Home Lighting

How many exterior lights do you have around your home or property? Are you sure? Have you carefully considered each fixture’s need, function, or design? Are you minimizing light pollution in your own backyard? If not, you’re not alone. Unfortunately, much of our outdoor residential lighting is inefficient, poorly installed, or altogether unnecessary. 

These misguided lighting practices contribute to light pollution, disruption of wildlife, impact human health, and waste money and energy. As of 2018, the average American wastes 41-103 pounds of CO2 per year on excessive residential outdoor lighting alone (1). Across the country, this amounts to at least $1.4 to $3.5 billion wasted each year, unnecessarily lighting the dark around our homes. Our analysis also indicates that these numbers may grow as Americans are likely consuming more exterior lighting than ever before (2). 

Here’s the bright side: Light pollution is completely reversible.

DARK SKIES START AT HOME

Follow this step-by-step guide to conducting an outdoor lighting assessment around your house, apartment building, property line, community centre, or wherever to evaluate the impact of your light on the night. After completing the steps to make your home dark sky friendly, you can download and display a Dark Sky Friendly Home Certificate!

WHAT ABOUT…

…MY NEIGHBOR’S LIGHTING?

So you’ve addressed all your problem lighting, but what about the lighting that is beyond your control? Maybe your neighbour’s lighting is shining in your bedroom window, or your landlord or property manager needs to make changes. Check out these tips for working with your neighbour’s lighting. 

…MY SAFETY?

It’s important that your property is safe and responsibly lit to protect you from potential hazards, support wayfinding, or deter potential crime. But brighter does not equal safer. In fact, too much lighting can have the opposite effect. Learn more about lighting, crime, and safety. 

…MY STREETLIGHTS?

Estimates suggest that on average street lighting accounts for about 50% of a city’s total light emissions (4). Learn what you can do about streetlights in your community.
