- cperciva 17y agoit isn't completely obvious that incandescent bulbs are giving off that much heat. All energy ends up as heat eventually. Since indoor lighting only leaks a very small amount of light (unless you've got an excessive number of windows), a 60W lightbulb will contribute to very close to 60W of heating.
- run4yourlives 17y agoSure, but how many 60W bulbs on the ceiling are required to raise the temperature in a room 1 degree. You seem to be suggesting that leaving my lights on all night has a positive environmental impact since it would significantly affect my furnace use. I find that rather unintuitive, although possible; hence, citation required.
- cperciva 17y agoSure, but how many 60W bulbs on the ceiling are required to raise the temperature in a room 1 degree. Look at it this way: To raise the temperature by 1 K, you need to add X Joules of heat to the room, for some value X. Those X Joules can be added by burning approximately X * 9E-7 standard cubic feet of natural gas; by running a 1200 W electric heater for X * 2.3E-7 hours; or by leaving a 60 W light bulb turned on for X * 4.6E-6 hours.
