IES LM-86-15:2015 Edition

This document provides the method for measurement of luminous flux and color maintenance of remote
phosphor components. The method describes the procedures to be followed and the precautions to be observed in obtaining uniform and reproducible luminous flux and color maintenance measurements under standard operating conditions.

This document does not cover the determination of the performance rating of products, in which individual variations among the products should be considered. This approved method does not provide guidance or make any recommendation regarding sampling, predictive estimations or extrapolation for luminous flux or chromaticity maintenance determined from actual photometric measurements.
