Low pressure sodium lights were more efficient, but they emit a single wavelength of orange light. These lights were strongly disliked by people who liked to admire their car in the streetlights (I suppose).

… they used CFLs? The spiral fluorescents were invented in the 1980’s, I guess. I speculate the residential street lights used mercury vapor bulbs, which had a longer expected lifespan than fluorescents.

You need a good blackout curtain to deal with light pollution through your window.
