Click calculate to find out the electricity cost of a single incandescent light bulb running at 60 Watts for 5 hours a day @ $0.10 per a kWh, keep in mind you can edit the numbers in the calculator. Cost Per Hour: Cost Per Day:ncandescent light bulbs have an average lifespan of 1000 hours or 41.6 days running 24/7. While comparable CFL light bulbs last an average of 9,000 hours or 375 days running 24/7 and an LED light bulb lasts 50,000 hours or 2,083 days.
If you are paying about 12p per Kwh, then a 60 watt lamp will cost about Â£0.007p or 7/10 of a penny per hour. If you swap it for an energy saving equivalent of 11/12 watts you will get 5 hours for the same price and the lamp will last for up to 18 times longer, depending on the brand. kilowatt hour is the same as a unit of electricty, which roughly costs 9 pence. This means you can run 1000w (1Kw) for 1 hour for 9pence. So if you divide 1000 by 16.66 you get 60 (the light bulb) then divide 9 pence by 16.66 you get 0.54pence.
