    Dare I say I think it might have been more practical for the petition to suggest streetlights are turned off around midnight, give us at least a few hours to admire the universe.

    lets hope the sensors are taken up, it doesn't say if the LED type throw any light up? It says its directional but how directional?

    hopefully the enviromental/cost issues will cause some serious reduction in light pollution so astronomers and non can get to enjoy the night skys

    Generally LED's throw light in one direction within a cone of 15degrees or so, however they are fitted with a light diffuser which will then spread it over a wider angle, so it depends on the spec. I have not come across these yet, but they'll certainly be of interest to me when I do. There will still be a large amount of light pollution from the cities as cars will be parked under the lights and - yes you've guessed it, reflect the light straight back up...
