It depends on the bulb, how many watts it is.
All bulbs are marked with the correct voltage and the power taken, in watts. You multiply the watts by the number of hours to find the watt-hours of energy used. Then divide by 1000 to find the kilowatt-hours. A kilowatt-hour is also called a unit and you pay about £0.15 for a unit of electricity.
Let's say it's a 100 watt bulb running for 24 hours. That uses 2400 watt-hours or 2.4 kilowatt-hours, which costs about 2.4 x £0.15 which is £0.36.
a single incandescent light bulb is around $1.49
ahm...depends on the cost per watt charged by your local provider... how much is it?
You have to have three factors to calculate this cost. First what you are charged per Kw/hr from your power supplier, second the wattage size of the bulb that you want to do the calculation on and third the voltage of the bulb. Give me these and I can tell you how it costs to run the bulb per hour.
The average lifetime of an incandescent bulb is around 2000 hours.
$40.00 a year
In 100 hours it will use 6 kilowatt-hours (units) of electrical energywhich would cost around £1 or $1.
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.
About 7 cents an hour.
Unfortunately this answer is dependant completely on the "kilowatt per hour" your company charges you. If I receive this information from you then i will be more than happy to answer your question. -Tychusfindlay919

Yes, absolutely. As long as the LED bulb and incandescent bulb have the same base they will both fit the socket. The LED bulb will also run much cooler than the original incandescent bulb.
No
No, compact fluorescent bulbs run much cooler that an incandescent bulb. A CF bulb can be unscrewed when the lamp is on whereas an incandescent will give you a bad burn if this is tried.
