The Norman Lamps 7387 is a T1 3/4 (T1.75) miniature incandescent bulb designed for low-voltage indicator, instrument panel, and avionics lighting applications requiring a 28V supply. Operating at 28V and 0.04A with a rated wattage of 1.13W, this compact tubular lamp delivers 0.30 mscp of light output and carries an impressive 25,000 life hour rating, making it well suited for installations where longevity and reduced maintenance are critical priorities. The lamp features a C-2F filament construction, which is a coiled-coil filament design associated with improved efficiency and mechanical stability in miniature incandescent lamps. The miniature 2-pin bi-pin base (G3.17) uses a 0.125 in. pin spacing, ensuring direct compatibility with standard 7387-type sockets. The T1.75 tubular bulb envelope measures 0.875 in. in overall length and 0.23 in. in diameter, making it one of the smallest tubular lamp formats available and ideal for space-constrained panel and indicator applications. This lamp is a direct replacement for the CM7387 and is compatible with a wide range of equivalent part numbers used across instrumentation, avionics, and industrial indicator lighting. As an incandescent lamp operating below 30V, it is inherently dimmable and compatible with standard low-voltage dimming circuits. The clear envelope allows full light output to reach diffusers, lenses, or indicator caps without additional light loss. Available individually, with a full case quantity of 10 units.
