Overview

The Lumishore 010-04503-00 is an ECLIPSE SMX24 surface-mount underwater LED light that produces a white wash behind the boat. It runs on 12V DC only (10.5 to 15 V DC) and outputs 3,100 fixture lumens in a 90 degree beam, which helps create a wide pool of light close to the transom or hull side.

It carries an IP68 water-ingress rating for continuous underwater mounting and sits close to the hull with a 70 mm light face and a 17 mm housing profile. Power is a straightforward two-wire connection with an integrated driver, and the attached 2 m cable is sized for a clean run to a switch, breaker, or lighting control location.

Key features

• White output rated at 3,100 fixture lumens with a 90 degree beam.
• IP68-rated housing for permanent underwater mounting.
• 12V DC only supply range of 10.5 to 15 V DC; max current draw 2.5 A at 12V.
• Two-wire hookup with integrated driver (red positive, black ground).
• Each light should be individually fused with a 4 A fuse.
• Marine bronze body with a borosilicate glass lens.
• 70 mm face diameter with a 17 mm housing profile for low-protrusion surface mounting.
• 2 m attached power cable; extensions are possible with the correct gauge to manage voltage drop.
• Specified for vessels up to 7.5 m (25 ft); an isolation kit must be used on conductive hull materials.
• Works from a standard on/off switch and supports dimming and zone control when used with an ECLIPSE Command Center.

What’s included

• Surface-mount underwater LED light with attached 2 m cable.
• Three marine bronze mounting screws.

Installation and setup

Plan the mounting position so the light sits on a flat surface with clear access inside the hull for the cable run. A common placement is 100 to 300 mm (4 to 12 in) below the minimum load waterline on the transom or along the hull side. Avoid areas near exhaust outlets or other heat sources.

Installation requires a cable pass-through hole and pilot holes for the mounting screws. The cable hole is intended to be recessed so the cable gland seats properly and the light sits flush; the cable pass-through uses a 13.5 mm (17/32 in) hole size. Use a marine sealant suitable for below-the-waterline hardware, and allow full cure time before the boat goes back in the water.

Electrical and control

This light is for 12V DC systems only. Wire it with an inline fuse per light (4 A) and keep all connections waterproof. If the cable needs to be extended, use an appropriate conductor size for the run length and load so voltage drop stays low, especially on longer stern-to-panel runs.

Control can be as simple as an on/off switch, which is a practical setup for a single transom light. When integrated with an ECLIPSE Command Center, the same light can be managed with additional control functions such as dimming and zone control.

Compatibility and fit

The light is specified for use on vessels up to 7.5 m (25 ft) and can be installed on common hull materials. On conductive hulls, an isolation kit is required as part of the installation approach. Bonding is not required for the light itself, but good practice still applies for the rest of the vessel’s DC system and corrosion management plan.

Use cases on board

White underwater lighting is often used to illuminate the stern area while rafting up, sitting at anchor, or working around the swim platform after dark. This size and electrical draw tend to match smaller boats that want underwater illumination without committing to large cutouts or higher-current lighting circuits.

Maintenance and care

Rinse the lens and housing after saltwater use and inspect the sealant line during routine haul-outs or stern-service work. Clean with mild soap and water and avoid harsh solvents that can affect seals and finishes.
