This 12V LED pool light provides color-changing illumination for in-ground pools, spas, fountains, ponds, and similar water features. The 40W RGBW fixture measures approximately 9.8 in. in diameter by 3.9 in. deep and is designed for use in standard 10 in. wet wall niches or direct installation without a niche, as noted by the manufacturer. The light is fully submersible and carries an IP68 waterproof rating, using potting and integrated sealing technology to help resist leaks, corrosion, and rust. The unit operates on a low-voltage 12V system and includes a 50 ft power cable that should not be cut. It comes with an external RGBW controller and a handheld remote so you can adjust colors and modes, or change effects by cycling the power. RGBW LEDs provide multiple color options, including flashing, jump change, single-color, and off modes, to suit different applications. The durable ABS lampshade is built for underwater use. When operating the light, it should be submerged in water for proper cooling and service life. This light is suitable for both indoor and outdoor aquatic environments where a low-voltage, submersible fixture is required. Color: Clear.
