The Norman Lamps 4587 is a 250W incandescent PAR36 sealed beam lamp engineered for aircraft taxiing light applications. Operating at 28V, this sealed beam delivers 40,000 candela of intense, focused output to illuminate runways and taxiways during ground operations. The PAR36 sealed beam construction integrates the reflector, lens, and filament into a single, robust unit that withstands the vibration and environmental demands of aviation service. Secured via a screw terminal base, the lamp measures 2.75 inches in depth and is designed for straightforward installation into standard PAR36 aircraft lighting housings. With a rated life of 25 hours — consistent with the high-intensity output demands of this lamp category — the 4587 is a direct-replacement incandescent sealed beam solution for 28V aircraft taxi light systems.
