Reading about Solux Lighting reminded me of something I've been meaning to Post....I'm wondering specifically how Institutions handle their outside lighting. As an Amateur Astronomer I'm very much aware of the problem of the misuse of lighting outdoors that causes the lighting up of birds and airplanes. Most people today can't see the Stars as all humanity was able to. This wouldn't be such a big deal except that Light isn't free of course it costs money. Each year we in the United States spend at least $ 1.5 Billion doing this. For a more complete discussion of this problem, I invite you to go to the International Dark-Sky Assoc.
