I have an Odyssea fixture that looks exactly like the one you are looking at. Personally I think you should not buy it. I've had mine for about a year now and haven't had any problems with it, only a bad switch in the beginning. I bought it because of a couple reasons, 1- I was a newbie and didn't know what I was doing, the fixture looked nice so I bought it, and 2- It was cheap. I think you should save and buy T5's or better. Right now I'm looking for lighting, I should've done this to begin with. You actually save money by going a bit more expensive in the beginning. The bulbs on the T5's don't have to be replaced as often as the PC's. And if in the future you want to do corals, your chances are a lot better with a different type of lighting than this one.
Like I said, I haven't had a problem with mine but if I would've spent a bit more in the beginning I think I would've seen better results and saved in the long run. I have a canopy on my tank and my temperature only fluctuates less than one degree. I have not seen any heats issues with mine.
