So 5 communities in the CoC (Altadore, Douglasdale, Marlborough, Brentwood, and Tuxedo Park) are either in the process of having their current high pressure sodium fixtures converted to LED fixtures (or have been completed) - Tuxedo Park has been completed and the difference when driving from Mount Pleasant into Tuxedo Park (or vice versa) is quite amazing. I am still quite unsure whether or not I totally like the new LED fixtures, certainly there are more dark areas/gaps on a converted block but that is offset by a much whiter light.
Overall, I can support a city wide conversion just on the basis of the daily energy savings the city would realize and the newer, whiter lighting would like be going back to the days of the mercury vapour fixtures in the 70's and earlier - almost retro in a way.
