## How much does it cost to run an LED light bulb for 1 hour?

If you used a bulb for just two hours a day and paid the national average of 11.5 cents per kilowatt hour, a single 12-watt LED will cost you about \$1 per year. Comparable CFLs that consume about 14 watts come to \$1.17 per year and about \$5 a year for 60-watt incandescents in that scenario. (See formula.)

## How many volts does a 60 watt light bulb use?

Note – A light bulb rated at 60 watts at a voltage of 120 volts has a different filament resistance to consume 60 watts instead of 100. The filament in a 60 watt bulb has a resistance of 240 ohms as compared to 145 ohms for a 100 watt bulb. The above assumes that the voltage source is constant at 120 volts.

## Do light bulbs use a lot of electricity?
