Outdoor Lighting Science Project Goal: To upgrade neighborhood lights so that all light shines below horizontal angles and not up into the night sky! Educational Materials: "Good Neighbor Outdoor Lighting" by Sky & Telescope Magazine IDA Information Sheet #25: "How to Talk to Your Neighbor Who Has a Bad Light" IDA Information Sheet #4: "Operating Data and Economics for Outdoor Lighting" - demonstrates how efficient, Dark-Sky Friendly outdoor lighting can generate big savings! IDA "Protecting Our Night Skies" Video: Excellent 10 minute in-depth report, narrated by "20/20's" Jay Schadler! Hardware: Relevant dark-sky friendly fixtures at http://www.darksky.org/fixtures/res.html and http://www.darksky.org/fixtures/fixtures.html. -Top Yardlight replacement: Heath-Zenith SL-5597 Full-Cutoff Motion-Sensor Floodlight Cost: $30.00 Available: Home Depot. -Top Lantern replacement: The "Glarebuster" Cost: $60.00 Available: Outdoor Lighting Associates or an ACE Hardware store near you. Various shield designs at http://members.aol.com/ctstarwchr/shielding.htm -Top Yardlight Converters: Hubbell "SkyCap", G.E. "SkyGard" Cost: $30.00 Available: Outdoor Lighting Associates. Demonstration: Develop a mobile lighting experiment composed of two "heat lamps" with large screw on/off shields, fitted with identical 13 watt compact fluorescents(that do not extend past shield). You will demonstrate the contrast between "shielded lighting" and unshielded lighting. The unshielded lighting, that is with the shield removed, replicates: "Acorns"-bulb up, Yardlights/Streetlights-bulb down. The shielded unit pointed downwards demonstrates the advantages of full-cutoff lighting. Let your audience see the difference for themselves! Involve neighbors in your project by emphasizing that low-glare, shielded lighting improves safety, visibility and efficiency. Adding a motion sensor significantly improves security and energy savings. In short, Everyone Wins! Document: Take "before" and "after" pictures illustrating your outdoor lighting makeover. If you can obtain a light meter, take "before" and "after" readings from various points in the yard. Sequel: Give demonstrations and presentations at city council and zoning meetings. Work with legislators on all government levels to preserve our greatest national heritage: the starry heavens! Be the driving force behind the United States' first national lighting ordinance! With the spirit of patience and perseverence, you'll make a difference in the battle against Light Pollution! "The world is changed one light at a time!" |
