Overview

The Lumishore 010-04358-00 is a SUPRA THX/TIX i-Connect hub kit that combines a junction box and control switch for Lumishore SUPRA THX and TIX underwater lights. It centralizes power distribution and mode control for up to four lights, while handling 10.5 to 31 V DC input for common 12 V and 24 V onboard systems.

Inside the hub, each light output is individually protected with a replaceable blade fuse and has its own status LED, which makes troubleshooting easier when a single fixture or wiring run has an issue. The internal switching uses a built-in relay, and the hub includes a noise filter plus reverse polarity protection.

The enclosure uses an ABS housing and measures 148 mm x 79 mm x 38 mm (not including cable glands). Connections are rated IP68, which suits transom lockers, bilge-adjacent spaces, and other areas where spray and washdowns are common, as long as the hub is mounted where you can still reach it to check LEDs and service fuses.

Key features

• Runs up to 4 SUPRA THX/TIX (DC) underwater lights from one hub
• 10.5 to 31 V DC input range for 12 V and 24 V electrical systems
• Max input current: 40 A; max output per light: 10 A
• Replaceable blade fuse and status LED for each light output
• IP68-rated plug-and-play connections for wet marine mounting areas
• Built-in relay switching, noise filtering, and reverse polarity protection
• Switch-based mode control with white, blue, strobe, synchronized strobe, fade, and synchronized fade
• Expandable system support, with installations documented up to 16 hubs (64 lights) for thru-hull setups

Compatibility and fit

This hub kit is for SUPRA THX and TIX series underwater lights in DC versions. It is the power and control point for the lighting system, not a standalone light.

The hub accepts 10.5 to 31 V DC, but the connected lights still need to match your boat’s system voltage. Some fixtures are 24 V only, so confirm the fixture requirements before wiring a mixed-voltage system.

Installation and wiring notes

Mount the hub where it stays accessible and protected, such as a transom locker, aft bilge area above the waterline, or a service bay close to the light cable runs. Leave clearance to open the cover and replace fuses without removing the box.

Route wiring with drip loops and proper strain relief, and keep power runs tidy to reduce voltage drop on longer transom runs. Even with IP68 connections, avoid placing the hub where it sits in standing water or takes direct, continuous spray.

Control and on-board use

The included switch cycles through light modes and supports synchronized effects across the lights connected to the hub. This setup fits boats running multiple underwater lights where you want one centralized fuse point and simple, repeatable control without opening panels every time a light needs attention.
