Lunasea Bayonet LED Bulb BA15D - 10-30VDC/1W/75 Lumens - Warm White

The Lunasea Bayonet LED Bulb BA15D is a high-efficiency replacement light designed for 10–30VDC systems requiring warm white output at 75 lumens. This LED bulb delivers the form factor and warm color temperature of traditional incandescent lighting while consuming a fraction of the power—equivalent in output to a 15W halogen bulb but drawing only 1 watt. Built-in buck regulator circuitry ensures stable performance across the full voltage range, making it ideal for marine, RV, aircraft, and off-grid applications where power conservation directly extends runtime and reduces electrical load on batteries or alternators.

The BA15D bayonet base provides secure mechanical fit in standard sockets without adapters. A 360-degree viewing angle ensures even light distribution in enclosed fixtures, eliminating dark spots common in directional LED designs. The rated lifespan exceeds 50,000 hours, translating to decades of service in intermittent-use applications—far outlasting incandescent or halogen alternatives. The warm white color temperature (indicated by the "W" in the part designation) renders colors naturally without the harsh blue tint that some LEDs introduce, making it suitable for both task lighting and ambient applications where color accuracy matters.

This bulb is engineered for demanding environments where reliability under voltage variation is critical. Vehicle electrical systems, marine installations, and portable power setups all experience voltage fluctuation—the internal regulator maintains consistent brightness despite these swings. Users deploying off-grid renewable energy, running extended field operations, or retrofitting older lighting systems benefit from the energy efficiency gains. The compact design allows drop-in replacement in existing fixtures without modification, simplifying upgrades from incandescent technology while maintaining backward compatibility with legacy hardware.
