I do see a small amount of disco ball effect where the light concentrates through the rockwork but it's minimal and I don't even notice it unless I get to staring for a while. I don't run much as far as sps is concerned but I do have a large quantity of lps and zoas/plays. They all seem to love the lighting and some have never looked better.  
I am still yet to run the lights at 100% and even at 80% some of my fish were hesitant to go all the way to the surface for food.  
 
That is all

 Does the ballast get warm? Are they cooled or require cooling
