Resources
- Street lighting technology is evolving rapidly and is tracked by the U.S. DOE's Municipal Solid-State Street Lighting Consortium which offers a variety of resources, such as performance calculators and model specifications, to guide municipalities and others in their evaluation and choice of LED street lighting products, which importantly includes the choice of color temperature (3000 or fewer degrees Kelvin generally preferred for Dark Skies) and color rendition. See MN Dept. of Transportation LED specifications.
- The comprehensive listing of LED streetlight resources by CERTs covers paybacks, bulb longevity, light trespass, maintenance cost savings, total cost-savings calculators, research in Minnesota, 'how-to' manuals, specifications and more. Also see the CERTs page on LED traffic signals.
- Use the International Dark-Sky Association Bad Streetlights guide to promote reduced/smarter outdoor lighting. See the GreenStep Dark Skies best practices for more.
- 6-minute video on research and a test of LED street lights with a focus group from three different vendors, run by Dakota Electric Association and the City of Apple Valley.
