This site has been established for applicant and enrolled laboratories in the Energy Efficient Lighting Products (EEL) Laboratory Accreditation Program (LAP). On this site you will find important program information and links to documents required for successful participation in the program.

Program Description

The Energy Efficient Lighting Products (EEL) Laboratory Accreditation Program (LAP) was established by the National Voluntary Laboratory Accreditation Program (NVLAP) in 1991 at the request of the National Electrical Manufacturers Association (NEMA) to accredit laboratories that perform certain types of lamp and luminaire testing. The program has evolved to support EPA ENERGY STAR® and Department of Energy (DoE) lighting efficiency programs. NVLAP is recognized by the EPA as an ENERGY STAR® testing laboratory accrediting body (AB) and by DoE as a CALiPER accrediting body.

For information on the requirements of accreditation see NIST Handbook 150 which contains the general requirements for accreditation of laboratories. In addition, NIST Handbook 150-1 contains specific requirements for energy efficient lighting laboratories.

Proficiency Testing Requirements

Laboratories applying for IES LM-79 accreditation must participate in NIST solid state lighting proficiency testing. Testing must be successfully completed before IES LM-79 will be added to the scope of accreditation. Laboratories applying for IES LM-79 accreditation will be invoiced $3,350 US for the cost of enrollment in Round 2.

Periodically, NVLAP initiates interlaboratory proficiency testing for incandescent, compact fluorescent, and linear fluorescent testing laboratories. Round 14 of proficiency testing is expected to start in the fall of 2015. The approximate cost is $1,000 US and laboratories with these types of testing on their scopes will be notified and invoiced when the round begins.

Frequently Asked Questions (FAQs)

Q: How much does accreditation cost?

A: Laboratories no longer submit the on-site assessment fee with their applications. Based on the Test Method Selection List submitted with the application, assessor feedback, and the duration of the last on-site assessment, laboratories will receive an invoice from Universal Technical Resource Services (UTRS) shortly after completing the application. Additional information about fees for accreditation is published on the NVLAP Fee Structure page of the NVLAP website.

Laboratories located outside of the United States: Non-U.S. laboratories pay actual expenses for assessments and will be invoiced the full cost of the assessment shortly after submitting the application.

bullet-arrow  IES LM-86:2015, Measuring Luminous Flux and Color Maintenance of Remote Phosphor Components, has been added to the test method list as 22/S29.  An on-site assessment is required to add this test method to scopes since it is not sufficiently similar to other test methods.  If you are interested in adding this test method to your scope, please contact the lighting program manager to discuss options.

bullet-arrow  Round 14 of NVLAP incandescent/ CFL proficiency testing is underway. Labs will receive an invoice and artifacts in the fall of 2015. The protocol is similar to that followed in Round 13. If you do not receive a set of artifacts by December 1, 2015, please contact NVLAP.

bullet-arrow  Accreditation to ANSI C82.77-10:2014 --- Section 4 of ANSI C82.77-10:2014 requires LED lighting devices be tested by methods described in ANSI C82.16. ANSI C82.16 has not yet been published. NVLAP cannot accredit to C82.77-10:2014 until C82.16 is published. As soon as C82.16 becomes available, we will add C82.77-10:2014 to our Test Method Selection List.

bullet-arrow  Round 2 of NIST solid state proficiency testing will start January 1, 2015. All labs must participate in this second round if accredited for LM-79. It is estimated that it will take two years to cycle all labs through the program with labs participating in approximately the same order as they participated in the first round. The cost is $3,350 US with an option to test four-foot solid state fluorescent replacement tubes for no extra cost and CFL lamps for an additional $1,150. Labs will be notified by NVLAP and invoiced when a set of artifacts becomes available. Pass/fail results for Round 2 will be reported with formal corrective action expected for any outlying results.

bullet-arrow  NVLAP Lab Bulletin LB-85-2015Calibration Certificates for In-house Calibrations, has been issued effective February 24, 2015.
