IES LM-79-19
Approved Method: Optical and Electrical Measurements of Solid-State Lighting Products
standard by Illuminating Engineering Society, 2019
Full Description
This approved method describes the procedures to be followed and precautions to be observed in performing reproducible accurate measurements of total luminous, radiant, or photon flux; electrical power; system efficacy; luminous, radiant, or photon intensity distribution; and color quantities and/or spectrum of solid-state lighting (SSL) products for illumination purposes, under standard conditions.
This approved method covers LED luminaires, OLED luminaires, integrated LED lamps, integrated OLED lamps, non-integrated LED lamps operated with a driver designated by a manufacturer's identification number or by a defined [ANSI] reference circuit, and LED light engines, all of which will be referred to as
SSL products or device under test (DUT).
SSL products, excluding non-integrated LED lamps, are intended to directly connect to AC main power or to a DC voltage power supply to operate.
