Is good i got 2 of these lights for my 150 gallon fish tank they both cover about 3 feet of the tank and the tanks 30 height by 72 long by 18 wide i have only had them one day and i really like the way they look for the money you get what you get the way they sit on top of the clear plastic roofing shines bright through it only draw back is you have to be right up next to the things for it to work right which means if you want it to strobe in sequence you need both the remotes at the same time to change them the white is a little off but thats ok i am more or less using these lights for filler lights i have a 48 inch satellite bar that i plan to put on it in the middle after about 45 minutes of constantly messing with it the controller started to act up a little bit i unplug them and they both reset honestly id like to get a few years out of them at least i will update if anything changes with them my advise is get them lights up my backyard roughly 30ft away
