2.8 Watt Miniature - T3-1/4 - 5000 Average rated hours - Miniature bayonet base - 55 Volt

Engineered for Long-Term Reliability in Critical Indicators

In industrial and commercial environments, there is no room for equipment downtime caused by a failed indicator light. The Satco 2.8-watt miniature incandescent bulb is engineered specifically for those demanding applications where consistency and longevity are non-negotiable. With a robust 5,000-hour average rated life, this bulb significantly reduces the frequency of maintenance cycles, ensuring your control panels, signal displays, and specialty instrumentation remain functional and visible through heavy-duty use.

This miniature T3-1/4 bulb features a secure BA9s miniature bayonet base, designed to lock firmly into place. This mechanical connection is essential for environments prone to vibration or movement, preventing the bulb from loosening over time—a common failure point in standard screw-in lamps. Operating at 55 volts, it delivers a clear, 360-degree beam spread that ensures status lights are easily visible from any angle, providing immediate visual feedback for operators and technicians.

• Extended Operational Life: The 5,000-hour rating means fewer replacements in hard-to-reach enclosures and sensitive machinery.
• Vibration-Resistant Base: The miniature bayonet (BA9s) design provides a positive lock, making it ideal for moving equipment and industrial workstations.
• Specialized Voltage Compatibility: Optimized for 55V systems, frequently found in specialized power supplies and legacy control hardware.
• Crystal Clear Visibility: A clear glass finish and high-quality C-5 filament design provide sharp, unobstructed light for precise signaling.
• Compact Form Factor: The T3.25 shape fits easily into tight spaces, allowing for high-density indicator arrays without overheating concerns.

Whether you are maintaining a manufacturing plant's control room or restoring specialized vintage electronics, this Satco miniature bulb provides the professional-grade performance required to keep your systems running safely. Its RoHS compliance ensures it meets modern environmental standards while delivering the classic, reliable illumination that incandescent technology is known for.
