FOREWORD
This Approved Method describes a standard procedure by which entertainment lighting luminaires, specifically designed for use in the theater, TV environment, film studios, or on-location shoots, can be measured.
Entertainment lighting luminaires usually have much narrower beam spreads than other luminaires, such as those covered by IES LM-35, Approved Method for Photometric Testing of Floodlights using HID or Incandescent Filament Lamps.1 Therefore, different test methods and forms of presentation may be used. For example, test data is required in the form of illuminance values on a vertical aiming plane. Data reporting is covered by publication ANSI E1.9- 2007 (R2017), Reporting Photometric Performance Data for Luminaires Used in Entertainment Lighting, developed by the Entertainment Services and Technology Association.2 IES LM-73 is to be used in conjunction with ANSI E1.9.
In 1998, the IES assembled a task force composed of light measurement experts and members of the theater and TV community. This task force was charged with writing an Approved Method for testing entertainment lighting luminaires, resulting in this document.
It should be noted that laser systems and scenic projectors are not covered by this Approved Method.
