'Sconset's Dark Sky
Those who visit 'Sconset for the first time are often in awe of our dark sky and the amazing, unobstructed view of the stars. Miraculously, it is like time has passed us by and we still have a natural resource that many communities can only dream about, a night sky free from light pollution. It is a treasure that many of us take for granted, but we shouldn't. Our view of the starry skies is at risk of slowly, imperceptibly, disappearing if we're not careful. Let's all work together to protect our dark sky from the glare of artificial lights so it will be preserved in all its beauty.
Contact us if you have any questions about, or suggestions for, our Dark Sky initiative.
Board Dark Sky Policy
Replace bad lights with good lights.
You'll save energy and money. You'll be a good neighbor. And you'll help preserve our view of the stars.
Which bulb should you use for your outdoor light fixtures?
The Civic Association recommends an LED bulb with no more than 180 lumens (level of brightness) and no more than 2700 kelvins (hue of the light emitted). A bulb with 180 lumens and 2700 kelvins will be a soft, warm white light that is roughly equivalent to a 25 watt incandescent light bulb. Available here

What You Can Do
We can all help protect 'Sconset's dark sky through our individual efforts. Here are some things you can do that will make a real difference:
NANTUCKET'S OUTDOOR LIGHTING ORDINANCE
A violation of Nantucket's outdoor lighting ordinance is subject to a penalty of $100 each day a violation continues after receiving a warning from the Lighting Enforcement Officer of Nantucket and being given 30 days to come into compliance.
Among other things, the following are prohibited for residential exterior lighting, with certain exceptions, if the lighting output is more than 600 lumens (about 40 watts incandescent and 10 watts LED). (See the ordinance itself for more detail, including additional restrictions, and contact the Lighting Enforcement Officer with any questions.)
Nantucket's Lighting Enforcement Officer:
Marcus Silverstein, 508-325-7587, Ext. 7021;
Before reporting a violation, please discuss it with your neighbor to see if he or she is willing to take corrective action without involving the Lighting Enforcement Officer!
Your Neighbor's Lighting
Does your neighbor have an unshielded fixture that casts a bright light onto your property and even inside your home? Here are some practical steps you can take.
Not as much light pollution as in other communities,
The Civic Association will contact the appropriate authorities to ask them to correct the situation.
The goal will be to have street lights that don't interfere with our beautiful dark sky but are still sufficiently bright to provide visibility at key intersections.
Regardless of the street lights, please always use FLASHLIGHTS and BIKE LIGHTS at night to ensure your personal safety!
