An average

**CFL bulb**which provides 800 lumens will**use**only 13 to 15 watts compared to a similar incandescent**bulb**which**uses**60 watts. Click calculate to find out the**electricity**cost of a single**CFL light bulb**running at 14 Watts for 5 hours a day @ $0.10 per kWh, you can also modify the calculator.

Consequently, how much does it cost to run a light bulb for 24 hours?

So the **cost** of replacing per **24 hours** will be 24x 2/ 1000 or 4800/1000 cents or 4.8 cents. so the total **cost** in cents is . **24**+0.01+ 0.048 = 0.0298 or 29.8 cents. As you see **cost** calculations depend upon the situation.

Appliance | Typical Consumption Per Hour | Cost Per Hour (at 10 cents per kilowatt-hour) |
---|---|---|

Electric range burner | 1,000 watts | 10 cents |

Refrigerator | 1,000 watts | 10 cents |

Desktop computer and monitor | 400 watts | 4 cents |

Incandescent light bulb | 60 watts | 0.6 cents |

Likewise, are CFL bulbs energy efficient?

**CFLs** are four times more **efficient** and last up to 10 times longer than incandescents. A 22 watt **CFL** has about the same light output as a 100 watt **incandescent**. **CFLs** use 50 – 80% less **energy** than incandescents.

at 10 cents per KWH, it will cost $22 to run that sucker 24/7 for a year. About 6 cents a day. You can double those numerbs if your **electricity** is 20 cents per KWH. Remember this is for real watts, not equivalent watts of light.
