I already knew that bright exterior lights are annoying to neighbors and that it would be nicer to see more stars at night, but I learned a few more reasons to avoid light pollution. So many nocturnal animals have their normal patterns disrupted by bright night time lights. Birds and insects in particular. I have a new love for curtains on windows to keep the interior lights from lighting up the outdoors. I had considered curtains mainly for privacy and keeping the sunshine out, but hadn’t worried about all the light that can spill out of a house when lights are on at night. Because LED lights use so little electricity the Earth’s light pollution problem is getting worse. It doesn’t cost very much to leave exterior lights on all night and this sometimes seems simpler than fancy lighting controls. Now I will be thinking of the nocturnal creatures as I plan my architectural lighting.
