Ø94 mm Stainless LED Underwater Light, 10.5W, IP68

The Ø94 mm, 10.5W LED underwater light (model 04707) is designed to deliver professional-grade illumination to the waters around your vessel. Housing four integrated LED modules in a compact array, it generates a powerful light output with a total draw of approximately 10.5 watts. Thanks to the high efficacy of the LEDs, this fixture emits thousands of lumens of bright light, enough to flood the entire transom area and bathe the water several meters out in a luminous glow. The light distribution is wide (roughly 120° beam angle), ensuring a broad coverage without significant drop-offs at the edges.

Housing & Design: Built with a solid marine-grade stainless steel (AISI 316) body, this light offers exceptional strength and durability for prolonged use in seawater. The face is 94 mm in diameter and polished to a mirror finish, providing an attractive look and easy cleaning of marine growth. The unit’s thickness is only 21 mm, allowing it to sit nearly flush once installed – it won’t protrude much, reducing any risk of knock-off during swimming or maneuvering around the stern. The mounting points (four screw holes) are symmetrically arranged for secure attachment to the hull. Rubber gaskets and stainless screws are provided for a watertight installation.

Electrical Characteristics: A standout feature of this model is its wide input voltage range of 8V to 30V DC. This means that even with fluctuations in your boat’s power supply (for instance, voltage drop under load or use on either 12V or 24V systems), the light will remain consistently bright. The built-in driver circuitry regulates current to the LED modules, protecting them from surges and ensuring optimal brightness and longevity. The LEDs are rated for over 50,000 hours of operation, eliminating the need for replacements for many years. Heat dissipation is handled by the metal housing – the stainless steel acts as a heat sink to keep the LEDs running cool, thereby maintaining light output and extending lifespan.

Light Output: By default, the lamp comes with cool white LEDs, which provide the maximum underwater brightness – ideal for illuminating divers, night swimming, or attracting fish and squid at night. Warm white (or even RGB in some configurations) may be available upon request if a softer hue is desired. Regardless of the color temperature, the intensity is substantial – this light ranks among the most powerful in its class, capable of rivaling even larger “docking” floodlights. Boaters can expect a piercing, crystal-clear light beam that greatly enhances the visual appeal and functional visibility around the yacht.

Installation & Usage: Intended for permanent mounting on the transom or bottom of the hull, the Ø94 light requires a small hole for the cable and four small pilot holes for the screws. All necessary gaskets and stainless steel hardware are included. For optimal results, it’s recommended to mount the unit below the waterline at about 20–30 cm (8–12 inches) depth – this maximizes the light reflection in the water and avoids glare on the hull. This model is an excellent choice for large yachts, sport cruisers, charter boats, and even commercial vessels that want to provide impressive underwater illumination for guests or functional purposes. The IP68 rating certifies that the unit is completely watertight – it can remain submerged indefinitely without any water ingress or performance degradation.

In summary, model 04707 offers a combination of high power, reliability, and elegance. It will transform your boat’s nighttime appearance – the water around your stern will shine brilliantly, drawing admiration and creating a magical atmosphere in any marina or cove where you drop anchor.
