Around me there are a couple of methods of controlling street lighting.
Outside my house on the edge of the pavement there is a mini pillar (3 phase & neutral box with a 400/230v supply) for the houses in the street.
The street lighting is supplied from this (unmetered) and the control is through a photo electric cell switched from a few streets away. The supply is daisy chained and brings on a contactor in the box.
Newer house estates have a box with an enclosure and a lamp with a photo electric sensor in the head of a nearby lamp postcontrolling a contactor ant the street lights in the area. Each cabinet is independent of any others and they are not metered - just pickinhg up a supply from the street.
