I bought this light and I hate it. Not only is it a fire hazard, it's a nightmare to program and I am good at these things trust me. Zero stars, good par but the plug for the power gets way too hot, and I am talking about not even after an hour of being on. I know people out there like this light and have had good results, but honestly it is a fire waiting to happen. Unfortunately, I didn't buy it from Amazon rather some Pet nanny website that is horrible with returns. I am going with a Stingray 2 instead, similar PAR and no gimmicks, just on and off and I don't need to worry about reprogramming if the lights go out. I would of gone with a Current USA which I can say after owning several is an amazing light all around, but they don't make lights for a 30" tank. The Hygger won't even turn back on automatically if the power goes out and comes back. I really wanted to like this light, just thought I should share.
