Cool, only thing that is garbage is their customer service. I am runnign their pc lights on my 29 gal and the montipora/candy cane/rbta/zoos/shrooms love it. I also have the 175 halide fixture on my 90 and it looks great.
I haven't heard anyone who bought the stuff say it does not work, but I have heard plenty of people call it garbage who never bought it =) Can't beat the $/watt
