Finally, there is an affordable alternative for LED underwater boat lighting. These High-Intensity LED Underwater Lights are totally waterproof and designed to be used above or below the water line. These lights are great for illuminating your boat's surroundings, transforming your interior for a unique look, or even for attracting bait fish to your boat. A broad flood light effect is created by the engineered optics of the convex light face. Compared to other LED models on the market, this light has a greater light output and a wider aperture.
