Organization: IES
Publication Date: 28 February 2019
Status: active
Page Count: 35
scope:

This approved method describes the procedures to be followed and precautions to be observed in performing reproducible 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 lightning (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 mains power or to a DC voltage power supply to operate.

This document does not cover SSL products that require external heat sinks, nor does it cover components of SSL products, such as LED packages or LED arrays. This document does not cover housing or luminaires designed for SSL products and sold without a light source (for which relative photometry would typically be used).This document describes test methods for individual SSL products, and does not cover the determination of the performance rating of products, in which individual variations among the products should be considered.
