The Norman Lamps 4582 is a 450W halogen PAR46 sealed beam lamp engineered for demanding aircraft and helicopter lighting applications. Operating at 28V on the standard aircraft DC bus, this high-intensity flood lamp delivers 20,000 candela of maximum beam candlepower with a wide 55-degree vertical by 50-degree horizontal beam spread, making it well suited for close-proximity illumination tasks such as helicopter search lighting and aircraft auxiliary flood lighting.
The PAR46 sealed beam construction measures 5.75 inches (146mm) in diameter with a depth of 3.75 inches, and the rugged parabolic aluminized reflector housing integrates the halogen light source, reflector, and lens into a single sealed unit. This sealed beam design resists moisture ingress and maintains consistent optical output throughout its service life. The screw terminal base provides a secure, vibration-resistant electrical connection suited to the rigors of airborne operation.
High-output aircraft halogen lamps of this type are rated for a 10-hour service life, a characteristic common to maximum-candlepower aviation sealed beams where extreme intensity is prioritized over longevity. The short rated life reflects the operating demands of high-wattage aircraft lighting rather than a product limitation. Sold as a single lamp, the SB-4582 is a direct replacement for existing PAR46 28V 450W flood-type sealed beam aviation fixtures.
