Two PLASA Photometrics Standards Available for Public Review

Two draft photometrics standards are available for public review on the PLASA website now until late October. The two standards are BSR E1.25 - 201x, Recommended Basic Conditions For Measuring The Photometric Output Of Stage And Studio Luminaires By Measuring Illumination Levels Produced On A Planar Surface, and BSR E1.41 - 201x, Recommendations for Measuring and Reporting Photometric Performance Data for Entertainment Luminaires Utilizing Solid State Light Sources. They are available for free download at the URL listed below.

BSR E1.25 - 201x, Recommended Basic Conditions For Measuring The Photometric Output Of Stage And Studio Luminaires By Measuring Illumination Levels Produced On A Planar Surface, is a revision of the existing ANSI E1.25 - 2006. It describes the basic conditions for measuring the photometric output of stage and studio luminaries by a variety of testing methods that measure the illumination levels produced by the luminaires on a planar surface. It is available for review through October 31, 2011. The review is over when November 1 starts.

BSR E1.41 - 201x, Recommendations for Measuring and Reporting Photometric Performance Data for Entertainment Luminaires Utilizing Solid State Light Sources, offers recommendations for measuring and reporting the output of LED luminaires used in the live entertainment industry. This industry needs unusually precise color and color rendering characterization, which this document provides. Current methods for luminaire output measurement assume the use of broad-band emitters, which LEDs are not, and do not deal well with characterizing the intensely colored light LEDs can produce. This draft standard is available through October 17, 2011. The review is over when October 18 starts.
