My city replaced it's old sodium lights with LEDs this year, and I was afraid they would do something similar but it's actually much better.
The LEDs they installed have a much narrower beam, around 45 degrees vs 180 for the sodium lamps. My apartment is at the level of street lamps, so the light would shine in directly through the window in the living room. Now I get only reflected light in.
The LED lights have around the same intensity as the sodium lamps, and because of the smaller beam angle, streets feel darker. However as the light is directed mainly on the road, it doesn't have any impact on driving.
The colour temperature is around 3500K which is still a bit colder than what I'd prefer. The colour temperature of sodium lamps definately invokes feelings of nostalgia. Part of this is because getting warmer than ~3000K LEDs is basically impossible as there is very little market demand, so nobody makes them.
