Sea-Dog Stainless Steel LED Dome Light - 4" Lens

The Sea-Dog Stainless Steel LED Dome Light with 4" lens (model 400193-1) is a marine-grade interior cabin light engineered for durability in saltwater environments. Constructed from corrosion-resistant 304 stainless steel stamped construction, this LED dome light delivers reliable illumination across fishing boats, cabin cruisers, and coastal vessels where salt spray and moisture pose constant threats to standard fixtures. The 4-inch lens spreads light evenly across cabin spaces, making it a standard choice for both retrofit installations and new build-outs in recreational and commercial marine applications.

The fixture features 18 white LEDs operating at just 0.068 amps at 12 volts, delivering efficient, low-heat illumination with an exceptionally long service life. This minimal power draw is critical for boats relying on battery banks or solar charging systems, where every amp-hour counts on multi-day offshore runs. The LED dome light comes prewired with an integral on/off toggle switch for straightforward installation. Vibration-resistant construction ensures the light maintains performance through heavy seas and rough water conditions without optical degradation or component failure. Surface mounting requires three right-hand fasteners (sold separately), allowing flexible placement in cabin overhead, galley, or head installations.

This light suits weekend anglers upgrading cabin lighting on center consoles and open fishermen, as well as liveaboard boaters and cruising sailors who depend on reliable, low-power cabin illumination in remote anchorages. Maintenance crews on commercial fishing vessels and charter boats also specify Sea-Dog LED dome lights where salt-corrosion resistance and extended service intervals reduce downtime. The combination of stainless steel construction, low electrical demand, and sealed LED design makes replacement cycles infrequent—a practical advantage when servicing a fleet or accessing cabin fixtures in rough conditions.

Sea-Dog has positioned itself as a reliable source of marine hardware for vessels operating in harsh coastal conditions. This 4-inch LED dome light is part of a broader suite of stainless steel fixtures designed to withstand UV exposure, salt spray, and vibration without compromising form or function. For boat owners balancing durability, efficiency, and ease of installation, the Sea-Dog LED dome light represents a proven solution that continues to perform season after season.
