ATI are proven lights but consider replacement bulbs cost depending on what you want to keep could be as much as every 6-9 month @ 10x30=300 bucks. Thats a lot of cash. AI and Radions will have the same coverage, don't think that 2 Radions will replace 4 AI's, that's just pipe dream, not gonna happen. Since you are just setting up, I think you should wait till more advanced LED technology surfaces before making your final decision. I am really liking the orphek multi-chip led with multiple colors of led and the new vega by AI. BTW did I mention that you wouldn't need to change any bulbs for a while.
