NEMA Publishes American National Standard For Electric Lamps—Single-Ended Metal Halide Lamps
May 2, 2013

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: 70-watt, M98; 70-watt, C98; 95-watt, C90; 100-watt, M90; 200-watt, pulse-start, M136; 320-watt, pulse-start, M154; 350-watt, pulse-start, M131; and 400-watt, pulse-start, M155.
 
View the contents and scope of ANSI/ANSLG C78.43-2013. A hard or electronic copy may be purchased for $488 by visiting www.global.ihs.com, or contacting IHS by phone at 800-854-7179 (U.S. only) or 303-397-7956 (international).
 
NEMA is the association of electrical equipment and medical imaging manufacturers, founded in 1926 and headquartered in Arlington, Virginia. Its member companies manufacture a diverse set of products including power transmission and distribution equipment, lighting systems, factory automation and control systems, and medical diagnostic imaging systems. Worldwide annual sales of NEMA-scope products exceed $120 billion.
