ANSI C78.43-2017 pdf free download.American National Standard for Electric Lamps— Single-Ended Metal Halide Lamps
1 Scope
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 data given also provides the
basis for the electrical requirements for ballasts and ignitors, as well as the lamp-related requirements for luminaires. This standard includes lamps whose arc tubes are made of quartz or ceramic materials.Luminous flux and lamp color are not part of this standard.
