I have had a couple of AI Sol Blues going on 6 months now. Love the way the lights look, the programability, color. I have gotten good results with LPS, SPS and soft corals. I have to say that some SPS doesn't do too well under it though.
I get growth out of SPS corals but some of their colors tend to change. I suspect from the lack of some light spectrum (mainly 420nm Actinic, UV, greens and reds). This doesn't happen to all SPS though. I have noticed that any "fuzzy/hairry" SPS like Pocillopora, Milis, Stylos do well under the AI Sols but other Acroporas have changed the colors a bit.
I recently added a couple of T5s to my AI Sols to get some of the "missing" spectrum (

I have to say it has made a noticeble change at least in my Blue Digita which had good growth under the AI Sols but turned brown. Now the whole colony is getting it's "blue/purple" colors back since I added the T5s.
Just to summarize, I think the AI Sol Blues are great light for LPS and Soft corals, but you should pick wisely any SPS you want to grow under it with out any kind of "light spectrum" suplementation.
Good luck
