This is just another version of the standard CCLEDF* that's around the market these days. I have two of these on my 110g display tank, you can read the last few pages of my 110g journal for some recent updates and thoughts about these fixtures. For $150 bucks, if there is a 2-year warranty involved, you're probably not taking too much of a risk....just be aware that since quality control for these fixtures is low, there IS some risk involved.
*CCLEDF= Cheap Chinese LED Fixture.
