DJW - Check out this thread - Sealed Room 3lbs/light. He's got the same light concentration as you are contemplating - except he's doing an 8'x8' area. This isn't exactly the same kind of grow you are talking about, but Tranoble seems to have his shit dialed in pretty tight and you might get some good ideas from the thread.
