Electric Lamps - Slide Projector Lamps, Condensing, Dichroic, 1.65-in.(42 mm), Integral Reflector, Rim Reference Tungsten-Halogen Lamps with GX5.3 Bases
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, although physically they will all fit the common GX5.3 sockets. The photometry of each lamp is dependent upon the system for which it was designed and on the system in which it is used. A sample system and representative photometric values are found in the Annex.
