scope:
ANSI/IES LM-80-15 provides the methods for measurement of luminous flux and color maintenance for LED packages, arrays, and modules.The document covers luminous, radiant, or photon flux maintenance and color maintenance including changes in chromaticity coordinates, peak wavelength, or centroid wavelength versus time.The maintenance characteristics are measured under controlled conditions that allow direct comparison of results obtained at different laboratories.
ANSI/IES LM-80-15 does not provide guidance or make any recommendation regarding predictive estimations or extrapolation for the maintenance characteristics beyond the time duration of the actual measurements.
