I several times read something about a certain projector throwing more or less heat out of itself. I seriously doubt such comments and think this is just a subjective impression. Every bulb produces a neglectible ratio of light compared of the more than 95% of heat that come out of the 150 or 250 W. The projector must get rid of this heat anyhow and throws out hot air accordingly. It doesn't matter it it throws out large amounts of modestly warm or small amounts of burningly hot air. The energy that is added to a rooms air-volume remains the same and so does the actual rise in temperature. A 150 W projector produces nearly 150 W in heat a 250 W projector produces 250 W. The rest is purely subjective. Or am I getting something totally wrong? best regards Stefan - -- Stefan Kahlert, Medizinische Poliklnik der Universitaet Bonn uzs13b@uni-bonn.de
