How much energy does a street light use?
Energy consumption of a street light depends on the wattage of the lamp and the location of the light, which determines the number of hours of operation each night. Typically, street lights on main roads contain a 150 watt lamp, while those on residential roads contain a 50 watt lamp. In simple terms, the electricity consumed by an ‘average’ street light will cost £16 per year, or just 4.5 pence per night.
