Replacement Halogen Bulb, 450W, 28V, PAR46, Screw Terminal (CR-2)

This high-performance 450-watt halogen sealed beam replacement lamp is engineered as a direct substitute for the Q4681 aircraft landing lamp. Operating at 28 volts with a PAR46 form factor and screw terminal base, this precision-built lamp delivers an intense, concentrated beam with a maximum beam candlepower of 310,000, making it essential for safe aircraft landing and taxiing operations. The quartz halogen construction provides superior brightness and color temperature compared to standard incandescent sealed beams. With a beam spread of approximately 15 degrees, this lamp produces a tight, focused spotlight pattern ideal for cutting through darkness, fog, and adverse weather conditions. Built to meet stringent aviation standards, it is suitable for a wide range of fixed-wing and rotary aircraft applications.
