Should I choose 120 V or 480 V for the street lights?

I want to prevent the influence of voltage drops, so I am considering using 480 V. Is it a good idea?

480 V is more dangerous than 120 V, so it may cause trouble for the maintenance operators. Also, if you use 480 V, you have to make sure the wire has a strong insulation ability, which may add to the costs. But for large areas like the parking lot, 480 V can effectively reduce the voltage drop. To balance the pros and cons, you can use a transformer.
