We all agree that the old lighting systems were very bad, so why not give these new systems a chance, you might get to like the great reduction in sky glow which is what all the discussion is about on this and other forums.

No, in fact Cambridge's old fully-shielded HPS lighting was just fine except that HPS is indisputably ugly. The color temperature is fine, but the way it's emitted in a few narrow lines ends up looking terrible.
I haven't take enough sky readings to tell for sure, and the new lighting isn't fully in place. But I'm reasonably sure that it will end up increasing the skyglow.
In any case, there are other reasons to like or dislike streetlighting besides its effect on skyglow. The new, blue LEDs are ugly, harsh, and probably have bad health effects -- something that matters more than astronomy.
On the other hand there are people out there who are never happy, that just like to complain no matter what. As I said it is the way of the world today and that is one thing I am reasonably sure about ! I love the new LED lighting, for the reasons mentioned, and you know what all the deer and other smaller wildlife still cruise up and down our streets after dark, under the LED's and they don't look / act any different to me so maybe some of these detrimental health issues are all a pipe dream / wishful thinking against change ? Only time will tell and in the meantime why not enjoy any benefits ?

We just got our street LEDed today.

It's much dimmer in my front yard tonight. Not a lot of glare either. Overall, I think the lumen level is way down now..
The light is a lot weaker than the old Cobra-head lights. The light seems to be directed at the street and not my yard and house.
When I stand in the middle of my sidewalk, it's actually pretty dark now. Looking into the street.. It looks a lot dimmer.http://www.cloudynig...t-lights-today/

This iPhone4 pic is looking SE from my driveway. It looks a lot like what just saw. (<- is new LED)
There are other lights on the street that are brighter than these new LEDs..Since these lights are directed at the streets, snow will be a problem.. Until the snow plows come by..

Cheers,
Rich
