## How much electricity does 1 LED lights use?

Cost Comparison Between LEDs, CFLs, and Incandescent Light Bulbs

LED | Incandescent | |
---|---|---|

Cost per bulb | $5 | $1 |

KWh of electricity used over 25,000 hours | 212.5 | 1500 |

Cost of electricity (@ 0.10 per KWh) | $21.25 | $150 |

Bulbs needed for 25,000 hours of use | 1 | 21 |

## How much does it cost to run one LED light bulb for 24 hours?

Leaving the bulb on the whole day will therefore cost you: 0.06 (60 watts / 1000) kilowatts x 24 hours x 12 cents = **approximately 20 cents** in one day.

## How much power does a 5w LED bulb use?

5 watt led bulb power consumption per hour:

Yearly power consumption = 5*24*365 + 10% power loss = 43800 + 4380 = **48180 Watts hour**. Converting into units 48.18 units per year is the yearly consumption of 5 watts LED bulbs.

## How many watts does a fridge use?

The average home refrigerator uses **350-780 watts**. Refrigerator power usage depends on different factors, such as what kind of fridge you own, its size and age, the kitchen’s ambient temperature, the type of refrigerator, and where you place it.

## How do you calculate LED wattage?

To calculate an LED’s power use, simply **multiply the LED’s voltage (in volts) by the LED’s current (in amperes)**. The result, measured in watts, is the amount of power your LEDs use. For example, if your LED has a voltage of 3.6 and a current of 20 milliamperes, it will use 72 milliwatts of power.
