## How much electricity does an LED street light use per year?

Consumption for 12 hours is (12 hours*100 watt) = 1200 watt-hours = 1.2 kWh. So daily Electricity cost is (1.2 kWh*\$0.10) = \$0.12. Monthly Electricity street light cost is (\$0.12*30) = \$3.6. Or \$43.8 per year or \$438 in 10 years.

## How do you calculate power consumption of a street light?

Required Streetlight Watt = (Lux per Sq. Meter X Surface Area of Street Light) / Lumen per Watt.

1. Required Streetlight Watt = (Lux per Sq. Meter X Surface Area of Street Light) / Lumen per Watt.
2. Required Streetlight Watt = (6 X 1) / 20.
3. Required Streetlight Watt = 0.3 watt per Square Meter.
