Abstract
An underwater dock light having an internal water cooling system formed from primary, secondary, tertiary, and quaternary mounting surfaces forming a chamber. Each of the mounting surfaces are each in thermal communication with a light emitting unit generating heat. LED circuit boards are mounted at an angle to produce a large diameter of light in the surrounding water. A light bifurcating structure causes a central portion of light to be a different color than the perimeter. The transparent lens has an opening and a latching structure configured to connect the transparent lens to the end of the transparent cover. A tire valve stem is located on the underwater light and is capable of removing or filling the underwater light with a gas. Antifouling circuitry automatically cycles the underwater light on and off multiple times during periods of non-use. Smart circuitry communicates and accepts commands by a user.
