Sodium (chem symbol = Na) Mercury vapor is also used in street lights. Low pressure sodium vapor street lights are amber/yellow in color, high pressure sodium lights are white and mercury vapor lights glow blueish white.
In my experience (northeast USA) most HIGH PRESSURE SODIUM street lights are 150 watt or 250 watt For example in NYC 250 watts is used at intersections and 150 watt everywhere else
1882 Thomas Edison opened th Pearl Street Power Station in New York City. The Pearl Street Station was one of the world's first central electric power plants and could power 5,000 lights. The Pearl Street Station was a direct current (DC) power system, unlike the power systems that we use today which use alternating current (AC). By the 1950's, electricity was finally reaching the majority of rural homes.

Municipal street lights get electricity from the regular power grid. Streetlights are often installed, operated and maintained by the electric utility company, under contract from the city. The electricity for a typical streetlight circuit is not metered; the utility simply charges the city based on the number of lights, since they know how much power each light consumes.
