This document 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. Therefore, different test methods and forms of presentation may be used. It should be noted that laser systems and scenic projectors are not covered by this document.
