NEMA Publishes ANSI/ANSLG C78.43

NEMA, on behalf of the American National Standard Lighting Group (ANSLG), published ANSI/ANSLG C78.43, “American National Standard for Electric Lamps - Single-Ended Metal Halide Lamps.” This standard sets forth the physical and electrical requirements for single-ended metal halide lamps operated on 60 Hz ballasts to ensure interchangeability and safety. The standard also provides the basis for electrical requirements for ballasts and ignitors, as well as the lamp-related requirements for luminaires. Also included are lamps whose arc tubes are made of quartz or ceramic materials.
