I plan on placing a Metal Halide 1800 watt bulb 20 inches in front of me (not exactly in front but over my head) - will this produce more heat than I can handle?
Someone said the question was vague so I'm adding details: The purpose of this experiment is to generate 40,000 lux of light in my immediate surroundings (basically to reproduce outside lighting conditions indoors). This is why the bulbs need to be placed so close to me. If I had put it 40 inches away, for example, perhaps there'd be less heat to deal with, but the amount of light reaching me would be cut in half which means I'd need to add more bulbs. With more bulbs I would have more heat and (I guess) run into the same problem?
