The AAA LED Dome Light – 4″ Surface Mount is a compact 12VDC marine lighting fixture for providing clear, even onboard illumination. Designed for surface mounting, this round marine dome light has an S.S. 304 housing and a patterned lens that helps spread the light across the surrounding area. Its stainless-steel construction makes it a practical choice for marine lighting installations where a durable metal fitting is preferred. With an overall diameter of 137mm and a 122mm lens diameter, it offers a neat, clearly defined lighting point for boat interiors and other onboard spaces.

This boat dome light uses 20 x “2835” 0.2W LEDs in WW configuration and delivers an effective output of 272LM. The LED arrangement is positioned behind the lens to create a broad lighting surface rather than a narrow, focused beam. It is suitable where general cabin or overhead illumination is needed, including spaces where crew members, passengers, or operators need a visible, well-lit area for routine onboard activity. The 12VDC operating voltage supports use in common 12V marine electrical systems, subject to correct installation by the vessel owner or marine electrician.

The surface-mount format makes this LED dome light suitable for fitting directly onto an appropriate flat mounting surface. It may be used as a dome ceiling light in cabins, saloons, berths, galley areas, passageways, wheelhouse spaces, enclosed cockpit areas, and other interior or sheltered onboard locations where a round LED ceiling fixture is required. The stainless-steel outer rim and circular lens also give the fitting a clean, marine-appropriate appearance that can coordinate with stainless hardware and fittings commonly used on boats and yachts.

For buyers replacing an older boat cabin light or specifying lighting for a new build, the AAA LED Dome Light – 4″ Surface Mount provides the key details needed for product selection: S.S. 304 material, 137mm overall diameter, 122mm lens diameter, LED light source, 272LM effective lumen output, and 12VDC operation. This marine dome light is intended for buyers who need a clearly specified round lighting fixture rather than a decorative fixture with unconfirmed extra functions. Check the available mounting area, electrical voltage, and preferred light position before installation.

When comparing LED dome lights for a vessel, confirm the physical dimensions as well as the electrical requirement. This model has a 4-inch product designation, while its supplied measurements are 137mm overall and 122mm across the lens; these dimensions should be checked against the intended fitting position and any existing cut-out, trim, or surrounding hardware. Because it is identified as a surface-mount unit, the light is intended to sit on the mounting surface rather than be specified as a recessed fitting. For a consistent onboard lighting plan, buyers can use this unit in locations that need a matching round marine dome light and a 12VDC LED light source.
