Outdoor Lighting Guide: Lighting with Nantucket in Mind

Check out this Guide for lots of practical guidance for complying with Nantucket's outdoor lighting bylaw (as amended at Nantucket's 2023 Annual Town Meeting) as well as for going beyond the minimum requirements of the bylaw to be as dark-sky and neighbor friendly as possible.


OUTDOOR LIGHTING GUIDE

Our Goals

Preserve Our Starry Nights

Protect Public Health and Safety

Protect Public Health and Safety

Did you know that most people in the world can't see the Milky Way where they live like those on Nantucket can?    


The naturally dark, star-studded sky is a priceless gift of Nature.  The National Park Service considers dark skies a natural resource, like clean air and clean water, that must be preserved for everyone.  Yet today, because of light pollution, most American children have never even seen the Milky Way.


If we control light pollution on Nantucket, we can preserve the wonder and beauty of the stars for those who live and visit there to enjoy -- and for the Maria Mitchell Association to continue its important work.

Protect Public Health and Safety

Excessive light at night -- especially blue-rich white light -- is bad for your health: 


  • It suppresses production of melatonin, leading to disrupted sleep cycles and elevated rates of serious diseases from diabetes to cancer. 
  • Glare from poorly shielded lights shines sideways into private yards and houses, and can temporarily blind road users.
  • Glare makes visibility worse, not better, and can even provide dark shadows for intruders to hide. 


Light should be only directed down, 

not out or up.

Protect Wildlife

Protect Wildlife

All animals -- including humans -- need darkness at night to thrive.  80% of mammals are nocturnal, and light pollution disrupts their feeding, mating, and migration.  Millions of birds, who navigate by the stars, become disoriented by bright lights and fly off course.  Entire species of fireflies are threatened with extinction because of light pollution, and pollinating insects -- which our food supply depends on -- are especially hurt by artificial light at night.
