The Norman Lamps 1383 is a 20W incandescent miniature R12 reflector bulb rated at 13V with a BA15S single contact bayonet base. It delivers 240 lumens of warm, frosted light at approximately 2850K and is engineered for dependable performance in low-voltage lighting systems. The R12 blown reflector shape measures 2.63 inches in length and 1.50 inches in diameter, providing a compact form factor suited to space-constrained fixtures. This incandescent bulb produces a flood beam spread, making it well-suited for even, broad illumination within its target applications. The 1383 is fully dimmable, offering flexibility for installations where adjustable light levels are required. With a rated life of 300 hours, it is designed as a direct replacement lamp for elevator cab lighting, RV interiors, marine cabins, aircraft reading lights, and automotive or specialty fixture applications that call for a 13V incandescent R12 source. An LED upgrade alternative is available as model LED-1383-W for installations seeking improved energy efficiency and extended lamp life.
