Overview

The Lumishore 010-04467-00 is an interchangeable thru-hull underwater LED light that runs on 10.5-31 V DC and produces single-color white light at 6500K. It throws a wide 110° beam and is rated at 5,100 verified fixture lumens, which helps create a broad light pool rather than a tight spotlight.

This is a two-wire light with the driver built into the unit, so there is no separate driver box to mount. The housing sits close to the hull with an 8 mm profile and uses a marine bronze body with a borosilicate glass lens for long-term underwater use.

If you are adding underwater lighting for docking visibility, a swim platform, or evening fishing, this model keeps the wiring simple while still delivering a bright white output.

Key features

• Single-color white output (6500K) with 5,100 verified fixture lumens and a wide 110° beam angle
• 10.5-31 V DC input for 12 V and 24 V systems
• Max current draw: 4.0 A on 12 V and 2.0 A on 24 V
• IP68 water-ingress rating for continuous submersion
• Two-wire connection with a built-in internal driver; on/off control from a standard switch
• Light face diameter is 88 mm with an 8 mm housing height for a low-profile look on the hull
• 57 mm (2.25 in) shaft hole cut-out; 64 mm (2.5 in) when using an isolation sleeve for metal or carbon-fiber hulls
• 3 m (9.8 ft) standard light cable length
• Marine bronze body with a borosilicate glass lens

Compatibility and fit

Plan around the hull cut-out and the inside clearance before you drill. The shaft hole cut-out is 57 mm (2.25 in) in standard installations, and the light face is 88 mm across. The shaft length is 136 mm, and a bonding connection is provided on the light because bonding is required.

For metal hulls or carbon-fiber builds, an isolation sleeve is used between the fitting and hull, and the recommended hole size increases to 64 mm (2.5 in). Make sure you have unrestricted access inside the hull so you can tighten the locking hardware and route the cable without strain.

Installation and setup

Install on a flat section of the hull where the light can sit flush. A common placement is 4 to 12 inches (100 to 300 mm) below the minimum loaded waterline, while keeping clear of exhaust outlets and other heat sources. When installing three or more lights, spacing of about 2.5 to 3 feet between lights helps keep the light pool consistent along the transom or hull side.

After drilling, seal any exposed core material inside the hole to prevent water intrusion into the laminate. Use a marine sealant around the thru-hull seat and shaft, and allow full cure time before final tightening.

Electrical and system integration

Wiring is straightforward: red is positive DC and black is ground. Each light should be individually protected with a fuse or breaker sized at 6 A for 12 V systems or 4 A for 24 V systems. All splices and connections should be made waterproof and supported so vibration does not work the wiring loose over time.

The cable can be extended when needed; choose the wire gauge so voltage drop stays under control over the full run, especially on longer transom-to-battery routes. Built-in protections such as reverse polarity protection and soft-start electronics help the light behave well on real boats where battery voltage can swing and loads come on and off.

Maintenance and care

Check the lens and housing regularly for marine growth, especially if the boat stays in the water. A soft cloth or a soft bristled brush is the right approach. Avoid abrasive pads, solvent-based cleaners, acids, alkalis, pressure washing, or sandblasting since those can damage the lens and sealing surfaces.

If the light is covered during maintenance or bottom work, keep it switched off until the covers are removed.
