A drop-in LED replacement for Jandy WaterColors and HydroCool pool and spa lights. It threads directly into the standard 1.5 inch nicheless fitting and runs on 12VAC, so it installs exactly like the original Jandy light. No pool drain required. Choose your brightness and cable length at checkout. Select 6W for steps, benches, small spas, and smaller pools, or 12W for full-size pools and maximum output closer to the original. Then pick a 50, 100, or 150 ft cable to reach from your niche to the junction box. Between the two brightness levels and three cable lengths, there is a match across the WaterColors nicheless JLU4C series and the HydroCool lineup. If you need white only- we can custom make those for you. Just send a message. Built to outlast the original: Soft glow diffuser for even lighting with no hot spots Perma-seal resin filled housing engineered against the water intrusion that ends most pool lights early High-efficiency CREE LED chipset that runs cool for years of operation Liquid heat-transfer cooling for sustained brightness Thin-jacket cable that pulls easily through tight conduit without binding 14 RGB Jandy Matched color modes for vivid, programmable lighting Compatible with Jandy Aqualink RS and Jandy WaterColors LED Light Controller JLU4C6W50, JLU4C6W100, JLU4C6W150, JLU4C12W50, JLU4C12W100, JLU4C12W150, Covered by a 2-year warranty against water intrusion and LED failure.
