The National Electrical Manufacturers Association (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. Luminous flux and lamp color are not part of this standard.
ANSI/ANSLG C78.43-2013 has three parts:
- Part I covers general requirements and information. It provides normative references and offers brief explanations of the meaning or the application of some of the numerical data given on the individual lamp data sheets in Part III of this standard. It also provides requirements that are common to all metal halide lamp types.
- Part II contains the maximum outline drawings of each lamp size.
- Part III contains individual single-ended lamp data sheets that provide the specific lamp, ballast, and luminaire requirements of each of the standardized single-ended metal halide lamp types.
The 2013 edition features new single-ended lamp data sheets for: 70W M98; 70W C98; 95W C90; 100W, M90; 200W pulse-start M136; 320W pulse-start M154; 350W pulse-start M131; and 400W pulse-start M155.
