According to tree hugger Dusseldorf Germany has decided to replace 10000 of their gas street lamps with LEDs. They bring up the excellent point LEDs are more directional which will save on light pollution as well as energy. I still don't understand lack of motion sensors though!
Especially with LEDs that are quick to turn on and off (unlike high pressure sodium vapor) and LEDs are dimmable (when no motion only use 1 in 10 LEDs)

We saw LED lighting everywhere in Europe... it seemed it was mostly used for lighting pathways like this tiny tunnel in rural Cinque Terre Italy
