Fortunately, in Israel, we have no LED streetlights at all! The only exterior lighting applications in Israel that uses LEDs are: color washing and decoration of exterior structures. For example: Philips/Color Kineticks RGB LED floods are used to light small buildings and architectures and are changing their colors. Also colored LEDs used to decorate buildings and wide bridges with tunnels under them and to light the roads inside the tunnels with colored lighting.
In Haifa the municipality did a LED street lighting test at the edge of "Saar Haalia" neighborhood with two flat white LED streetlights. They were produced the same amount of light as a street light with a 125W /DX MV lamps. After several months the municipality removed them and returned the former two AEG Koffer 150 HPS fixtures with one 150W-250W HPS lamp each.

Unfotunately, we live in a throw away society where many people think new is better but it's really not and getting through to city council members is near impossible.

For SOME things...new IS better.....while other new things are not better....it depends on what you are talking about...in general.......

mercuryvaporrocks:
I meant streetlighting in general.

It is better to start using HG-free HPS lamps in street lights instead of using LEDs. These HPS lamps don't contain mercury, don't cycles at EOL, and also are much more efficient because they have 300 torr Xenon pressure instead of 80 torr of regular HPS, which result in 140 lm/w max. 10 lm/w less then the european 300 torr Xenon HPS lamps with mercury, but still much more efficient then a regular HPS lamps.
These HG-free HPS lamps have 2100K and 18% CRI compared to 2000K and 25% CRI of standard HPS lamps.
