For my birthday my wife got me one of the original quanta lights. She ended up getting the wrong size so I contacted luca and he was like overly accommodating, at one point, it almost seemed suspicious he was being so nice, but in the end he just wanted me and my wife to be happy . I ended up switching to the quanta PRO reef Crest. After mounting it and having it for a few days, I cant recommend it more. They are very strong for the money/wattage. I've tested a lot of lights and the only reasonable answer is he's powering them with black magic. The ease of use and pre picked color output is amazing. The build quality is outstanding. They do have to be mounted higher than I'm used to and there isn't an easy off the shelf high end Mount, but I think I actually prefer it, the simple brackets that were provided worked perfectly. I probably won't use another light going forward. Can't recommend the light or the company more. The quality of the light and spectrum had my corals responding immediately which I've yet to experience changing lights, something is always ticked off. Every single coral has got that little extra something since I put them up. If anyone is on the fence or looking for lights, especially if you like or are familiar with t5 , this will be an easy transition. Just go for it. I have existing 90watts of lighting that run full power. This single 24 inch bar running at 37 watts doubled my par.... Black magic I tell you.
