications to keep its ENERGY STAR qualification status; and
    • Maintain the precepts of the ENERGY STAR Program, the highest of which is that the consumer receives superior products that perform as advertised.
  3. Third-Party Testing and Verification Program will be managed using funds derived from a percentage of testing fees and will have a product selection working group. This working group shall be representative of both manufacturer and non-manufacturer stakeholders, as described below.

    Product Selection Working Group

    The Product Selection Working Group will oversee the final product selection process for each testing cycle.

    The Product Selection Working Group will be comprised of five representatives – two members from industry (ENERGY STAR integral LED lamp manufacturers, retailers, or distributors), two members from an ENERGY STAR state, utility, or energy-efficiency program sponsor Partners and EPA, which will serve as the committee chair. The Third-Party Testing Program Administrator will assist the committee.

    To be eligible to serve on the Product Selection Working Group, candidates must be recommended or nominated by a current ENERGY STAR Partner/Participant (which includes manufacturers, retailers, utilities, states, or energy efficiency program sponsors). The main criteria for membership on the product selection working group will be an unbiased view of the existing integral LED lamp marketplace, knowledge of current lighting market trends and consumer practices, and a demonstrated ability and desire to contribute to improving the overall quality of ENERGY STAR qualified integral LED lamps. EPA will review nominations and select the candidates to serve on the working group. Once the working group has been established, the members will serve for a period of two years. Working Group members can be re-nominated to serve another two years once their term is completed.

  4. Third-Party Tests and Verification to be conducted
    All tests and certifications listed below will be conducted as per the qualification stipulations of the current ENERGY STAR criteria for integral LED lamps. These tests and certifications will form the basis for product qualification verification:
    • Base
    • Efficacy
    • Luminous Intensity Distribution
    • Rapid-Cycle Stress Test
    • Correlated Color Temperature (CCT)
      • Chromaticity measurements for each sample
    • Color Rendering Index (CRI)
    • Color Spatial Uniformity
    • Lumen Maintenance at appropriate interval according to product's claimed lifetime (Table 1 above)
    • Power Factor
  5. Product Nomination, Selection and Procurement Process
    Nomination and testing cycles will be conducted biannually. The product nomination and selection timetable and process will begin after the criteria are finalized. The schedule below is an example and subject to change based on effective date of the criteria:

    1st Cycle Distribution of Nomination Forms: March 15
    1st Cycle Random Product Generation: March 20
    1st Cycle of Product Nomination Due: April 15
    1st Cycle Review of Product Nominations (with randomly selected products): April 28
    1st Cycle Final List of Products: May 15
    1st Cycle Product Procurement: May 10-June 30
    1st Cycle Product Testing Begins: July 1
    2nd Cycle Distribution of Nomination Forms: September 15
    2nd Cycle Random Product Generation: September 20
    2nd Cycle of Product Nomination Due: October 15
    2nd Cycle Review of Product Nominations (with randomly selected products): November 1
    2nd Cycle Final List of Products: November 15
    2nd Cycle Product Procurement: November 15-Jan 31
    2nd Cycle Product Testing Begins: February 1

