What can you do

  • Use shielded lighting to ensure light is pointed downwards
  • The International Dark Sky Association recommends using LEDs with 3000 Kelvin or below
  • Find Dark Sky Friendly Lighting
  • High color temperature LEDs(5000 and above) have a lot of blue light in their spectrum. Blue light creates a lot of glare, impairs vision, brightens the sky more than any other color. People actually hate harsh blue lights
  • Light only what's needed, when needed and the amount that's needed
  • Few lights evenly lighting a space is better than one or two very bright lights
  • Use motion sensors/timers/adaptive lighting rather than leaving lights on all night
