What is Light Pollution?

The inappropriate or excessive use of artificial light – known as light pollution – can have serious environmental consequences for humans, wildlife, and our climate. Components of light pollution include:
  • Glare – excessive brightness that causes visual discomfort
  • Skyglow – brightening of the night sky over inhabited areas
  • Light trespass – light falling where it is not intended or needed
  • Clutter – bright, confusing and excessive groupings of light sources

Local Outdoor Lighting Ordinances

Many cities and counties have an outdoor lighting ordinance restricting lighting levels, duration, and color temperature. Check with your jurisdiction about regulations before investing in your outdoor landscape lighting system. See Dark Sky & Ordinances page.

What is a Dark Sky Light Fixture? 
The goal is to avoid sending light into the sky; therefore, we call it 'dark sky.' The specifics vary according to jurisdiction.  There are some basics qualities of dark sky lighting that seem universal. All light should be below the fixture, the light should be aimed down. International Dark Sky Organization has a listing of Dark Sky Certified fixtures. www.darksky.org  Find your nearest chapter and learn more.