  6. Product Nominations
    1. Products will be selected for third party testing on both a random and nomination selection basis. The program will target to test 20% of the total number of current qualified bulbs during a calendar year; half of the products will be selected via a random generator, the other half will be selected by EPA and participating ENERGY STAR Partners/Participants (utilities, manufacturers, states, energy-efficiency program sponsors, or other government entities (e.g., Natural Resources Canada)).
    2. The product testing pool will be comprised of all ENERGY STAR qualified integral LED lamps models.
    3. A maximum of six models per integral LED lamp Partner/Participant may be tested within the fiscal year (two-cycle timeframe).
    4. Qualified integral LED lamp products that are within six months of their requalification date will be excluded from an upcoming testing cycle.
    5. Following the suggested schedule timeline, the Third-Party Testing Program Administrator will send all Partners/Participants a nomination form to complete. The parties who wish to nominate products will be required to submit their nominations electronically by the specified deadline to the Third-Party Testing Program Administrator.
    6. During the 30-day product nomination timeframe, the Third-Party Testing Program Administrator will generate a list of qualified products through the random generator. This initial product list will be reviewed to identify which products are readily available in the marketplace and which products are not. Those products that are not readily available in the marketplace will be removed from the nomination group.
    7. Integral LED lamp Partners/Participants who wish to nominate other Partners/Participants' ENERGY STAR qualified integral LED lamps will be required to follow the nomination guidelines. The basic guidelines will address the following:
      • Product nomination limits: Nominations will be limited to no more than two models per manufacturer per testing cycle. There is no upper limit for total number of nominations.
      • Rationale for product nomination: Will need to supply evidence on the poor performance of a product, which can include test data, consumer complaints, product returns, etc. Nominations submitted without ample evidence to demonstrate the need for third party testing will be disregarded. All other Partners/Participants (e.g. state, utility, or energy-efficiency program sponsor Partners) can nominate an unlimited number of integral LED lamp products.
  7. Product Selection

    Submitted product nominations forms will be collected and compiled with the list of randomly selected products by the Third-Party Testing Program Administrator.

    The Third-Party Testing Program Administrator will distribute the overall list of product nominations (random generator and Partner/Participant nominations) to the Product Selection Committee to review. The Third-Party Testing Program Administrator will organize a conference call (or meeting) with the Product Selection Committee to discuss the product nominations and finalize a list of products to test within each cycle. The Product Selection Committee will have five business days to review the nominations and approve the final list of products to test per testing cycle.

    EPA will approve the final product list and then the Third-Party Testing Program Administrator will contact each INTEGRAL LED LAMP Partner/Participant to inform them their product or products will be tested. In addition, the Third-Party Testing Program Administrator will also notify the Partner/Participant of which participating NVLAP accredited laboratory they will be working with.

  8. Costs of Third-Party Testing and Verification Program and Laboratory-Partner Logistics
    Partners/Participants will pay for the testing of their products. The testing fee will vary as a function of the rated lifetime of the product and all participating laboratories will provide fixed fees. Included in the fee will be a per model charge for the Third Party Program Administrator services, which will not exceed 20%.

    Each participating laboratory will provide the established quotation (based on the rated lifetime of the product) to the specific ENERGY STAR integral LED lamp Partner/Participant. This quotation will include the fixed fee for testing, procurement, and shipment. In addition, the laboratory will provide a confidentiality clause that automatically permits the test laboratory to release the data only to the Third Party Testing Program Administrator and to the manufacturer. Partners/Participants will send payment directly to the testing facility within the allotted timeframe. Administrator fees will be distributed by the laboratory to the Third-Party Testing Program Administrator.

    Costs for product procurement will be set at a flat fee plus the total retail costs of the samples (to be determined by participating laboratory(ies)). The flat fee costs cover the logistical costs to purchase the products (transportation, telephone, hotel, etc.). The laboratories will work to identify the best retail price to procure the products. The procurement prices will be reviewed after each cycle to identify whether the cost needs to be adjusted.

    Costs for product shipment to the testing facility will be a uniform cost (to be determined once participating laboratory(ies) have been selected for the program).

    Third-Party Testing Program Administrator Fees will cover (estimating 20% of overall testing costs):

    • Test Report Development
    • Coordination of accredited NVLAP laboratories
    • Verification of Qualified Product Information
    • Coordination of Technical and Nomination Committees
    • Notify Partners/Participants of product selection and provide selected laboratory information
    • Administrative tasks (conference calls; mailings; etc.)
    1. Product Procurement: Partners/Participants will assist the assigned laboratory in identifying distribution channels to purchase products from and products will be purchased from these identified retail sources or Internet shopping venues. At a minimum, at least two different date or lot codes will make up the samples of bulbs per model tested. Products will be purchased in accordance with these procurement guidelines:
      • Store Selection: If available, samples must be purchased from a minimum of three different retail or commercial outlets.
      • Geographic location selection: At a minimum, samples must be purchased from two (2) separate geographic regions of the U.S. The recommended number of locations is four (4).

