Dark sky compatible you ask? Animal friendly??
When we joined the International Dark Sky Association 10 years ago it was an impossible vision, we were looked on as radical wackos. But if you have ever slept under the stars, where the stars appear like so much glitter cast from horizon to horizon across the sky, then you know the beauty of a dark sky. I would rather have subtle functional lighting than something akin to the grand opening of an auto mall. Let’s work together to end light pollution.
