The AL UWL404 SM Underwater Boat Light is a high-performance lighting solution specially designed for boats, yachts, sailboats, and docks. This product, with an IP68 protection rating, is resistant to vibrations and impacts while the boat is in motion. The polycarbonate lens is resistant to breakage. The reflectors in the polycarbonate lens increase light dispersion, providing higher illumination. The patented thermal resin body, equivalent to aluminum in thermal conductivity, ensures the LEDs maintain stable temperatures and extends the product's lifespan. It provides powerful illumination with 36W light output. This light operates within a wide voltage range of 10-30V DC. The product includes a 2-meter, 2X0.50 RNF cable. The package contains 1 underwater boat light, 4 mounting screws, and 1 user manual. Installation must be done below the water surface; otherwise, it will not function properly in the long term, and the warranty will not be valid. Installation Instructions: For cable mounting, drill the cable hole and screw holes with a drill, then apply SIKA sealant and adhesive only to the drilled holes and mount. Do not tighten the screws with a power screwdriver. Please tighten by hand to ensure proper installation. If SIKA is applied around the product and the edges are sealed, water will not enter the back of the product, and the cooling body will not be active. This will shorten the product's lifespan.
