The majority of swimming pools in North America lack pool lighting. Pool lights must be electrically wired and planned for before the pool is constructed. The expense of installation, lights and replacement bulbs are real reasons most pools have no light. FLOlight is the zero wires eco-friendly solution. FLOlight uses the normal water flow to spin a self-container generator to power 8 LED lights. No need to run wires or put in batteries, the FLOlight only requires water flow. All you have to do is simply replace a standard 1 1/2in threaded jet return! Dramatically enhance your viewing enjoyment with the addition of a colored lens kit. Beautifully accent you're pool in whatever way you choose to have the ambiance right for your landscape. Green, red or blue - You set the mood. Kit includes green, red, and blue lights that screw on to your existing FLOlight!
