Light Pollution Basics

What is Light Pollution?

Simply stated, light pollution is light that shines where it is not needed or wanted.  It also includes lighting that is too bright.  It is easily recognized as:

• light that shines off the property where the light fixture is located

• light that shines onto your property from source not located on your property

• glaring light from poorly aimed fixtures or from a light that is too bright for its surroundings

• light that shines up into the sky.

Light pollution has several forms including glare, light trespass, over-lighting and uplighting.  Light pollution leads to energy waste and sky glow.
