Deep Glow is the premier manufacturer of durable underwater lighting for use at commercial and residential waterfront properties. Deep Glow lights illuminate the water around docks and seawalls creating a virtual aquarium that everyone can appreciate. "It's like having the Discovery Channel in your back yard!" Simple to install, they are specially designed to be thrown, dropped or placed in the water by the homeowner or staff and will automatically right themselves on the bottom facing the water’s surface. When the sun goes down the fun starts as the Deep Glow lights illuminate fish and marine life, as well as provide above water illumination for docks, bridges, and piers. The lights improve visibility while returning from boating or fishing at night, while also providing an extra level of security after hours. The lights operate automatically with a timer or photocell, making them conveniently easy to use and enjoy. Additionally, Deep Glow lights are environmentally friendly using less power and providing more illumination than traditional above water dock lights. Patented Deep Glow lights were specially designed for both residential and commercial use and they perform under various settings. From harsh saltwater locations and rough water environments to calm lakes and decorative ponds, our lights consistently provide satisfaction for our customers around all over the world. Deep Glow lights are virtually maintenance free producing heat to combat marine growth and are easy to pull out of the water and clean, if necessary. The replaceable bulbs come in four colors and can be purchased from us directly. And finally, all Deep Glow lights come with a one year warranty.
