i used a lot of flood lights to light the entire garage up, forgot the wattage it was pretty high wattage though probly say about 500watts per light i used about 8 of em set em up in different parts of garage and different angles, i could see everything. It turned out fucking awsome though, no runs, no over spray. no miss shots, no cooking of paint, flaking,chipping or any of the results youd get from a heat source being too close, had everything set up just right.
