Abstract
A light assembly combined into a unitary structure with a liquid circulation fitting, such as a water return fitting, for use underwater or above water in a pool, tub, spa, fountain, or similar large liquid container. The combination is well suited for use as a combined underwater light and return water fitting in pools, tubs, or spas, and especially in above-ground pools, and as a combined ornamental light and fountain jet. The unitary structure eliminates the need for more than one hole in the pool wall and thereby simplifies installation and decreases the chance of leaks. The structure provides for both water and air cooling if the light is installed underwater. Furthermore, the structure is connectable to water supply lines of various sizes, and includes a directionally adjustable port to control water returning to the pool or container.
