NEMA Announces Reaffirmed ANSI C78.1431 American National Standard for Electric Lamps

The National Electrical Manufacturers Association (NEMA) announced that ANSI Accredited Standards Committee C78 reaffirmed ANSI C78.1431 American National Standard for Electric Lamps—Slide Projector Lamps, Condensing, Dichroic, Two-inch (51 mm), Integral Reflector, Rim Reference Tungsten-Halogen Lamps with GY 5.3 Bases. This standard consolidates the lamps commonly used for slide projectors into a single standard. The lamps contained in this standard are not to be considered as interchangeable—they will all fit the common socket used for these lamps. 

NEMA’s Lighting Systems Division, as secretariat of ANSI’s ASC C78 for Electric Lamps, is looking for industry experts in the User and General Interest categories to participate in standards development activities. Contact NEMA at if you are interested. Please indicate your interest category and your area of expertise.

ANSI C78.1431-1997 (R2016) is available in hard copy or as an electronic download for $57 on the NEMA website.
