Did you know 80% of Americans can no longer see the Milky Way? Why? The cause is light pollution.Light that goes up is a waste of resources. The Dark Sky Association reports approximately 30% of outdoor lighting in the U.S. is wasted each year and mostly from lights that are not shielded. It adds up to $3 billion of wasted energy. Design to reduce pollution We can control out light pollution and it begins up front with design. Residential and business property owners and managers can make a difference by following simple guidelines:
- Reduce glare - excessive brightness.
- Avoid light trespass - light falling where it is not needed.
- Don't create light clutter by using bright, confusing and excessive groupings of lights.
- Choose full cut-off, shielded fixtures that direct light downward.
- Select proper brightness based on lumens and not wattage; 100-200 lumens is adequate.
- Work with a professional who knows CCT and select less than 3000K, preferably 2700K.
