What is Dark-Sky Lighting?

· It's simply a way of lighting that helps keep the sky dark by fully shielding the light bulb on the top and sides so the light is directed down rather than to the sides and up to the sky, which creates glare, excess light and hides our stars. (Skip to 4:50 of "Losing the Dark," below, to see this demonstrated). See photo examples.

· It is amber in color instead of blue, green or white. Amber LEDs are a better choice than warm white or low CCT white LEDS. However, choose warm white or low CCT (2700 kelvin or less) over a higher kelvin white LED. Find amber LED sources here. For further understanding, please see Dark-Sky Resources.

· It is dimmed and no brighter than necessary, is only used where or when needed, and often uses timers or motion detectors.

This solution to light pollution began with Flagstaff Dark Skies Coalition, when in the 1950s, they realized the necessity of protecting their dark skies, and they now have the darkest skies of probably any illuminated city you will find. They use mostly *amber* dark-sky lighting, and it's now widely available--people just need to know about it.

Lighting improves visibility and decreases concealment in public settings, thus contributing to increased safety.

skymaps01 — 2022-03-25 17:11:29 UTC

according to research quoted in the New York State Energy Research and Development Authority How-to Guide to Effective Energy-Efficient Street Lighting for Municipal Elected/Appointed Officials,1 simply increasing light levels beyond a certain point will neither make an area seem safer nor increase perceptions of safety. That is, glare and high light levels that make it harder for people to see can increase fear, whereas uniform lighting that eliminates both glare and dark shadows can lead to increased feelings of security.

Safety Concerns

A growing body of research demonstrates that digital billboards pose a threat to traffic safety. Digital billboards create dangerous and unavoidable driver distractions, by design and for the purpose of drawing driver attention away from the road and toward the advertisements. Images rotate every 6-10 seconds, and drivers will naturally look up at the sign to see what comes up next.

Light pollution is the human-caused alteration of outdoor light levels from those occurring naturally. It threatens ecological and commemorative integrity, interferes with amateur and research astronomy, degrades the appreciation of mythologies and cultural practices related to the night sky, mars wilderness experience and landscape beauty, carries risks to human health and wastes energy. Counterintuitively, excess outdoor lighting reduces safety and security.

Light pollution, or artificial light at night, is the excessive or poor use of artificial outdoor light, and it disrupts the natural patterns of wildlife, contributes to the increase in carbon dioxide (CO2) in the atmosphere, disrupts human sleep, and obscures the stars in the night sky.

The new world atlas of artificial night sky brightness

darkskyfriends — 2024-02-13 22:47:08 UTC

Artificial lights raise night sky luminance, creating the most visible effect of light pollution—artificial skyglow. Despite the increasing interest among scientists in fields such as ecology, astronomy, health care, and land-use planning, light pollution lacks a current quantification of its magnitude on a global scale. To overcome this, we present the world atlas of artificial sky luminance, computed with our light pollution propagation software using new high-resolution satellite data and new precision sky brightness measurements. This atlas shows that more than 80% of the world and more than 99% of the U.S. and European populations live under light-polluted skies. The Milky Way is hidden from more than one-third of humanity, including 60% of Europeans and nearly 80% of North Americans. Moreover, 23% of the world’s land surfaces between 75°N and 60°S, 88% of Europe, and almost half of the United States experience light-polluted nights.
