Lunasea MR16 LED Light Bulb - 12V AC/DC/3W/290 Lumens - Warm White

The Lunasea MR16 LED Light Bulb – 12V AC/DC/3W/290 Lumens – Warm White is purpose-built for marine vessels where reliable cabin and navigation lighting is non-negotiable. After years running boats of all sizes, I've learned that undersized or inefficient lighting systems compromise safety and comfort when you're on the water after dark. This compact LED bulb replaces traditional halogen MR16 fixtures in your boat's existing 12-volt electrical infrastructure, delivering consistent warm white illumination whether you're anchored in a remote cove or cruising coastal waters.

The 3-watt LED technology produces 290 lumens of warm white output while drawing minimal current from your boat's battery bank—a critical advantage when you're relying on limited reserve power. This bulb operates seamlessly on either AC or DC power at 12 volts, making it compatible with both shore power and onboard battery systems without modification or additional adapters. The MR16 form factor fits directly into existing reflector-style fixtures, reducing installation complexity and eliminating the need for costly rewiring. LED technology generates virtually no heat compared to halogen predecessors, reducing fire risk in tight cabin spaces and improving comfort during long passages.

This bulb is ideal for galley lights, cabin overhead fixtures, and navigational spreader lights where warm white color temperature enhances visibility without creating harsh glare on water or instruments. The efficient power draw makes it particularly valuable for cruising sailors and fishermen operating under battery-only conditions for extended periods. Its compact design—weighing just 0.18 pounds and measuring 4 x 2 x 6 inches—fits into tight mounting spaces found aboard most recreational vessels. Simply swap out your existing MR16 halogen bulb, and you'll immediately notice extended battery life, reduced electrical load, and warmer, more natural illumination throughout your cabin.
