Scope and Purpose

Most conventional methodology in the entertainment industry for the measurement of the photometric parameters of luminaires is based around an assumption of the use of broad band or full spectrum emitters. The introduction of solid state narrow band and phosphor converted colored emitters, particularly LEDs, has posed a problem for the industry in characterizing luminaires utilizing such emitters. In particular the industry needs methods for measurement which are defined, repeatable, and defensible to allow the manufacturer to produce marketing material and for the user to be able to use the published data for product comparison. This standard is intended to be used for the presentation of photometric data for luminaires employing solid state light sources used in the entertainment and performance industries. This standard defines photometric data that may be presented on documents purporting to accurately describe the photometric performance of these luminaires when producing white light. It also defines photometric data that may be presented for colored emitters.

This standard does not supersede or replace, and should be read in conjunction with, ANSI E1.9 – 2007 (R2023), Reporting Photometric Performance Data for Luminaires Used in Entertainment Lighting.
