ANSI C78.1434

Description / Abstract: This standard consolidates previous standards for certain low voltage condensing dichroic-coated integral reflector side pin tungsten halogen projection lamps with GX7.9 bases designed for large screen projection systems and used in 8mm and 16mm projector applications. The lamp types contained in this standard are not to be considered as interchangeable although they may physically fit into systems with GX7.9 lampholders. Photometry performance of each lamp depends upon the photometry appraisal system for which it was designed as well as the system in which the lamp is used. Photometry appraisal and end use systems may or may not be the same.

Condensing integral reflector side pin tungsten halogen projection lamps with GX7.9 bases having the ANSI lamp designations, DNF and EMM, are included in this Standard.
