“Which night sky do you fall under?” (Photo: Courtesy of Stellarium)
“If you happen to inhabit a major metropolitan city—say Los Angeles—you might see a passing airplane or a spotlight for some distant movie premiere.
What you probably won’t see are any of the 400 billion stars populating the night sky.
A 2008 study commissioned by the U.S. Department of Energy estimated that, in 2007, stationary outdoor lighting consumed more than 178 billion kilowatt-hours of electricity annually.”
It’s true. ‘Excellent dark sky sites’ are quickly becoming increasingly rare around the world. As population increases, light pollution increases. Unless lighting principles are changed, the darkness of the night sky will continue to diminish. One small change to a light’s design can single-handedly eliminate light pollution: shielded fixtures. How? Shielded liht fixtures direct the light downward, where it is needed the most. Traditional lights possess no such design and thus, emit unnecessary amounts of light into the sky and require significantly more energy to power. Combining energy efficient light bulbs with shielded fixtures and motion-sensors, creates a perfect balance of decreased energy consumption, increased security and low maintenance. It’s a win-win-win situation.
Let there be night!
