Lunasea MR11 LED Bulb - 10-30VDC/2.2W/140 Lumens - Warm White

The Lunasea MR11 LED Bulb is a purpose-built marine lighting replacement that delivers 140 lumens of warm white output while consuming just 2.2 watts—a dramatic power reduction compared to traditional incandescent MR11 fixtures. Engineered for 10–30VDC systems and compatible with 12V AC applications, this LED bulb eliminates the heat signature and energy drain of older technology, making it the smart choice for vessel owners who demand efficient, cool-running cabin and navigation lighting.

The 120-degree viewing angle provides even light distribution across typical marine cabin spaces and reading areas without hot spots or shadowing. With a rated lifespan of up to 50,000 hours, this bulb outlasts conventional MR11s by a factor of five or more, translating to years of maintenance-free operation in environments where bulb replacement is inconvenient or costly. The warm white color temperature creates a comfortable ambient environment below deck while preserving the energy budget critical to cruising boats relying on battery power or solar charging systems.

This bulb is ideal for cruising sailors, weekend boaters, and offshore fishermen upgrading cabin lighting, saloon fixtures, or task lighting in engine compartments. Anyone managing a marine electrical system with limited alternator capacity or generator hours will appreciate the reduced amp draw—freeing power for navigation electronics, refrigeration, and other essential systems. The MR11 form factor ensures drop-in compatibility with existing fixtures, eliminating costly rewiring or replacement of installed light housings.

Lunasea Lighting specializes in LED solutions engineered specifically for marine electrical architecture, where voltage fluctuations and power constraints differ sharply from shore-based systems. The dual voltage tolerance (10–30VDC plus 12V AC compatibility) reflects real-world marine conditions where battery voltage sags during heavy load demand. This LED bulb represents a direct efficiency upgrade for any vessel already fitted with MR11 housings.
