The Norman Lamps 1978X is a 100W halogen aircraft navigation bulb engineered for critical aviation lighting applications including aircraft position lights, deck lighting, and airfield systems. Operating at a low 10V with a 10A current draw, this T3 tubular halogen lamp delivers 2,000 lumens of output at a 4200K cool white color temperature, producing the crisp, high-visibility light required in demanding aircraft and airport environments.

Built around a C-8 filament in a gas-filled quartz envelope, the 1978X is vibration resistant and rated for 2,000 life hours, making it well suited to the rigors of flight operations. Its compact T3 tubular form measures 1.97 inches in length and 0.38 inches in diameter, and it features a double end cap base that provides a secure, reliable fit in standard aircraft navigation light fixtures. The 360-degree viewing angle ensures full omnidirectional light distribution, a key requirement for position and navigation lighting.

With a light output of 130 MSCP and full dimmability, the 1978X halogen bulb offers flexible control in applications where brightness adjustment is needed. The lamp carries National Stock Number NSN 6240-00-007-5214 and is manufactured in Japan. It is compatible with cross-reference part numbers GE-1978X and MD-EN2240-1978X, making it a direct replacement for existing fixtures currently using those designations. Sold individually, this halogen aircraft navigation lamp is also available in a case quantity of 10.
