Aquaillumination hydra 52 led reef aquarium light.Wifi light. You will need AI app to use properly on your phone. Works great, no issues, was on frag tank for a few years before we moved and in storage ever since. Paid over $600.00 new. What you see, is what you get, light and transformer.These lights have replaceable pucks in the event one led puck starts to go bad. These are the lights that set the industry standard for all other lights........ I WILL SHIP OUT NEXT DAY AFTER AUCTION ENDS..Beautiful light, with programmable spectrum..very powerful. Never dropped, never gotten wet, I take impeccable care of my equipment.
