scope:
This Approved Method provides the methods for measurement of luminous flux and color maintenance for LED packages, arrays, and modules. It 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.
This Approved Method does not provide guidance or make any recommendations regarding predictive estimations or extrapolation for the maintenance characteristics beyond the duration of the actual measurements.
