The NiteLighter Ultra Underwater Lighting System easily installs on any inground pool! Now you can enjoy your pool after dark with this high intensity lighting — and there's no drilling or electrical work required! Just install our in-ground pool light at the desired location using its adjustable poolside mounting bracket. The 50-foot cord easily stretches across the length of your deck and is protected by a low profile concrete-colored conduit, so you won't trip over it. Extra features include an internal timer, for automatic shut-off after 3 or 6 hours, as well as a 3-color snap-on lens kit. Larger pools may need additional kits. The 12-volt, 50-watt transformer is U.L.-listed.
