The Norman Lamps 8623 is a special service incandescent miniature bulb designed for precision low-voltage indicator and signal applications. Rated at 28V and 1.12W with a 40mA current draw, this T1 1/4 tubular incandescent lamp is built to exact specifications required by instrumentation, avionics panels, electronic equipment, and specialty signaling fixtures that operate on 28V DC systems. The lamp measures just 0.525 inches in length and 0.168 inches in diameter, making it one of the smallest tubular incandescent lamp forms available, ideal for space-constrained indicator sockets.
The 8623 features a C-2F coiled-coil filament construction and a clear glass envelope, delivering a light output of 0.32 MSCP with a full 360-degree viewing angle. The special knurled brass screw base provides a positive mechanical grip and reliable electrical contact in the socket, resisting loosening from vibration common in instrument panel and equipment environments. With a rated average life of 1,000 hours, this incandescent bulb delivers consistent performance across its service life. The clear finish allows the lamp's natural warm incandescent output to pass unfiltered, making it compatible with colored lens caps and filter assemblies commonly used in indicator systems. This bulb is dimmable and sold as a single piece, with a full case quantity of 10 units available for maintenance and replacement inventory.
