Darkness Appropriate at Night


Good Article in the non-printed Christian Science Monitor a few days ago:

...the National Park Service estimates that two-thirds of Americans cannot see the Milky Way from their homes.

...The cause of this stellar pall? Carelessly designed streetlamp fixtures, signs, and office lighting controls that pointlessly illuminate the sky, blocking our view of the universe.

...It would be one thing if all this light contributed to public safety, that is, if the illumination actually reduced the chances of a nighttime collision or mugging. But many of our light fixtures cast light sideways and upwards, temporarily blinding us and creating dark spots that we could otherwise see into. ... our light fixtures tend to create “glare bombs” that obscure as much as they illuminate.
