Precision Illumination for Portable Reliability

When your portable equipment requires a steady, focused beam, the SATCO 0.74 Watt miniature bulb provides the dependable performance you need. Designed with a B3 1/2 clear glass envelope, this incandescent lamp delivers a crisp light that cuts through darkness, making it an essential component for high-precision tools and handheld devices. The clear finish ensures maximum light output without diffusion, allowing for a directed 360-degree beam spread that illuminates your task with clarity.

Engineered for stability, the Single Contact Mini Flange base (P13.5s) is the standout feature of this bulb. Unlike standard screw-in bulbs, the flange design ensures the lamp sits at the exact focal point of your reflector every time. This precision indexing is vital for maintaining a consistent beam pattern, preventing flickering or misalignment even when your device is subjected to movement or vibration. Operating at 2.47 volts, it is optimized for dual-cell battery configurations, drawing a precise 0.300 amps to balance brightness with energy efficiency.
