Artificial light has been a hallmark of civilization. You’ve probably seen the night pictures of the globe where industrial cities sparkle.

We carry flashlights the way Oregonians carry umbrellas. In parts of Europe, the street lights only come on when people walk by. We can save energy, improve our health and protect nature by making the stars shine again.
