2.87 Watt miniature - G4 1/2 - 200 Average rated hours - Miniature Bayonet base - 7 Volt

Dependable Illumination for Precision Indicators

When your equipment relies on clear, consistent signaling, the SATCO 2.87-Watt miniature incandescent bulb provides the exact performance required for low-voltage systems. Designed specifically for 7-volt applications, this G4.5 bulb bridges the gap between specialized electronic requirements and robust physical durability. Whether you are restoring vintage instrumentation, maintaining industrial control panels, or servicing specialized marine equipment, this bulb ensures your status lights remain visible and reliable.

The Miniature Bayonet (BA9s) base is engineered for high-vibration environments. Unlike standard screw-in bulbs that can loosen under mechanical stress, the bayonet mechanism locks the bulb firmly into the socket. This makes it an essential choice for automotive dashboards, heavy machinery, and aerospace indicators where stability is non-negotiable. The clear glass finish combined with the C-2R filament design provides a crisp, omnidirectional 360-degree beam spread, ensuring maximum light transmission through colored lenses or backlit displays.

• Optimized for 7V Systems: Specifically engineered for low-voltage circuits, drawing a precise 0.410 amps for balanced energy use.
• Secure Bayonet Fit: The BA9s base prevents accidental loosening, ensuring a constant electrical connection even in equipment prone to movement.
• Compact G4.5 Profile: The small footprint allows for easy installation in tight internal housings and narrow signal reflectors.
• Instant-On Performance: Traditional incandescent technology provides immediate full brightness without the warm-up time associated with other lamp types.
• Broad Use Cases: Ideal for pilot lights, instrument panels, toy trains, and legacy electronic displays that require a 7-volt power source.
