Do room lights, put off that much heat? I remember being in grade school, when it was hot outside, the teacher would turn the lights off. Claiming, it would make the room cooler. Why? How much heat does lighting actually put off, anyhow?

Best Answer

The wattage rating tells you the heat output. Flourescents used in many school put out virtually no heat, but the ballasts that operate them put out quite a bit. Not enough to prove her point though, sorry.

• Yes it does. Depending on the wattage of the light.
• Even though it doesn%26#039;t do anything I still like it when the lights are off.
• depends on what type of lights ur talking about...because school lights actually believe it or not put off about 30 mintues on 80 degrees....so ya
• it really depends on the wattage, fluro lights don%26#039;t do it, but thoses common round ones give a lot off heat off.
• It depends on the type of bulb your using. The incandescent one produces more heat than the fluorenscence tube type. Electrical appliances
• I think it%26#039;s more psychological.
