1.12 Watt Miniature - T3-1/4 - 2500 Average rated hours - Miniature bayonet base - 28 Volt

Reliable Illumination for Precision Environments

When operational awareness depends on the clarity of your indicator lights, the SATCO 1.12 Watt T3-1/4 Miniature Bulb provides the consistent performance required for critical systems. Designed specifically for 28-volt applications, this clear incandescent lamp offers a crisp, 360-degree light spread that ensures instrument panels and status signals remain highly visible. Its specialized C-2F filament is engineered to withstand the rigors of professional use, providing a dependable glow exactly where you need it most.

Installation is straightforward and secure thanks to the miniature bayonet (BA9s) base. This design is preferred in environments prone to vibration, as the locking mechanism prevents the bulb from loosening over time—a vital feature for both mobile and industrial machinery. With an average rated life of 2,500 hours, this bulb minimizes maintenance cycles and reduces the need for frequent replacements in hard-to-reach equipment housings.

Versatile Use Cases and Performance Benefits
