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.

I've heard the LEDs offer much less light pollution, but perhaps that is not unique to technology difference and just the difference in lumens?

Also, I'm surprised there aren't equal lumen led lights.
