Philips 7158 (FCS) - 150W, 24V, G6.35 bi-pin halogen projection lamp (50h, 3450K)
The Philips 7158 is a low-voltage , reflectorless halogen lamp with a G6.35 base, widely used in projection, microscopy, medical and fiber optic equipment , as well as entertainment applications. It offers 150W at 24V , a color temperature of 3450K , and a CRI of 100 for impeccable color rendering. Its flat filament and UV-Open quartz bulb ensure a stable beam and optimal light collection. With an average lifespan of 50 hours and a luminous flux of 5200 lm , the 7158 is a standard ANSI FCS/LIF A1/216 type reference, with an S90 operating position that facilitates its integration into numerous professional projectors and optical heads.
