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.

What is the main reason fore a light bulb to stop working?
the main reason for a light bulb to break is, the light bulb heats the tungstin wire. When the tungstin wire gets heated to much it breaks, causing thi light bulb to stop working.
How much was the light bulb in 1879?
Zero, nothing. It wasn't until 1880 that Edison patented the first commercially viable incandescent light bulb.
Why do you think a light bulb feels warm?
A light bulb is designed to take electrical energy and radiate it as electromagnetic energy.It would be nice of all of that energy came out in the form of light, but that has never been accomplished yet. An incandescent light bulb ... the original kind ... radiates much more heatenergy than light energy. In other words, an incandescent light bulb works much more efficientlyas a heater than it does as a source of light.
Could you live without the light bulb being invented?
yes because fire has always been use as light so definatly you can live without the invention of a light bulb and a light bulb was invented to make life much more easier
What happens when you put an electric motor with higher resistance and a light bulb with less resistance in a series circuit. does the bulb light up and motor spin. or only the motor spin?
(Another possibility is: Bulb lights up and motor does not spin.)The result all depends on the relative resistance of the bulb and the motor, becausethat determines how much of the supply voltage appears across the light bulb, andhow much across the motor.That's one of the big problems with a series circuit: The performance of one devicedepends on the characteristics of the other devices in the same circuit. If you turnthe light off, the motor can't run at all. If the load on the motor changes, then thelight bulb flickers. And if you change the light bulb and put in one with a differentresistance, then the strength of the motor changes.
What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
How hot does a 50 watt light bulb get?
This depends on the bulb design. A simple tungsten filament bulb might have a surface temperature of the bulb well above 100 C. A fluorescent lamp will be much cooler for the same light output.
How much does a person affect the temperature for an average size room?
About the same as a 100 watt incandescent light bulb.
How many veterinarians does it take to change a light bulb?
Three. One to change the bulb and two more to complain that an MD makes ten times as much for the same procedure!
How much does it cost to get the headlights changed in a 2003 Nissan altima?
typically, you only change the bulb (it the bulb light is out). they usually cost a few dollars, if it is a busted headlight, do not know.
Why does a bulb blow?
Because to much electricity is getting through to the light bulb.
What will happen if you put a light bulb in a microwave?
Actually if you microwave a small bulb that does not resist high temperature it explodes in about one minute or something. If not it will do awesome colors, but it will finish by blowing up, taking much time
How much electricity does electric bulb uses?
The quantity of power consumed by a light bulb is dependant on the wattage of the bulb.
How do you change rear light bulb on peugeot 306?
I have an estate, so the procedure might be slightly different on a hatchback, but not by much. The rear light cluster is attached via a screw behind the facia panel at the back. You will need to remove the plastic panel in the boot behind the light cluster and unscrew the unit before you can remove it to change the bulb.
What is the main reason fore a light bulb to stop working?
the main reason for a light bulb to break is, the light bulb heats the tungstin wire. When the tungstin wire gets heated to much it breaks, causing thi light bulb to stop working.
How did inventions such as the light bulb and the telegraph change daily life in the late 1800s?
the telegraph enabled information to travel much faster considering the time period. the light bulb allowed people to work longer hours. both made the pathway to more technological advances that helped change the economy.
How much time would a 60w light bulb to run out of light?
The average lifetime of an incandescent bulb is around 2000 hours.
