Standards Development for Solid-State Lighting
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.
Current Standards
ANSI C78.377-2008, Specifications for the Chromaticity of Solid-State Lighting Products
Specifies recommended chromaticity (color) ranges for white LEDs with various correlated color temperatures (CCTs). Available free as an electronic download. Hard copies can be purchased from the ANSI and NEMA websites.
IES LM-79-2008, Approved Method for the Electrical and Photometric Testing of Solid-State Lighting Devices
Specifies a standard test method for measuring the photometric properties of SSL devices, allowing calculation of luminaire efficacy. Electronic copies may be purchased online through the IES store.
IES LM-80-2008, Approved Method for Measuring Lumen Depreciation of LED Light Sources
Specifies a standard method for measuring the lumen depreciation of LEDs, allowing calculation of LED lifetime. Electronic copies may be purchased online through the IES store.
IES RP-16 Addendum a, Nomenclature and Definitions for Illuminating Engineering
Provides industry-standard definitions for terminology related to solid-state lighting. Electronic copies may be purchased online through the IES store.
