How Much Power Does a Night Light Use

Incandescent night lights use about 1 to 5 watts of power. The amount of power used by a night light is listed by the wattage the light uses. In addition, some night lights automatically shut off when room light increases during the day.

How much does it cost to run a night light for 24 hours?

Let’s say you have a 60-watt incandescent lightbulb and you are paying 12 cents per kWh of energy. 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 dusk to dawn light use?
