I know rates vary but approximately what does it cost you to run a 100 watt bulb 24/7 each month? Is it $2.00 a month? $5.00 a month? Thanks in advance!

It is 72 kilowatt hours. So if you are at a rough average of .12 for a rate, about $8.65

Watts x hours x days divided by 1,000 give you kilowatt hours in a set time.

Cost per kilowatt hour varies depending on where you live. And in many places it depends on how much you use. Our cost range from $0.076 for the first 500 hours to $0.0971 for everything over 1000 hours. :beer:
