Overview
The Lumishore 010-04518-00 is a SUPRA THX804 thru-hull underwater LED light with an external driver for 10.5 to 31 V DC (12V or 24V) systems. It runs in blue or white, with 13,500 fixture lumens in white and a 110° beam that spreads the light wide under the hull.
The light face measures 110 mm (4.33 in) and sits low outside the hull with an 18 mm (0.70 in) profile. The thru-hull shaft is 140 mm (5.51 in) long and uses a 27 mm (1-1/16 in) shaft cut-out. The housing is marine bronze with a borosilicate glass lens, and the assembly carries an IP68 water-ingress rating for continuous submersion.
Max current draw is 8.8 A at 12V or 4.4 A at 24V, which helps when sizing wiring and circuit protection. This setup is a practical fit for boats where you can access the inside of the transom or hull for the driver, notes on bonding, and clean cable routing.

What’s included
- SUPRA THX804 thru-hull underwater LED light
- External driver
Installation and fit
This is a thru-hull mount, so plan for drilling the 27 mm (1-1/16 in) shaft hole, bedding and sealing the light properly, and having clear access inside the hull for the backing hardware and the external driver. The outside face is kept low to the hull, which helps when mounting on the transom or along the sides where you want a clean profile.
A bonding connection is provided on the light and bonding is required. For metal hull installations, hull isolation sleeves are available.
Electrical and control integration
Mount the external driver in a location that stays dry and allows service access, then route the light’s 3 m (9.8 ft) cable back to it. Control is supported through the SUPRA i-Connect Hub and Switch, and MFD screen control or WiFi control is supported when paired with the required SUPRA Bridge Module and a compatible setup.
Maintenance and care
Keep the lens clear of growth to maintain light output, and wash it with mild soap and water during routine hull cleaning. Avoid abrasive pads on the glass lens, and re-check sealing and cable routing any time the boat is hauled or after hard impacts.
