NOTIFICATION 
 
The following notification is being circ ulated in accordance with Article 10.6 
 
1. Notifying Member:  UNITED STATES  
If applicable, name of local governme nt involved (Article 3.2 and 7.2):     
2. Agency responsible:  Office of Energy Efficiency  and Renewable Energy (OEERE), 
Department of Energy (DOE) (715) 
Name and address (including telephone and fax numbers, email and website 
addresses, if available) of agency or authority designated to handle comments regarding the notification shall be indicated if different from above :    
3. Notified under Article 2.9.2 [X], 2.10.1 [   ], 5.6.2 [   ], 5.7.1 [   ], other:   
4. Products covered (HS or CCCN where applicable, otherwise national tariff heading. 
ICS numbers may be provided in addition, where applicable):  Light-emitting diode 
lamps (ICS 19.020, 29.140) 
5. Title, number of pages and language(s) of the notified document:  Energy Conservation 
Program: Test Procedures for Light-Emitting Diode Lamps (20 pages, English)     
6. Description of content:  The U.S. Department of Energy (DOE) proposes to establish test 
procedures for light-emitting diode (LED) lamps to support implementation of labelling 
provisions by the Federal Trade Commission (FTC) established under the Energy Policy and 
Conservation Act (EPCA). The proposed test pr ocedures define methods for measuring the 
lumen output, input power, and relative spectral distribution (to determine correlated color 
temperature, or CCT) of LED lamps. Further, th e proposed test procedures define methods for 
measuring the lumen maintenance of the LED source (the component of the LED lamp that produces light) to project the rate d lifetime of LED lamps. The rated lifetime of the LED lamp 
is the time required for the LED source compone nt of the lamp to reach lumen maintenance 
of 70 percent (that is, 70 percent of initial lig ht output). After reviewing available industry 
standards for determining the lumen output, input power, CCT, and rated lifetime, as well as 
current best practices and technological developments, DOE tentatively identified that the test methods described in the relevant Illuminati ng Engineering Society of North America (IES) 
standards are appropriate for developing test procedures for LED lamp s. The proposed test 
procedures are based in large part on I ES standards LM-79-2008, "Approved Method: 
Electrical and Photometric Me asurements of Solid-State Li ghting Products" for determining 
lumen output, input power, and CCT, a nd LM-80-2008, "Approve d Method: Measuring 
Lumen Maintenance of LED Sources" and TM-21-2011, "Projecting Long Term Lumen 
Maintenance of LED Light Source s," for determining rated lifetim e, with some modifications 
as required.  G/TBT/N/USA/698
