For common street lights on the main streets of the city, the gap is between 25 and 50 meters. As for the street lights that work to light up gardens and landscapes, the gap can be around 20 meters. The gap between street light poles depends on the power of the light, the height of the pole, and the width and types of roads. If there is a 60-watt LED light and the height is 6 meters, the gap can be 15-18 meters.
