Detailed description

The Garmin Lumishore EOS THX1604 is a high-intensity underwater thru-hull light designed for recreational boaters and yacht owners seeking a discreet and high-performance lighting solution. This model stands out for its integration with Lumishore’s EOS systems, offering full-spectrum RGB (RGBW) color options. Positioned as a high-end fixed lighting solution, it provides an alternative to surface-mounted models while ensuring a flush aesthetic.

Luminous Performance and Color Options

The THX1604 EOS is available in RGB (full-spectrum) version delivering 17,500 lumens, providing flexibility to create various underwater ambiances. With an ultra-wide 110° beam angle, it produces an extended halo effect, surpassing many competing lights that often feature narrower angles, concentrating light in a more limited area.

Robust Design and Thru-Hull Installation

Built for marine durability, the light features a marine-grade bronze body and a borosilicate glass lens, achieving an IP68 ingress protection rating. This ensures complete resistance to dust and prolonged immersion. The thru-hull installation requires a standard 1-inch (25.4 mm) fitting. The THX1604 is specifically designed for GRP hulls but can be adapted to wood, metal, or carbon fiber hulls with an insulation kit. It must be installed between 150 and 250 mm below the minimum waterline and spaced 0.8 to 2 meters apart for optimal performance.

Advanced Integration and Control

This light operates on 24 V (20–31 VDC range) with a maximum current draw of 6.5 A and an average power consumption of 156 W. It is controlled via an EOS-LUX control center or directly from a compatible multifunction display (MFD) or an optional Lumishore display, offering a uniform and centralized user experience similar to systems provided by Raymarine or B&G for their own lighting ranges. The data wiring is plug-and-play for RGB models, and the power connection requires a simple two-wire setup, simplifying integration into existing systems.

« Technical analysis of the Garmin Lumishore THX1604 EOS underwater through-hull light »

The Garmin Lumishore THX1604 EOS underwater floodlight is a premium choice for cruising boats and yachts prioritizing discrete integration and high light output. Unlike surface-mounted models, its through-hull installation ensures a flush finish, reducing drag and delivering a clean aesthetic particularly suited to modern hulls. Its external driver, standard on THX models, simplifies electrical installation and maintenance. Control via EOS-LUX control centers or a compatible MFD allows seamless synchronization with other Garmin or Lumishore equipment, providing a consistent user experience.

For optimal installation, strict adherence to recommended depths and spacing (150–250mm below the waterline, 0.8–2m between lights) is essential to achieve the advertised 110° beam angle halo effect. While robust with its bronze housing, careful preparation of the hull through-hull and watertight sealing during installation are critical. For hulls other than GRP (wood, metal, carbon), use of an isolation kit is mandatory to prevent galvanic corrosion. This model suits owners seeking a long-term, integrated solution capable of transforming their vessel’s appearance at anchor or alongside without compromising performance or aesthetics. It is less suited to quick or temporary installations, requiring professional planning and execution.

What type of installation is required for the Garmin SUPRA THX1604 EOS transducer?

The Garmin SUPRA THX1604 EOS transducer is a thru-hull model. It is designed for an integrated installation that provides a flush-mounted aesthetic on the boat's hull.

On which hull types can the THX1604 EOS underwater light be installed?

The underwater light can be installed on GRP hulls (fiberglass). For wooden, metal, or carbon fiber hulls, an isolation kit will be required.

What is the recommended installation depth for the underwater light?

For optimal performance, the underwater light must be installed between 150 and 250 mm (6 to 10 inches) below the boat’s minimum waterline.

What is the ideal distance between multiple THX1604 EOS floodlights for optimal lighting?

To achieve the best lighting results, install the floodlights at a distance of between 0.8 metres (2.5 feet) and 2 metres (6.5 feet) apart.

What safety precautions must be taken when installing the spotlight?

Several precautions are essential:

Always ensure the vessel’s power source and battery are disconnected or isolated before installation.Electrical and mechanical installation must be performed by a qualified professional.Use an appropriate fuse or circuit breaker to protect the entire system.Never attempt to install or remove the spotlight when the boat is in the water.The spotlight must not be exposed to temperatures exceeding 65°C (150°F), such as near hot engine components or exhaust emissions.

Where should the THX1604 EOS spotlight be mounted on the boat?

The spotlight must be mounted on a flat (non-curved) surface of the hull. Installation is only possible on the transom or the sides of the hull.
