Assuming you pay 10 cents per kw/hour from your power company then it would cost 7 tenths of a cent.
First convert watts to killowats (by dividing by 1000), so 70/1000=0.07kw
Now multiply how many kw (kilowatts) the device uses by the local rate (you need to call your power company or look at a recent bill), we will assume 10 cents for now.
So 0.07kw times 0.10 (kw/hour rate) comes to 0.007 to run this for one hour.
To carry it further, to run this light for a whole day (24 hours):
0.007 times 24 = 0.168 (16.8 cents per day).
If you leave the light on for 8 hours a day for a month:
0.007 times 8 (hours per day) times 30 (days in a month) = 1.68
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)

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
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.
about 2.00 dollars. it depends on the size and shape and the number of volts you get!

That would depend on the how many watts the light bulb you are talking about. Also, it would depend on how much your power company charges for electricity.
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.
i dont know ether if you get the answer can u send it to me plz

Typical home energy cost is 10 cents per kilowatt hour A 60 watt bulb running for one hour uses 60 watt hours .10 X (60/1000) = .006 cents per hour 16.66 60watt bulbs on for one hour would cost 10 cents.

the price of the bulb
about 2-3 dolers
That bulb is 100 watts or 0.1 kilowatts so it uses 0.1 kilowatt-hour of energy each hour, which costs about £0.015

The first commercially available light bulb cost $1 in 1881, which was three years after Thomas Edison developed the first practical incandescent light bulb. The Seattle Times reveals the $1 price in 1881 translates to $23 in 2013. By 1910, the cost of a light bulb dropped to 17 cents.
