Effective outdoor lighting creates the right aesthetic while supporting safety and commerce. Because excessive artificial light – known as light pollution – can have environmental consequences, dark sky-friendly lighting was developed to minimize the harmful effects of light pollution on humans, wildlife and our climate.

Key tenets of dark sky-friendly lighting include:

• Only light the area that needs it

• Be no brighter than necessary

• Minimize blue light emissions

• Be fully shielded (pointing downward) 



• Increases safety by reducing glare for drivers and pedestrians

• Improves appearance of night sky – greater contrast between sky and stars

• Positive economic impact to surrounding communities
