Sea-Dog LED Dome Light, White, 4 Inch Surface Mount Cabin Light, 12 Volt

This Sea-Dog LED Dome Light is a surface-mount cabin light built for boat interiors that need reliable, low-heat lighting with a long service life. It runs on 12 volts and draws just 0.068 amps, so it can stay on for extended periods without straining a house battery or generating noticeable heat. The light is prewired with an on/off rocker switch, making it a straightforward swap for an existing dome light or a clean addition to a cabin, head, cockpit locker, or berth area. Inside the fixture are 18 white LEDs, giving even, bright coverage for a fixture this size.

The housing is molded from corrosion-resistant, lightweight plastic finished in white, which resists the salt air and humidity common in marine cabin and below-deck environments. It surface mounts using #8 RH fasteners (fasteners are not included) and measures 4 inches by 5-3/4 inches by 1-5/8 inches, so it fits standard dome light cutouts and mounting patterns used across many boats. Because it is vibration resistant, it holds up to the constant motion and pounding a boat experiences underway, unlike lighter household fixtures. At 0.25 pounds, it is easy to handle during installation and adds negligible weight to a cabin headliner or overhead panel.
