I am a part time stripper in need of some technical lighting advice. Panda has to pay his bills.
Imagine a dark room with absolutely no light. I want light to come from the ceiling and fall on the floor like a torch beam. So the light bulb does not light up the whole room just the general area where the light beam hits the floor.
I tried using a light bulb which has silver backing and the package said that the light beam would make a 50° light cone. It is bit too wide and the bulb ends up lighting up the whole room!
