Generally, the height of street light poles ranges from 3 meters to 14 meters, depending on design requirements. For major roads in large cities, street light poles of 8 meters or higher are typically chosen, while residential roads may require poles of 6 meters or less. Depending on the wattage of LED street lights, installation heights generally range from 8 to 12 meters for 150W and 200W models, or 6 meters for 50W and 80W models. Most street lights are installed at a height of 15 to 20 feet above the road surface to balance vehicle passage and ground lighting requirements.
