What is Light Pollution?

Components of light pollution include:

  • Glare – excessive brightness that causes visual discomfort
  • Up-light – 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

Most of us are familiar with air, water, and land pollution. Did you know light can also be a pollutant?

The fact is that much outdoor lighting used at night is inefficient, overly bright, poorly targeted, improperly shielded. This light, and the electricity used to create it, is being wasted by spilling it into the night sky, rather than focusing it on to the actual objects and areas that require illumination.

How Bad is Light Pollution?

If you live in an urban or suburban area all you have to do to see this type of pollution is go outside at night and look up at the sky. Below is a pic Before (with street lighting) and After (blackout, massive power outage).

Effects of Light Pollution

Fortunately, concern about light pollution is rising dramatically. For example, the Title 24 outdoor lighting guidance, set by the California Energy Commission states that: All outdoor replacement Street Lights that are greater than 150W must meet the Up-light and Glare lumen limits as below. "U" refers to Up-light/Sky-glow, must be zero.
