    Thru-Hull Full Spectrum RGBW Round Fixture Underwater Light - 120 Degree Beam Angle

    The F-Series line of underwater marine lighting fixtures is designed to be mounted at a depth of up to 4.6 m (15 ft) below the water's surface to provide vibrant color and color-changing light in the water. With watertight aluminum bronze housings and silicon bronze hardware, Metro Marine's F-Series luminaires are perfect for marine-based applications such as thru-hull installation on yachts, as well as mounting to docks, sea walls, and for use in fountains and theme park installations. Leveraging Metro's rich legacy of innovation and leadership in optics & LED control technology, the F-THR4-FS-120 introduces a unique LED array to the market with 80 H.O. LEDs per fixture, 74 RGBW and 6 UVC, allowing close adjacent fixture placement where fully mixed, uniform light is important. The close color mixing distance eliminates visible color separation, while integrated UVC emitters provide patented anti-biofouling protection that keeps the lens clean and growth-free, and Metro's patented assembly method prevents condensation from forming inside the fixture.

    The F-THR4-FS-120 is a superior underwater RGBW LED luminaire with 120° optical lensing for lighting mid- to large-scale structures and yachts ranging from 10 m (32 ft) to 30 m (100 ft), with uniform color control and high efficiency.
