Have you taken a look at stink buds system I posted, or have you seen it before? If you ran the 4 1ks you'd have an awesome room pulling huge weight every 3 weeks in your same bedroom size area. I very well may change to his system when I build my next room. My current room I built to maximize the one light I had, and didn't want to run more then one light. His system can be ran well with only 2 1ks, but 3-4 would really maximize the coverage.
