What is light pollution?
Light pollution is the introduction of artificial light into the night sky. Artificial lighting is the primary cause of sky glow, obscuring the stars and creating perpetual twilight. Light pollution contributes to light trespass issues on public and private properties. Today, 80% of the US population cannot see the Milky Way.
Low Pressure Sodium (LPS) fixtures were an excellent choice for cities that require Dark Sky compliant lighting as well as astronomical observatories and environmentally sensitive areas.
