IES Approved Method: Measuring Luminous Flux and Color Maintenance of LED Packages, Arrays and Modul

Print version available end of August 

This document describes the procedures by which LEDs are tested for the luminous (or radiant, or photon) flux maintenance and chromaticity maintenance or wavelength changes over time when operated under controlled environmental and operational conditions. The resulting measurements may be used for comparison of LEDs, and they may be utilized in models that project long-term changes in light output during the life of the LEDs.

The scope within this ANSI/IES LM-80-15 has been expanded to include tests for three types of flux maintenance along with tests for how chromaticity changes over time. LED drive characteristics have been updated to include pulse width modulated current, DC constant voltage and AC regulated voltage drive. The maintenance test duration and measurement interval are no longer specified but rather left for determination according to the intended usage of the data. The reporting section is more specific with regard to the required data. Requirements for thermal measurements have been clarified to reflect industry best practices.
