Flagstaff and ADOT set new global precedent for dark sky city lights
The city of Flagstaff and the Arizona Department of Transportation (ADOT) are replacing thousands of street light bulbs with amber LED lights to reduce light pollution, making Flagstaff the first city in the world to use amber LEDs on a city scale. The project aims to protect the area's dark skies, a characteristic that has earned Flagstaff the status of the first international dark sky city in the world.
The city of Flagstaff and the Arizona Department of Transportation (ADOT) are working together to reduce light pollution by replacing thousands of street light bulbs with new amber LED lights. This project will make Flagstaff the first city in the world to use amber LEDs to protect dark skies on a city scale. The city's efforts to reduce light pollution have been ongoing for decades, and it was designated as the first international dark sky city in the world. The Milky Way galaxy is not visible to more than 80 percent of North America due to light pollution, but Flagstaff's dark skies remain relatively unpolluted. ADOT is set to replace almost 400 light bulbs and fixtures on major roads around Flagstaff, including I-40 and I-17, after testing for safety. The installation of these new lights is expected to begin next month.