      The following information will be recorded to assist in clarifying any issues that may arise in the testing process:

      • Lot numbers
      • Date code
      • Geographic location of purchase (city, State, zip code, store number)
      • Retailer or distributor where product was purchased
      • Product Photo
      • Product Packaging
    2. Information Flow and Data Management: Each Partner/participant having product tested will receive the complete test reports for its product(s) directly from the testing laboratory. The Third-Party Testing Program Administrator will also receive the complete testing reports from the testing laboratory. The Third-Party Testing Program Administrator will deliver the compiled test results to EPA to review and identify which products met the ENERGY STAR criteria.

      EPA will notify Partners/Participants of one of the following outcomes:

      • Qualification verification
      • Disqualification of the product

      The Third-Party Testing Program Administrator will be responsible for archiving information for each testing cycle to develop consolidated trend data reports. These data reports will include:

      • Overall pass/fail statistics
      • Pass/fail statistics by product type
      • Statistical scatter plots of measured performance test data
      • Statistical analysis of mean, median
      • Year-by-year or round-by-round trend data

      The Third-Party Testing Program Administrator will prepare a consolidated trend data report that will include all trend data of the tests identified in section 14.D. This report will be made available to interested parties.

    3. Testing Review Process: Based on the results and incorporation of measurement tolerances, EPA will categorize the tested products into two groups:
      • Qualification verification
      • Disqualification of the product

      Qualification verification is defined when a product meets or exceeds all of the ENERGY STAR qualification testing or Third-Party Testing requirements.

      Disqualification is defined when a product fails one or more of any of the ENERGY STAR qualification testing or Third-Party Testing requirements. If a product is so categorized, EPA will begin the disqualification and appeals process.

      Additional and/or separate off-the-shelf testing may be conducted on behalf of NRCan by an accredited facility based on complaints or other suspicion of noncompliance, or as part of a random test program. If a model fails a requirement in the independent, third-party quality control verification and tests or off-the-shelf testing, ENERGY STAR may request further testing by the Participant or other actions to be taken by the manufacturer to demonstrate why the product should keep its qualification status and not be delisted as an eligible product. If the data shows clear proof that the product in question has overwhelmingly failed to meet the criteria, ENERGY STAR will immediately disqualify and remove the integral LED lamp model from the qualified product list. Disqualification or delisting of a model may also result from evidence of noncompliance with the ENERGY STAR Participant Arrangement and/or criteria.

15. Disqualification Process

Partners/Participants shall refer to EPA's stakeholder letter dated July 20, 2010 (See Appendix E) for the product disqualification procedures and corrective action requirements.

16. ENERGY STAR Integral LED Lamp Re-Qualification Procedure

Once a model is qualified, it must be re-qualified every 36 months to ensure ongoing design or manufacturing changes maintain overall performance against the program requirements. To re-qualify a product, Partners/Participants must follow the current ENERGY STAR INTEGRAL LED LAMP qualification testing procedure and complete all of the required tests. The ENERGY STAR Integral LED Lamp Program contractor will track and inform Partners/Participants when their qualified products must begin testing for re-qualification.

The 36-month re-qualification clock will not start until the product has achieved full qualification under (completion of all required tests including average rated lifetime test). Specifically, Partners/Participants must:

  1. Submit their product for requalification testing at an accredited NVLAP testing facility within 45 days of notification from the ENERGY STAR integral LED lamp Account Manager.
  2. Submit the test qualification reports and product packaging to the ENERGY STAR integral LED lamp Account Manager for review and approval.

Products that meet the ENERGY STAR criteria will continue to be recognized as ENERGY STAR qualified. Products that fail to meet the criteria will be categorized for immediate disqualification.

17. Retirement/Discontinuation of Products

Partners/Participants who are discontinuing or retiring a model need to submit to their ENERGY STAR integral LED lamp Account Manager a formal letter stating the specific date this model will be out of the marketplace so it can be identified on the qualified product list as "retired/discontinued " since it will no longer be available.

