Philips 7027 (BRL/BCD) - 50W, 12V, G6.35 (50h) bi-pin halogen lamp for projection
The Philips 7027 — ANSI BRL/BCD and LIF A1/220 equivalent—is a low-voltage (12V) reflectorless halogen capsule with a G6.35 socket, designed for projection systems, optics/microscopy, medical and laboratory equipment , as well as entertainment applications. It offers a 50-hour half-life, a CRI of 100 , and a color temperature of 3300K , with a carefully aligned flat filament to ensure a stable and well-defined beam . Its UV-Open quartz capsule and S90 working position facilitate integration into a wide variety of 12V projectors.
