The bulb takes a power measured in watts. Each hour it uses energy equal to that number of watts, as watt-hours.
A 60 W bulb uses 60 watt-hours in 1 hour, or 600 watt-hours in 10 hours.

∙ 14y agoDepends on your electric rate and lamp wattage, but for formula is this:
100 Watts X 24 hours / 1,000 KWH X elec rate .08 = .192 per day.
If you are trying to decide on weather to buy fluorescent vs regular consider this:
Example: 100 Watt lamp costs .50 and is rated for 1000 hours.
100 Watts X 1,000 Hours = 100,000 Watts / 1,000 = 100 KWH
100 Killowatt Hours X Electric rate .08 = 8.00 + .50 cost of lamp
Total cost to run that light bulb (on average rated life) is $8.50
That's why the new fluorescent lamps are so cost effective. Do the math.
18 Watts (100 equivelent) X 10,000 Hours = 180,000 W / 1,000 = 180KWH X .08 = 14.40 + 6.00 cost of lamp = $20.40 Total. Sounds higher but the lamp lasts 10 times longer. So 20.40 / 10 = $2.04 each
It's a little bit more upfront but easily pays for itself in the long run.

∙ 13y agoVery little but it depends on your particular cost for electricity and the rating on the light bulb. Typically LED bulbs use less than 10W of power. If your electric company changes say 10 cents per kilowatt hour, then it would cost 10cents*0.010kW = 0.1 cents.

∙ 15y agoFirst you have to know the price for 1 kWh. Suppose it was 12 cents. That is usually written .1200 per kWh. Or, 12 cents to use a 100 watt bulb for 10 hours. Because 10 x 100= 1,000 So, it would be 10% of 1 kWh. And also 10% of the cost per kWh which is 12 cents. So, 1 hours use is 1.2 cents in this example.

∙ 15y agoThat depends on
(a) the price you pay for a unit of electricity (which differs around the world, and even within countries)
(b) the wattage of the bulb used.

How much per hour does it cost to use a 150 watt light bulb?
The actual cost will depend on the charge by your supplier. It can be calculated by finding the cost of 15% of one unit of electricity (kw hour)
What watt fluorescent bulb can you use to replace a 60watt incandescent bulb?
fluorescents are about 5x as efficientso a 12W will give about as much light
How much money does it take for the electricity of an incandescent light bulb use?
You are charged by Kilowatt Hours. An average cost is about 12 cents. To make the math easy, assume a standard 100 watt incandescent bulb. If you had ten of them turned on for an hour it would cost 12 cents.
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 9 watt light bulb cost to run for 1 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

How much does a light bulb cost to run daily?
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.
