AI summary

A pool light assembly includes a water inlet housing having a base with an exterior exposed to the pool water and an enclosed interior including an illuminating structure. A notch is provided in the exterior of the base and extends into the interior for allowing pool water to enter the water inlet housing and be in the proximity of the illuminating structure to act as a cooling element. A sealing structure is included for preventing water from entering electrically active elements, and a retaining member locks and encourages waterproof sealing of the electrically active elements.
