NEMA Publishes SSL 3-2010 High-Power White LED Binning for General Illumination

NEMA has published SSL 3-2010 High-Power White LED Binning for General Illumination. This marks NEMA’s first solid state lighting (SSL) standard. Produced by NEMA’s Solid State Lighting Section, SSL 3 provides standardized categorization areas (bins) for the colors of “white” light-emitting diodes (LEDs) used for general lighting. LED manufacturers use binning to manage variations in LED performance during mass production. When manufacturers use different binning structures and labeling, LED system integrators and assemblers face unnecessary testing, verification, qualification, and validation processes.  The bin structures established by SSL 3 promote continuity among suppliers. The contents and scope of SSL 3 may be viewed, or a hardcopy or electronic copy purchased for $37, by visiting www.nema.org/stds/ssl3.cfm
