I bought the 36" 4x39 Solar Xtreme from my LFS last week. The store had a few other brands, but he sold me on this one because it had a timer built in. So not knowing much about it I gave in and bought it. After reading up on it when I got home, I got to be a little uncomfortable with it. I couldn't find a lot of information on it, and the info I did find, wasn't that good. I decided in the morning I was going to go back and exchange it.
I went back to the LFS and after talking to someone else there, he did admit that some of the problems were common, but for the price, the fixture has a lot of features. Looking at the other choices that they had there, I went with the 36" Nova Extreme 4x39. It was a little more, but I've read on countless threads that Nova Extremes are good fixtures, and the sales guy said the same thing.
A few things I've herd about Deep Blue kits are the fixtures smoking, the LEDs shortings out, the ballists burn out quick, and bulbs pop especially with the 48" model. Just the thought of having an electrical problem over water in my apartment was enough for me to return it.
I guess you get what you pay for. The timer, moonlights, and everything seem nice, but I just didnt want to take the risk of something happening when I'm not home.
