Haha . . I'll have to take some pictures of the light (maybe I'll even remove some electrical tape for gruesome surgery pics!).
The light was about 6" from the top of the plants for the whole grow. I did burn some side & top leaves, but not too badly.
The grow space is pretty small, I'd say I only used about 4 feet by 3 feet (by 5 feet tall). It has very good ventilation though - I installed an induction fan going into the attic, and there's intake from the eaves of the house. I also used mylar (just ordered online) which I think made a pretty big difference.
