Light Nuisances - Ambient Light, Light Pollution, Glare



This page provides links to information resources on light nuisances including ambient light, light pollution and glare.  Light pollution includes misdirected light, stray light, avoidable reflected light, light during hours when it is not needed, and light levels in excess of what is necessary for the task. According to the Illuminating Engineering Society of America, light trespass complaints can usually be classified into two categories: unwanted light illuminating an area or property and excessive brightness in the normal field of vision. Problems of glare from building reflections are generally regulated through building and zoning codes. For new development, the SEPA Checklist (WAC 197-11-960) at Environmental Element (11) covers light and glare and includes questions.
