The height of the parking lot poles can be 12-20 feet. The specific height depends on how large the parking lot is. Higher parking lot poles can light up larger areas. As the parking lot is also a place where many accidents happen, the requirements for the lighting system are relatively high. Not only should the brightness be high, the light should also be uniform. So the parking lot needs high poles. If the light poles are short, then you will need more of them than the high light poles to meet the requirements.