18. Effective Date

The effective date for the ENERGY STAR Program Requirements and Criteria for Integral LED Lamps – Version 1.3 is August 31, 2010.

All products must re-qualify for ENERGY STAR within three years of the full qualification date.

19. Future Criteria Revisions

ENERGY STAR reserves the right to change the criteria should technological and/or market changes affect its usefulness to consumers, industry, or the environment. Within one year of the effective date of this version, ENERGY STAR will review comments and suggestions for future revisions to the current criteria.

Appendix A: Chromaticity Specification and Tolerance Quadrangles

This chromaticity specification below was developed by ANSI to be as consistent as possible with existing fluorescent lamp standards, and to reflect the current (and near future) state of SSL technology and color binning capabilities. Each of the eight quadrangles as defined below overlap the six current ANSI 7-step MacAdam ellipses (consistent with the current ENERGY STAR lighting criteria), and thus have the same nominal CCT as ENERGY STAR fluorescent lamps. Two additional CCTs (4500 and 5700K) are included to encompass the additional CCTs available in SSL. Each quadrangle is defined by the range of CCT and the distance from the Planckian locus on the chromaticity diagram. Refer to ANSI C78.377-2008 for the details of these definitions. Figure 1 shows the plot of these chromaticity quadrangles and the table below shows (x,y) coordinates of the center points and the corners of each quadrangle.

Appendix D: In situ Temperature Measurement Test (ISTMT)

NOTE: the ISTMT is required only for products using the option for early initial qualification with LM-80-08 test data and ISTMT described in Section 8A.

IESNA LM-80-08 defines lumen maintenance testing for LED packages, arrays, and modules. Because LEDs are incorporated into integral lamps with heat sinks, optical elements, power supplies, etc. and then operated in a variety of ambient environments, LM-80-08 by itself is not a predictor of integral lamp lumen maintenance. To relate the results of the LM-80-08 test to the integral lamp, DOE requires verification of LED temperature in environments that simulate real-world applications (in situ) with tests that measure the temperature of the highest temperature LED in the integral lamp at steady-state thermal equilibrium. The procedure is called the In situ Temperature Measurement Test (ISTMT) which follows ANSI/UL 1993-1999 Standard for Self-Ballasted Lamps and Lamp Adapters. It includes the addition of a thermocouple attached to the LED package, array, or module used in the integral lamp.

Temperature Measurement Point (TMP)

LED package, array, or module manufacturers designate specific locations on their products which act as surrogate points for measuring junction temperature (Tj). DOE generically designates these locations as the temperature measurement points (TMPs) for the purposes of measurement in testing.

Knowledge of the thermal pathway between the LED die junction and a designated external measurement point on the package, array, or module allows manufacturers to accurately estimate junction temperature. The surrogate temperatures and their measurement locations vary from manufacturer to manufacturer. Some manufacturers use temperatures measured at the solder joint (Ts) at the board attachment site; some use the package case temperature (Tc); and others use the board temperature (Tb) on the module. Collectively, these locations serve the same function, i.e., to correlate an external temperature to the junction temperature, which is critical for determining LED lumen maintenance. For purposes of this document, the measurement locations for Ts, Tc, and Tb are TMPs.

Conditions for Use

To be eligible for the optional early initial qualification with LM-80-08 and ISTMT, ALL conditions below must be met. If ANY of the conditions is not met, the early initial qualification option may not be used.

  1. The LED package(s), array(s), or module(s) used in the integral lamp have been tested according to LM-80-08.
  2. The LED package/array/module manufacturer prescribes/indicates a temperature measurement point (TMP) on the package, array, or module.
  3. The LED package, array, or module TMP is accessible to allow temporary attachment of a thermocouple for measurement of in situ operating temperature. Access via a temporary hole in the lamp (no larger than 9.525 mm (0.375") diameter), tightly resealed during testing with putty or other flexible sealant, is allowable. The size and location of the access port shall be documented in the submittal for the purposes of repeatability.

The ISTMT follows UL 1993 with the addition of a thermocouple attached to the highest temperature LED package or module in the integral lamp (i.e., at TMP).

