For sure, but if an entire city switches over to LED, that is a lot of electricity saved. Imagine the impact an entire country would have.

No. High pressure sodium lights produce more light for the same wattage. HPS produces 80-140 lumens per watt, LED produces 30-90 (https://ledlightinginfo.com/why-are-street-lights-yellow-and-not-white). They also tend to run slightly warmer which means they are less likely to be covered by snow. That’s why Europe is still using them everywhere.
