Calgary has finished replacing 80,000 travel lights with LED bulbs some-more than a year forward of schedule.

The new LED fixtures focus light on a some-more slight area, a city said, concentrating enlightenment on streets and sidewalks and shortening light “spillage” upward, so shortening light pollution.
Astronaut Scott Kelly tweeted a print of a city from circuit  in Nov 2015 that showed a transition in progress.
