I'm just about to set the tank up and plan on 3 of them.  I'm going to do a mixed reef with SPSs on top.  I like the idea of hanging the lights to keep them out of the way when doing maintenance.  Wondering how high I can go before the spread becomes too much.  I'm going to use diffusers, and happy to add more lights if need be.  
In a perfect world, I'd raise them up around 2'.
Appreciate the help!
