None, unless there's a radio or someting else built into the lamp base.

How much electricity costs when a light bulb is on for a long period of time?
It depends on variables. The amount your supplier charges per kilowatt. The wattage of the lamp. and how long it is left on.
Why does a bulb blow?
Because to much electricity is getting through to the light bulb.
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 much power does it take to light a lamp post?
Find out what the wattage of the bulb in the fixture is and you will have your answer.
How much electricity does a carrott produce?
It can hardly light a led bulb .
How much would it cost to run a 15 watt bulb non-stop for one year?
It depends how much you pay for electricity. A 15 Watt bulb would consume around 134 kWh of electricity. In the UK, electricity is around 10p a kWh, so it would cost £13.40 to run the bulb.
Why lamp gives light?
Because it is made to do so. An incandescent light bulb glows because electricity heats the filament until it is very hot and excites the atoms so much they emit "black body" radiation, much of which is in the visible part of the spectrum.
How much energy does a 60 watt light bulb use to yield light?
It depends on the type of bulb used. The term "60 watt" is the power consumed by an incandescent bulb producing about 800 lumens of light. This would use about 1.44 Kw-hr of electricity if operated continuously for 24 hours.A compact fluorescent lamp (CFL) would require only 13 to 15 watts, about 25% as much electricity.A light-emitting diode lamp (LED) would require only 6 to 8 watts, about 13% as much as the 60-watt.
How much electricity does a lamp used when turned off?
When the switch is open there should be no current flow.
What would happen to the filament in an IR lamp if too much current flowed into it?
The answer is no. However, it will run out of electricity if you put a lot of energy into the light bulb when you switch it on. Thank you for asking young fellow person who is unknown to me. -Your fellow friend
How much energy does it take to light fluorescent a light bulb for 1 hour?
The average home fluorescent lamp consumes 40W of power. Running for one hour it will consume 0.04 KWh. Units of electricity are charged per Kilowatt hour.
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.
