This 10 in. 40W RGBW LED pool light is designed for inground swimming pools, spas, fountains, ponds, and aquariums. It fits standard 10 in. large wet niches and can also be installed directly without a niche as noted by the manufacturer. The light uses a low-voltage 12V DC lamp input with a 120V AC power supply for added safety around water. The integrated ABS lampshade housing is sealed to IP68 for underwater use and helps resist rust and corrosion. The fixture measures 9.8 in. L x 9.8 in. W x 3.9 in. H and weighs 9.2 lb. A 50 ft. power cord is included for plug-and-play installation and should not be cut. The RGBW 4-in-1 LEDs offer multiple color modes, including flashing, jump change, and single colors, with control by the included external RGBW controller and remote or by toggling the power. Tested to UL standards, this light provides a durable, energy-efficient replacement for incandescent pool lighting. Color: Clear.
