it is amazing how much heat is given off by an incandescent bulb. A 40 watt bulb can overcome the cooling done in a refrigerator and make things warm if it does not turn off when the door is closed. That is a lot of heat. If you have several incandescent bulbs in the 60 watt + range you will have some heating in the room.

Depends on the size of the room, air circulation, and the number and sizes of the bulbs. In the case of the refrigerator, you've got a very small box with that 40-watt bulb. But in a 12-foot square room with an 8-foot ceiling, and say two 60-watt bulbs... That's 120 watts, and hardly enough heat output to even notice. If it's a flourescent light, it's even less heat. But if you have a bank of say, ten 60-watt bulbs over the sink in your small bathroom, that'd be noticeable. Plus, it's a lot of wasted electric to leave them on if you're not using the room. An infra-red heat lamp in the bathroom also puts out a lot more heat than light.

Yes. Just not the whole room. It heats up the area of the light bulb only. And by a very small amount.

It depends on the size of the room, if the room is sealed up, and the type of lights you are using, and how many lights there are in the room.

Incandecent lamps put out a lot of heat, and florescent ones put out less heat.

Although the temperature rise of fall would be very small: probably not being able to take it. The psychological value is great, that old saying :"It's better to lite one light, than sit in the dark"

Yea and Yes, but different types of light bulbs put out different types of heat.
