Dark Sky Illumination Trend Addresses Adverse Effects of Light Pollution

Light pollution disturbs nature and can cost billions. Communities and cities are increasingly aware of the negative effects of light pollution and are passing ordinances to curb the problem. This affects how homeowners light their yards, and real estate professionals who know the ins and outs are better equipped to help their clients.

Have you looked at a nighttime photo map of the U.S. showing major cities with clusters of lights?  According to the article at the link, "Over the last 25 years, light pollution has increased by at least half and is growing about 10% annually, according to the International Dark-Sky Association (IDA), a Tucson, Ariz.-based organization focused on reversing the issue."  

Christmas lights, LED landscaping lights, expanding population in cities needing nighttime lighting, commercial displays, are all sources of increased light pollution.  It doesn't just block out our view of the nighttime sky, it impacts "plants, animals, insects, fish and people by affecting their natural rhythms and habits."   Further, " 'About 20 to 50% of the light that shines into the night sky is said to be lost due to fixtures being unshaded, which results in an estimated economic cost of about $3 billion, says Brian Liebel, Director of Strategic Initiatives at IDA. “We all pay that cost, either directly through utility bills or in the prices of goods and services, into which infrastructure costs are rolled.' ”

Tips by the IDA that property owners may want to consider are:

  • All light should have a definite purpose. Before installing any, homeowners should weigh reflective paint or self-luminous markers instead of permanently installing outdoor lighting.
  • Light should be directed only where needed, which is made easier with a shield and by aiming the light beam, so it points downward.
  • Low light levels limit the amount of light.
  • Light should be used only when it is needed rather than left on 24/7; that is why motion detectors and timers are useful.
  • Light colors should be carefully selected and preferably warmer colored rather than blue-violet. “The blue scatters the light more in the night sky and increases the level of light pollution,” Libel says.
