The Norman Lamps 8GH409570-28 is a 50W halogen aircraft signal lamp designed for 28V DC electrical systems commonly found in commercial and business aviation platforms. Built in a compact T4 tubular form factor with an overall length of 43mm and a 10.5mm glass envelope diameter, this halogen lamp is engineered to fit precisely within the signal light assemblies it was designed for, including those on the Bombardier Challenger 300, Bombardier Global Express 700, and Pilatus PC-12.

Operating at 28V and drawing 1.79A of current, the lamp delivers 1000 lumens of output at a color temperature of 4200K, producing a crisp, neutral-white light characteristic of aviation halogen sources. The CC-8 axial filament configuration ensures consistent, omnidirectional illumination across a full 360-degree viewing angle, which is critical for signal visibility in demanding airborne environments.

The special bi-pin base provides secure, indexed seating in compatible lamp holders, and the lamp is dimmable for applications where variable intensity control is required. With a rated average life of 1000 hours and a quartz halogen construction, the 8GH409570-28 delivers reliable service over its operational lifespan. Each lamp is manufactured to exacting industry and military specifications, with physical, electrical, and optical tolerances meeting aviation standards. Every Norman Lamps aircraft halogen lamp is pre-tested and fully inspected before distribution.
