On October 10, 2007 the ANSI Board of Standards Review approved as American National Standards two new documents from ESTA's Technical Standards Program: E1.35, Standard for Lens Quality Measurements for Pattern Projecting Luminaires Intended for Entertainment Use, and E1.36, Model Procedure for Permitting the Use of Tungsten-Halogen Incandescent Lamps and Stage and Studio Luminaires in Vendor Exhibit Booths in Convention and Trade Show Exhibition Halls.
They are now available for purchase on The ESTA Foundation website.
ANSI E1.35 - 2007, Standard for Lens Quality Measurements for Pattern Projecting Luminaires Intended for Entertainment Use describes a method for measuring stage and studio luminaire lens quality with particular emphasis on contrast and perceived image quality (sharpness). It also offers a way for presenting these results on a datasheet in a format that is readily understood by a typical end-user and that allows the end-user to directly compare lenses in a meaningful way.
Without this standard, there is no way to describe how clearly a stage lighting instrument projects an image, other than by showing a person with the actual instrument and gobo. Standards exist for projection lenses, but these are not applicable to the lower quality lenses used on stage and studio luminaires. This standard addresses this lack.
The download version of E1.35 is a ZIP file that includes the standard as a PDF and an EPS graphic file of the test pattern described in the standard. The test pattern is presented in three common gobo sizes, but the graphic is scalable. The print version is the standard only.
ANSI E1.36 - 2007, Model Procedure for Permitting the Use of Tungsten-Halogen Incandescent Lamps and Stage and Studio Luminaires in Vendor Exhibit Booths in Convention and Trade Show Exhibition Halls is a model set of procedures that can be used by convention center and trade show exhibition hall staff to mitigate the risks believed by some parties to be associated with the use of tungsten-halogen lamps and stage and studio luminaires in convention centers and trade show exhibition halls and to allow their use.
This standard helps promote the use of the lamps and luminaires in a safe manner.
Both standards were developed by the Photometrics Working Group, part of ESTA's Technical Standards Program
