18.8 Watt miniature - S8 - 300 Average rated hours - Bayonet Single Contact Base - 28 Volt

Reliable Illumination for High-Performance 28V Systems

When your equipment operates on a specialized 28-volt system, off-the-shelf bulbs simply won't cut it. This SATCO S8 miniature incandescent lamp is engineered specifically for heavy-duty applications where reliability is non-negotiable. Whether you are maintaining a private aircraft, upgrading marine cabin fixtures, or servicing industrial machinery, this 18.8-watt bulb provides the precise, clear light output required for safety and functionality.

The S8 shape combined with a clear finish ensures maximum light transmission, delivering 21 lumens of warm, traditional light exactly where you need it. Designed with a C-2V filament, it stands up to the rigors of specialized electrical environments, offering a consistent performance that lower-quality alternatives cannot match.

Secure Fit for High-Vibration Environments

One of the biggest challenges in aviation and marine lighting is vibration. This miniature bulb features a Single Contact Bayonet (BA15s) base, which provides a secure, "twist-and-lock" connection. This mechanical interface ensures the bulb stays firmly seated even in turbulent conditions or high-vibration engine compartments, preventing flickers or premature failure caused by loose connections.

• Aviation & Marine Ready: Specifically designed for 28V systems common in aircraft interiors, cockpits, and nautical vessels.
• Industrial Durability: Ideal for use in heavy equipment control panels and indicator lights where 24-28V DC power is standard.
• Vibration Resistant: The BA15s bayonet base locks into place, making it perfect for moving vehicles and machinery.
• Crystal Clear Visibility: The clear glass housing allows for 360 degrees of unobstructed light, essential for reading gauges or navigating tight spaces.
• Efficient Replacement: Rated for 300 hours of specialized service, providing a reliable maintenance cycle for critical equipment.

Don't let a minor component compromise your operations. By choosing SATCO's proven incandescent technology, you ensure that your indicators, utility lights, and instrument panels remain bright and functional. Keep a few spares in your maintenance kit to ensure you're never left in the dark during your next inspection or voyage.
