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.
The 23 Watt CFL bulb cost $4.60 ($92 / 20 = $4.60) annually compared to $20 ($400 / 20 = $20.00) for a 100 Watt Incandescent bulb.n this case we are going to calculate the cost of a 23 Watt CFL and compare that to what you are going to replace, the 100 Watt incandescent.
