Description

Approved American National StandardThis document provides recommendations for projecting long-term chromaticity coordinate stability of LED light sources using data obtained per ANSI/IES LM-80-15, Approved Method: Measuring Luminous Flux and Color Maintenance of LED Packages, Arrays, and Modules.

This method shall only be used for phosphor converted LEDs with initial chromaticity coordinates that fall within the ranges defined for solid-state lighting products in ANSI/NEMA/ANSLG C78.377-2017.

This method shall not be used to predict chromaticity shifts in excess of Δu’v’ = 0.010.
