does having the light bulb on effect the temperature of a room much?

Question

i want to know if having a lamp on or the lights on in the ceiling (or anything else that creates light, excluding fire, such as a light bulb) will effect the room temperature much,
making it hotter or is this change hardly noticeable that it seems like nothing had changed?

Answer 1

yeah it does effects the temp. No your room wont go on fire!

Answer 2

How do you feel compared to someone else? We all feel differently. Some of us actually feel light hitting our skin. Others are not so sensitive.

A light bulb adds heat to a room, everyone agrees. The complication comes in when you start to calculate the change in temperature based on that. If there is a cool breeze in the room, there will be very little temperature change. If it is a stagnant room and no AC is on, it may change the room a lot if it is sealed up and small. You need to understand more thermodynamics to allow anyone to answer your question reasonably.

I have a 300W light bulb, I feel that after 6 hours when the AC is not on. Winter heating was never so cheap here in Texas.

Answer 3

Both the room and you will get warmer because more people together will release more body heat into the room. You can increase the temperature of an object by turning up the radiator, putting something like wool or cotton around the object [note: you said increase the temperature, that could be anything], holding the object in you hands and things like that. Hope I helped!

Answer 4

A 75 Watt bulb produces 256 BTU/Hr, which is enough heat to raise the temperature of 2 Lb. of water by 128 Deg. F.

Answer 5

Surely lights increase tempreature. But for sufficient increase you need to compare the size of the room with the bulb.

Answer 6

normal light bulbs can effect room tempurature.



when you have light it gives off heat so it always will effect it in some reguard so any where between .00001 to 4 or 5 should be reasonable

Answer 7

yes it increases the room temperature so if anyone has a habit of being awake late night, it is better to use low power consuming tube lights or lights with low watts and milky coating
