Press release date: Nov 05, 2008
This standard is a proposed revision and consolidation of ANSI C78.1385-1998, .1386-1998, .1387-1998, and ANSLG SR92-2002. It sets forth the physical and electrical requirements for double-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.
ANSI/ANSLG C78.44-2008 has three parts and an annex: Part I covers general requirements and information. Part II contains the lamp drawings of each lamp size. Part III contains the individual lamp double-end data sheets that provide the specific lamp, ballast, and luminaire requirements of the standardized double-ended metal halide lamp type. Annex A contains the design and dimensions of luminaire simulators needed to measure double-ended metal halide lamps.
