26、ndensing 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 ma

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 r

Illumination from side pin projection lamps in this stand.ard is typically measured using large screen photometry appraisal with lamps placed in aperture and lens systems that simulate projectors. See Figure

Light from lamps converges and passes through a vertical rectangular aperture and projection lens, and is formed into a vertical rectangular image approximately proportional in size to the aperture.
