Go Lights Out 2020

Mark your calendars for the 5th annual Lights Out Portland, an event to kick off fall lights out where residential households and commercial buildings dim their lighting in order to raise awareness about the impact of light pollution on migrating birds, about wasted energy in the form of light thrown up into the sky, and about preserving our ability to see stars from the city.

Building owners, businesses, and residents are encouraged to keep joining us from dusk to dawn each night from September 19 through October 19–the period during which peak numbers of birds will be moving through our airspace.

Visit CSU’s Lights Out Alerts page for Red Alert nights when we really need to take action! We will also post Red Alert nights on our Facebook Page.

Light Pollution drowns out the stars that migrating birds are using to navigate and lures them into cities where they are at risk of colliding with windows. Across the US, nearly 1 billion birds die every year as a result of hitting a window. There are also serious human health concerns about exposure to artificial light at night, which disrupts our circadian rhythms.

Building owners, tenants in residential buildings, and residential households are encouraged to participate by turning off unnecessary lighting and then getting out somewhere to see the stars!

From dusk to dawn, building owners are asked to:

  • Turn off rooftop lighting and exterior architectural lighting
  • Turn off or dim lobby/atrium lighting
  • Turn off interior lights wherever possible
  • People in houses, apartments and condos are asked to:
  • Turn off any unnecessary outdoor lighting
  • Draw blinds or curtains in rooms where lights are in use
  • Get outside to see the night sky!
