LM-80-08

LM-80-08 is the Illuminating Engineering Society of North America (IESNA) approved standard for measuring the lumen depreciation of solid-state lighting sources, such as LED packages, modules and arrays.

LM-80-08 testing report will provide luminous flux for a given current over a 6,000 hours period with interval measurements. Luminous flux will be measured under 3 different temperatures: 55ºC, 85ºC and a third temperature to be selected by manufacturer. Besides, the lumen maintenance, the chromaticity shifts over the measured period.
