Detailed description

The LUMISHORE SUPRA THX804 underwater LED lighting is a high-intensity through-hull illumination solution designed for sportboats, cruisers, yachts, and superyachts. Featuring advanced Lumishore technology, this system integrates a light module and a compact external electronic driver for reliable performance and extended service life.

Performance and Technical Specifications

The SUPRA THX804 delivers powerful illumination with a total of 30,375 lumens, including 13,500 verified lumens in white mode. It uses a HICOB Array LED configuration, comprising 36 x 10W LEDs for white and 48 x 3W LEDs for blue, offering dual-color capability. Its 110-degree ultra-wide beam ensures broad coverage and underwater halo effects. With a typical lifespan exceeding 50,000 hours, this lighting system is built for longevity. It operates on a 12V/24V DC power supply, with an operating range of 10.5–31 VDC, and a maximum current draw of 8.8A (at 12V) or 4.4A (at 24V), for an average power consumption of 106 W.

Design and Integrated Control

The LUMISHORE SUPRA THX804 is engineered for marine environments, featuring a marine-grade bronze (also listed as marine aluminum bronze) housing and a glass lens, ensuring IP68 water and dust resistance. Its flush-mounted, low-profile design allows seamless integration into the hull. The system offers dynamic lighting effects, including color variation, brightness adjustment, and dual-speed strobe modes. Control is versatile, operating via the SUPRA i-Connect Hub & Switch, compatible MFDs with the optional SUPRA Bridge module, or even via Wi-Fi using the SUPRA Bridge module. This multi-light synchronization capability enhances the visual experience. Compared to basic underwater lighting solutions, the THX804 stands out as a complete system offering superior control flexibility and light output, competing with premium offerings from specialized marine lighting brands thanks to Lumishore technology.

Installation and Reliability

The through-hull installation of the LUMISHORE SUPRA THX804 is designed for robust and permanent integration. It must be mounted on a flat surface (transom or hull side) at a depth of 150–250 mm below the minimum waterline. For optimal results, a spacing of 0.8 to 2 meters between lights is recommended. For wooden, metal, or carbon fiber hulls, an isolation kit is required. Bolt torque must not exceed 3 Nm / 26 in-lbs. Each light comes with a 3m cable and preinstalled connector, while the external driver includes a 1m power cable, with extensions available. All Lumishore products are recommended for DC system bonding via a bonding strap for galvanic protection unless the light is fully immersed fore and aft. The 3-year warranty underscores the manufacturer’s confidence in product durability.

Expert opinion

« LUMISHORE SUPRA THX804 underwater lighting: technical analysis and integration »

The LUMISHORE SUPRA THX804 underwater lighting, featuring Lumishore technology, is a relevant option for boat owners, from sports boats to superyachts, looking to optimize the aesthetics and functionality of their vessel at night. Its uses are multiple: it enhances the hull’s appearance when moored, improves visibility around the vessel for safety reasons, and can even attract marine life for observation.

In terms of installation, the THX804’s through-hull system requires rigorous planning and professional execution. The need to drill through the hull and adhere to precise depths and spacing (150–250 mm below the waterline, 0.8–2 m between lights) calls for marine mechanical expertise. The location of the external controller in a dry, ventilated area is also critical for the system’s longevity. Note that for hulls made of wood, metal, or carbon fiber, an isolation kit is mandatory to prevent galvanic corrosion.

This model stands out for its high luminous output (13,500 verified lumens in white) and its two-color capability (blue and white) with dynamic effects. This flexibility is an advantage over simpler single-color lighting systems. Possible integration with compatible MFDs via the SUPRA Bridge module (including Garmin MFDs) provides a centralized and intuitive control interface—a clear benefit for vessels already equipped with a Garmin ecosystem. However, this advanced integration requires an optional module, which must be factored into the budget and installation complexity.

In terms of limitations, while the THX804 is versatile, it is not suited to curved hull surfaces. The need for qualified professional installation, both for mechanical and electrical aspects, makes this product a choice for those prioritizing performance and integration and willing to invest in meticulous implementation. It is essential to respect the torque values to avoid damaging the hull or the lighting.
