  1. Protecting Our Night Sky LIGHTS OUT BEND

  2. Dark Sky Community

  3. Why Become a DSC • Benefits to Human Health • Benefits to Wildlife • Save Money • Ecotourism • Safety • Preserve our Night Sky

  4. What is “Light Pollution”? • Answer: The inappropriate or excessive use of artificial light causing: • - Glare • Light trespass • Sky glow • Decreased visibility at night • - Energy waste

  5. Overlighting Light Trespass Light Clutter Glare

  6. Light Pollution is Getting Worse

  7. How Does Light Pollution Affect Us? • Human Health • Higher electric bills with increased energy consumption • Disrupts the ecosystem and wildlife • False sense of security and safety

  8. A Nighttime Environment Doesn’t Require Brighter Lights - It Requires Smarter Lights

  9. A Smartly Lit Area

  10. How We Achieve Smart Lighting See What’s Lit, Not The Light! • FULLY shield the bulbs • Shine the lights DOWN • Light ONLY Where AND When • necessary

  11. Lighting examples: Gas Station Recessed lighting done poorly... ... and done well

  12. Residential Unshielded Light Shielded Light

  13. Commercial Unshielded Light Shielded Light

  14. The Color of a Light is Determined by it’s Correlated Color Temperature (CCT), measured in Kelvin (K) A lot of blue light 2000K 3000k And then… 4000K Very little blue light Almost NO blue light Mostly blue light 5000K Both the American Medical Asso. (AMA) and International Dark-Sky Asso. (IDA) recommend ALL lights be LESS THAN 3000K

  15. The American Medical Association recommends that outdoor lighting be 3000K or less for health reasons, such as sleep disruption (leads to obesity, depression, diabetes, and more) and disability glare. (Unanimously approved in June 2016 by representatives of entire AMA membership)

  16. Local Observatories: Pine Mountain and Sunriver

  17. The HOPservatory at Worthy Brewery

  18. “Of all the pollution we face, light pollution is perhaps the most easily remedied.” – Yerlyn Klinkenborg “Our Vanishing Night” National Geographic, November, 2008

  19. Can we do this? YES 2006 2008 Light Pollution Abatement at La Patrie,Quebec

  20. Lighting Solutions • Lights be Fully Shielded • Point Lights Downward • Only Light The Area Needed • Only Be On When Needed • Be No Brighter Than Necessary • Have a CCT of <3000K…the oranger the better

  21. What Can YOU do Now??? • Inspect the lighting around your Home and Business • Use light fixtures that fully shield the bulb and are pointing down • Talk to your friends, family and neighbors as a dark sky advocate • Spread the word online • Partake in the Citizens Science program at: www.globeatnight.com

  22. Bends Current Lighting OrdinanceFebruary 18, 2004 3.5.200 Outdoor Lighting Standards (C.1) All outdoor lighting fixtures subject to the section shall be designed as a full cut-off fixture or have a shielding method to direct light emissions down onto the site and not shine direct illumination or glare onto adjacent properties (C.2) All lighting for roadways, roadway signs, intersections, and pedestrian ways shall be designed or have opaque shielding method to direct light emissions downward and below the horizontal plane of the fixture in the permanently installed position

  23. Update Bends current lighting ordinance the include to following: • Fully-shielded or full cutoff standard for all fixtures over 1500 lumen initial lamp output • Establish a threshold of 3000 Kelvins for the allowable correlated color temperature of all fixtures • Restrictions on total amount of unshielded lighting • A policy at address over-lighting, such as energy density caps, lumens/acre caps • A provision that clearly indicates where, when and under what circumstances new public outdoor lighting is warranted and will be permitted • A provision that clearly requires that adaptive controls and curfews be employed in all future public lighting
