RGB 3-in-1 LED Underwater Fountain Light WB4115R
The WB4115R is a practical, hard-working underwater light designed specifically for fountains, reflecting pools, and in-ground water installations. With its compact round shape and stainless steel finish, it blends neatly into decks and fountain bases while providing strong, even illumination that brings water features to life after dark.
Construction and Build Quality
The light features a solid stainless steel body paired with thick tempered glass for excellent durability and clarity. Multiple mounting ears with clips make secure installation straightforward on concrete or flat surfaces. The sealed design protects the internal RGB 3-in-1 LEDs and drivers from water ingress, supporting long-term submersion. Cable entry is well-gasketed, and the overall build handles typical fountain conditions without fuss.
