- Dark-sky lighting minimizes light pollution, directing light downward to reduce glare and sky glow.
- It enhances safety by reducing dangerous disability glare for drivers and pedestrians, contrary to the belief that brighter light equals safer environments.
- Exposure to darkness supports circadian rhythms, with blue light from white LEDs potentially harming health by disrupting sleep and contributing to diseases.
- Artificial lighting disrupts ecosystems, harming wildlife like birds, sea turtles, and insects; amber dark-sky lighting helps protect these species.
- Dark-sky lighting uses only necessary light, reducing energy waste—about 30% of outdoor lighting in the U.S. is wasted, costing billions annually.
- It preserves night skies by combating light pollution, allowing views of stars and celestial bodies, as demonstrated in communities like Flagstaff, AZ.
- Characteristics include fully shielded fixtures, amber color instead of blue/white, dimmed intensity, and use of timers or motion detectors.
- Community action is essential; advocating for amber dark-sky lighting with officials can prevent the spread of harmful white LED streetlights.
