NEMA’s ANSI C78.43-2017 Standards Focus on Single-Ended Metal Halide Lamps
Press Release Summary:
The National Electrical Manufacturers Association has published NSI C78.43-2017 American National Standard for Electric Lamps. The standards consist of physical and electrical requirements of single-ended metal halide lamps operated on 60 Hz ballasts. The revision includes comprehensive ignitor requirements for LFSW ballasts that are available in Part 1 and two data sheets for 20W-C156 and 250W-C50 metal halide lamps.

Standard for Single-Ended Metal Halide Lamps Includes New Ignitor Requirements and Data Sheets
ROSSLYN, Va., April 19, 2018—The National Electrical Manufacturers Association (NEMA) published ANSI C78.43-2017 American National Standard for Electric Lamps—Single-EndedMetal Halide Lamps. Developed by the ANSI Committee for Electric Lamps, this revision provides physical and electrical requirements for single-ended metal halide lamps that are operated on 60 Hz ballasts, ensuring interchangeability and safety.
“This standard provides electrical requirements for ballasts and ignitors, as well as lamp-related requirements for luminaires. It also includes lamps whose arc tubes are made of quartz or ceramic materials,” said Selmar Dorsey, lead regulatory engineer for Current powered by GE, and chair of the subcommittee that revised C78.43.
Dorsey said that in addition to updated normative references, major changes include:
1) Comprehensive ignitor requirements for electronic low-frequency square wave (LFSW) ballasts are now in Part I
2) Two new lamp data sheets for ceramic metal halide lamps:
a. 20W-C156 with T4.0, T4.5, and MR16 bulb configurations
b. 250W-C50 for use on ballasts designed for high-pressure sodium lamps
ANSI C78.43-2017 is available in hard copy or as an electronic download for $500 on the NEMA website.