Guidance for Thermocouple Attachment
  • Manufacturers shall select and designate the highest temperature LED package, array, or module in the integral lamp. In most cases the individual LED in the middle of symmetric arrays should be hottest. A well-designed thermal management solution will minimize the temperature gradient across packages.
    • For square/rectangular/circular arrays the individual LED closest to the center.
    • For other configurations it is recommended manufacturers sample several LEDs to find the highest temperature device within the integral lamp.
  • Temperature probes shall be in contact with the TMP and permanently adhered. Permanent adhesion consists of high temperature solder, conductive adhesives (e.g., accelerator/UV activated or epoxy), or melting the tip into plastic or other approved product recommended by the temperature probe manufacturer. Tape alone is not acceptable for providing good thermal contact at the thermocouple/TMP interface.
  • The thermocouple tolerance shall conform to ASTM E230 Table 1 "Special Limits" (≤ 1.1°C or 0.4%, whichever is greater).

Dear ENERGY STAR Lighting Manufacturing Partner:

As you may know, the ENERGY STAR program is undergoing significant programmatic changes. Enhanced testing and verification requirements currently under development will bolster program integrity, and thereby ensure the continued success of ENERGY STAR, its value to consumers who have come to rely upon its logo to distinguish energy-efficient products, and its value in the marketplace for manufacturers and retailers. This letter clarifies product disqualification procedures for lighting products.

EPA currently maintains two ENERGY STAR lighting verification testing programs. For compact fluorescent lamps ("CFLs"), the CFL Third Party Testing and Verification Program verifies the performance of qualified CFLs by testing off-the-shelf products. For residential light fixtures, the Quality Assurance Testing Program ("QA4") verifies the performance of off-the-shelf qualified light fixtures. The development of similar verification testing programs is cited in the Solid State Lighting (v1.1) and Integral LED Lamp (v1.1) specifications. As detailed in the ENERGY STAR Qualified Lighting Integration Proposal, it is EPA's intention to consolidate the aforementioned programs into one Lighting Verification Testing Program.

The broad programmatic changes being developed for ENERGY STAR necessitate specific changes to the ENERGY STAR lighting program to ensure consistency throughout ENERGY STAR, and equity in the market place. The policies and procedures identified in this letter pertain to the current lighting verification testing programs as well as to any future qualifying or verification programs, including the consolidated program. Product disqualification procedures and corrective action requirements for lighting products will now include the following elements:

  • The partner must immediately stop shipment or delivery worldwide of the model with the ENERGY STAR mark until the label is removed or covered.
  • The partner must inform everyone in the distribution chain for this model, including but not limited to, all on-line and in-store retailers, that the model does not qualify for ENERGY STAR.
  • The partner must remove or cover up the ENERGY STAR mark on product units within its control and take necessary steps, as determined by EPA, to ensure the logo is removed or covered by those entities in the distribution chain that now have control of any product units.
  • The partner must remove or cover up the ENERGY STAR mark on collateral materials such as product packaging, product spec sheets, web pages, and other marketing materials associated with the product.

EPA reserves the right to terminate a partnership for a number of reasons; however, a pattern of product disqualification will automatically trigger consideration of partnership termination. In addition, failure to participate in required testing will result in partnership termination with a 12-month moratorium before a new partnership application may be approved. In all instances, a lighting manufacturer is ineligible for ENERGY STAR partnership if it does not sell qualified products in North America.

To the extent that the policies and procedures described here differ from what is stated in other ENERGY STAR lighting product procedures and specifications, such as, e.g., the Quality Assurance Testing Guidelines and Procedures Manual (Version 2.0, April 2007), and the ENERGY STAR Program Requirements and Criteria for CFLs (Version 4.0, March 2008), the statements made in this letter supersede those. For questions regarding this letter, please contact Leslie Jones at (202) 343-9305 or jones.lesliea@epa.gov.

Thank you for your continued participation with and support of the ENERGY STAR program.

Sincerely,

Ann Bailey
