Standards Development for Solid-State Lighting -

http://www1.eere.energy.gov/buildings/ssl/standards.html

To accelerate the development and implementation of needed standards for solid-state lighting products, DOE works closely with a network of standards-setting organizations and offers technical assistance and support.

Since 2006, DOE has hosted ongoing workshops to convene the key standards organizations and foster greater coordination and collaboration among related efforts. Attendees provide updates on progress as well as input on potential additional standards needed. Combined ANSI/IES meetings and working group conference calls have resulted in significant progress.
