UNDERSTANDING LM-79 REPORTS output of the lamp(s) and the ballast factor (BF). Once determined, this value is assumed to be unaffected by the choice of lamp or ballast. By contrast, due to their unique thermal and electrical characteristics, no standard test method has been developed to measure the lumen output of

This approved method describes the procedures to be followed and precautions to be observed in performing reproducible measurements of total luminous flux, electrical power, luminous intensity distribution, and chromaticity, of solid-state lighting (SSL) products for illumination purposes, under standard conditions.
7 May 2009 LM-79 requires complete luminaire testing. • Traditionally, photometric evaluation of lighting products is based on separate tests for lamps and luminaires (“relative"). • For SSL products, LED lamps typically cannot be separated from their luminaire because of heat effects (“absolute")
