The number of poles necessary is determined by the area to be illuminated and the amount of brightness required across the property. If the parking lot has to be well lighted, more lights will be required than if the parking lot just requires a minimal degree of illumination for basic safety. You’ll need poles and lights if you’re starting from scratch and want to light up a full lot (which is the most typical situation we see with our clients). The number of light fixtures you will use on the pole and the additional lamp post cost and light fixtures are other factors to consider.
