FAQs
- Humans evolved to a cycle of day and night. Research suggests that artificial light at night can negatively affect health, increasing risks for obesity, depression, sleep disorders, and more.
- Many species are nocturnal and artificial light can affect their reproduction and predatory cycles.
- Birds that migrate or hunt at night navigate by moonlight and starlight. Artificial light can cause them to wander off course toward dangerous structures causing them to collide. Every year millions of birds die colliding with buildings.
- Approximately 30% of outdoor lighting is waste, shining when and where it is not needed. Not only is this economically inefficient, it increases emissions affecting the natural environment.
- Installing quality outdoor lighting could cut energy use by 60 - 70%.

What about safety and night time visibility?
A dark sky does not necessarily mean a dark ground. Smart lighting that directs light where it is needed creates a balance between safety and starlight.
Outdoor lighting is intended to enhance safety and security at night, but too much lighting can actually have the opposite effect. Visibility should always be the goal. Glare from bright, unshielded lights actually decreases safety because it shines into our eyes and constricts our pupils. This can not only be blinding, it also makes it more difficult for our eyes to adjust to low-light conditions.
