scope:

This standard specifies performance requirements for various single-ended, doubleended, integral reflector, and PAR tungsten halogen lamps, with rated voltages up to 277V, and used for projection, photographic, (floodlight), special purpose, general lighting service (GLS), and stage-studio lighting applications.

This standard, similar to IEC 60357, provides dimensional and performance information pertinent to general lighting and specialty tungsten halogen lamps used in North America. This information is provided in C78.357 lamp data sheets, by reference to other ANSI tungsten halogen lamp specific standards, or by reference to adopted IEC 60357 lamp data sheets.

This standard is a revision/consolidation of ANSI C78.24-2001, C78.1413-2001, C78.1417-1997, C78.1421-2002, and C78.MR11-2-1997.
