yes, that makes sense now that I visualize that .... now to finish designing my box, the 500watt worklight pumps out some trmendous heat so for now I'm switching to a lower watt halogen till I can afford a halide setup (no OHPs handy around here) if I can figure out how to wire up a OHP bulb with no socket(bulbs I can get, the actual projector no ....and shipping on ebay for OHPs is outrageous) ....
