I had them. They were good for my zoas, LPS, and I had a anemone split about 6 times under them but I could not get SPS to take off, so I went to AI Sol blues. Don't bother getting the aqua rays. I have a 1/2 round tank so I was thinking it would be easier to place lights in such a weird shaped tank. Search "76 gallon 1/2 round" for my build thread if you would like to so how I had them set up.
