The Norman Lamps 1987 is a 28V 150W quartz halogen aircraft navigation bulb engineered for demanding aviation lighting applications. Built in the compact T4 tubular shape with a 0.50 in. diameter, this halogen lamp delivers high-intensity output in a small envelope suited for navigation, cockpit, and aircraft exterior lighting systems. The double contact BA15D bayonet base ensures a secure, vibration-resistant connection and positive electrical contact in the aircraft environment.

Operating on 28 volts DC at a rated current of 5.36 amps, this halogen bulb is designed for compatibility with standard 28V aircraft electrical systems used across a wide range of fixed-wing aircraft and aviation ground support equipment. The quartz halogen gas fill maintains consistent lumen output and filament temperature throughout the rated life of the lamp. A CC-8 coiled-coil filament construction provides added mechanical rigidity, making the lamp well suited to the vibration and thermal cycling conditions inherent in aerospace service.

With an average rated life of 2000 life hours, the Norman Lamps 1987 offers extended service intervals compared to standard variants of this lamp type. The lamp is dimmable, providing flexibility in applications where variable light output is required. It serves as a direct replacement for GE-1987 and ML-1987, and is sold individually for maintenance and replacement use. A full case of 10 units is available for fleet and facility stock.
