Yard Light Consumption Calculator.

Have you ever wondered how much power your yard light really uses? 

By using this simple formula, you can calculate the approximate consumption of your yard light.

Watts / 1000 x Hours x Days in Month = kWh

Example: 40 / 1000 x 12 x 31 = 14.88 kWh

In the above example, a 40-watt yard light that is on for 12 hours a day for 31 days, uses 14.88 kWh.

Older yard lights and different bulbs may not be as efficient on electricity. Please refer to your own devices to determine approximate consumption.
