Yes it will to some extent. as a mater of fact some bathroom lights are especial made to produce a lot of heat.

How much does a light bulb change the temperature of a room?
Very little, but it is noticeable, with a bright light in a small room. A light bulb puts out between 9 watts (energy-saving fluorescent light bulb) to approximately 100 watts (bright incandescent light bulb). Your average bar-heater, for comparison, puts out about between 1200-2400 watts.
How can you use up a source of energy when energy cannot be destroyed?
We run out of means to convert it. Coal is stored potential energy, if we use it all and the resulting heat energy escapes into space, we've lost that energy. World's water evaporates, no hydro power.
How much useful energy is in the output of a light bulb?
An ordinary incandescent light bulb puts out a good bit of light as well as a lot of heat - both useful forms of energy. Except that one uses a light bulb for the light. The heat is secondary and most often not desired. It can cause the room where used to be too warm and require more air conditioning to be cooled to be comfortable. Incandescent light bulbs can be rated as low as several milliwatts at low voltages to provide a small amount of light - as one would find on a radio dial from 50 to almost 100 years ago. They can also be several hundred watts, as would be use to light up a stadium. The energy out put in light of newer lights, such as compact florescent lights and LEDs are much better than incandescent bulbs and their heat output is much less - they're more efficient.
When we switch on the light electrical energy is converted into light energy. But when we switch off the light the produced light disappears. In which energy the produced light energy is converted to?
The produced disappears whether you switch it off or not - otherwise it would get brighter and brighter. In a closed room, the light would eventually be absorbed, and converted to heat. Outdoors, the light may go into outer space, going on and on and on... at a very high speed known as the "speed of light". In general, bet on heat. Light turns into heat.
What form of energy that is not useful is being released from the flashlight when it is on?
Incandescent light bulbs, including those used in traditional flashlights, generate heat by running an electric current through a wire filament. This heats the filament to incandescence, which generates light. But it also generates a lot of heat; up to about 80% of the energy is released as heat rather than light. Sometimes the heat is a useful side effect; for example, in a terrarium or over a buffet heat lamp, or in a cold room in the winter. But generally the heat is wasted energy. More modern flashlights, and many modern light fixtures, use Light-Emitting Diodes, or LEDs. These release about 60% of their energy as light. There's still some waste heat, but a much higher proportion of the energy consumption is light rather than heat. An intermediate development called "Compact Fluorescent Lights", or CFLs, were a major disappointment; they saved some energy but were hideously expensive, short-lived, and contained hazardous chemicals if they were broken.
Does a low-energy light-bulb create more heat in a room?
Compared to other types of light-bulb, energy-saving light bulbs will create less heat. This is because any wasted energy is converted to heat.
Can a light bulb heat up a room?
If a room is extremely well insulated and the wattage of the bulb is greater that the wattage heat loss then, yes a light bulb can heat up a room. The time that it takes to heat up a room would be considerable.
How do you find the amount of heat on a light bulb?
by going in a dark room and see if it have lot of heat to light up the room
What color should a room be painted to save energy?
Try light color that let in light so that your bulb wont have to produce as much energy to light up a room.
Why does light heat up a room?
it depends what type of bulb it is for example if it is an energy efficient bulb it uses about 80% of the electrical current into light and 20% heat but if it is a filiment bulb it uses only 30% of the electricity into light the other 70% is turned into heat so they are better heaters than light sources filliment bulbs can be found in old reading lamps on electric radiators filliment bulbs are being reduced because they aren't energy efficient hope you like the awnser :)
What kind of energy is used when turn on a light bulb is called?
Electricity is the type of energy that is used when you turn on a light bulb. When you leave a room, you use more energy by leaving the light on than if you turn it off and back on when you return.
When electrical energy is forcing its way through a light bulb is the energy used up?
From the point of view of the electric company, the energy is used up. It doesn't return to the power station, and they love it, because they get to send you a bill for it. In reality, energy is never created or destroyed. It always goes somewhere. In the case of the lightbulb, the energy comes from the power station, becomes transformed into heat and light energy in the lightbulb, and pours out of the glass envelope of the bulb. In the form of heat and light, the energy is absorbed or tossed around by the objects in the room.
How long would it take a light bulb to heat a room?
2000,00000,0000000 seconds or..... 15 hours
Why use a heater to warm up a room instead of a light bulb?
Light bulbs use a ton of energy. People have been lately switching to the fluorescent light bulbs which use less energy and last longer and don't give off nearly as much heat.
How much energy is wasted if the light bulb is 5 percent efficient?
It is not quite as straight forward as saying 95%. All energy going through the light bulb is being used in one form or another. If the room needs heat, the bulb is assisting in this heating. We use light bulbs like this for incubators or to keep pump rooms from freezing in the winter (two examples). In both of those cases, the light is really the only wasted portion of the energy consumed. If we are discussing only the light portion of the bulb. 95% of the energy goes to non visible light consumption.

What type of light is a 20 watt energy saving bulb Halogen Incandescent neon or fluorescent?
A 20 watt incandesent bulb is dim. For a medium sized room you need 100 watts. A 20 watt halogen bulb is brighter but still quite dim. These are marketed as low-energy but they are not. For a medium sized room you need 80 watts. A 20 watt fluorescent bulb can light a medium sized room quite brightly. This is a genuine low energy bulb.
