SUPRA THX404, through-hull light with controller

The Lumishore SUPRA THX404 is a thru-hull underwater lighting system, designed for demanding vessels such as sports boats, cruisers, yachts, and superyachts. It combines a powerful LED light with a compact electronic driver for discreet and high-performance installation.

The SUPRA THX404 integrates 12 x 10 W LEDs for white lighting (6500K) and 24 x 3 W LEDs for blue lighting. It delivers a luminous output of 8 150 lumens in white mode. Its optics provide an ultra-wide beam angle of 110°, creating an extended halo effect in the water.

The SUPRA THX404 system allows independent control of colors (white and blue), brightness adjustments, as well as strobe and fade modes. All these features can be synchronized for a consistent lighting experience across the entire system.

The typical lifespan of the LEDs integrated in the Lumishore SUPRA THX404 is over 50,000 hours of use.

The Lumishore SUPRA THX404 is suitable for many types and sizes of vessels, including sports boats, cruisers, yachts, and superyachts, particularly for owners preferring a through-hull installation.

Yes, the Lumishore SUPRA THX404 is supplied with an external compact electronic autopilot module, designed to provide reliable and trouble-free operation for many years.

The light must be installed between 150 and 250 mm (6 to 10 inches) below the vessel's minimum waterline for optimal performance.

For optimal lighting results, install the SUPRA THX404 lights between 0.8 meters (2.5 feet) and 2 meters (6.5 feet) apart.

The light must be installed on a flat surface (not curved). Installation is only possible on the transom or on the side of the hull.

Yes, the THX404 can be installed in GRP (glass-reinforced plastic or fiberglass). However, for installations on wooden, metal, or carbon-fiber hulls, an isolation kit is required.

A qualified professional must perform the electrical and mechanical installation of the underwater lighting system. It is recommended to contact Lumishore if in doubt.

Yes, lights must not be exposed to temperatures above 65°C (150°F). They should not be installed near hot engine components or where exhaust gases could be expelled onto the underwater light.

The maximum tightening torque for each mounting bolt must not exceed 3 Nm (26 in-lbs). It is essential to follow the installation instructions precisely.

All Lumishore products must be connected to the DC system via a bonding strap for galvanic protection. This requirement does not apply to lights that are fully submerged at the bow and stern.

No, the 3-metre (10-foot) pre-installed cable on the light module is fitted with a connector and must not be cut or extended directly. Pre-made extension cables are available if needed.

The power cable for the external autopilot module, which is 1 metre (3 feet) long, can be extended using specific Lumishore extension cables (PN: 60-0401). It is important to consult the cable gauge chart to select the appropriate cross-section based on the total length and boat voltage to avoid excessive voltage drop.

The Lumishore SUPRA THX404 system requires a 12 V or 24 V DC power source, typically a battery or an AC/DC power supply, protected by an appropriate fuse or circuit breaker.

Yes, the system can be controlled via a certified Garmin MFD. This requires the use of an Lumi-Link SUPRA Bridge module (PN: 60-0368) connected to the Garmin marine network.

A Lumishore SUPRA system can support a maximum of 16 i-Connect hubs, allowing up to 64 lights to be connected in total.

A Lumishore SUPRA THX lighting system typically consists of multiple Lumishore THX lights, a SUPRA i-Connect hub, and a SUPRA i-Connect switch. A DC (battery) or AC/DC power source is also required.
