IES Approved Method for Electrical & Photometric Measurements of High Power LEDs
This document describes the procedures to be followed and precautions to be observed in performing accurate measurements of total luminous flux, total radiant flux (optical power), total photon flux, electrical power, luminous efficacy, color quantities, and wavelength characteristics of high-power light emitting diodes (LEDs) including white LEDs as well as single color LEDs. This document covers LED packages (defined in ANSI/IES RP-16-10) including those with multiple chips and remote-phosphor LED packages. This document covers measurement under pulse operation as well as steady DC operation of LEDs, and in all cases, the thermal condition of LEDs refers to their junction temperature. The approved methods apply to laboratory measurements.
 
This document does not cover LED arrays or modules, nor LED lighting products; it does not cover AC driven LEDs, and does not apply to measurements in LED manufacturer’s production control nor relative measurements of LED thermal characteristics.
