The Norman Lamps 120PSB is a T2 incandescent miniature bulb rated at 120V and 3W, designed for use in telephone indicator panels, pilot light assemblies, signaling equipment, and other low-current indicator applications that require a compact, reliable line-voltage lamp. It operates at 120V with a draw of just 0.025A and produces 1,200 End Foot Candles of light output through a clear T2 glass envelope, making it well suited for close-proximity indicator and annunciator installations.

The bulb features an ANSI #5 Slide base, also known as the TS5 telephone slide base, which provides secure, tool-free insertion and positive retention in compatible slide-base sockets widely used in telecommunications and industrial control equipment. The CC-7A coiled-coil filament construction contributes to long, consistent lamp life rated at 10,000 life hours, which reduces maintenance frequency in hard-to-reach or panel-mounted installations.

At just 1.10 inches in length and 0.26 inches in diameter, this incandescent miniature bulb fits within extremely space-constrained fixtures and printed circuit board-mounted sockets. As an incandescent lamp, it is fully dimmable and compatible with standard incandescent dimming systems. A direct LED upgrade equivalent, the LED120PSBW-ACDC, is also available for applications where energy savings or extended service life are priorities.
