Protecting the night sky
The Town of Huntsville is committed to becoming a dark sky-friendly community, a place where the natural nightscape is protected and cherished as part of our shared heritage. In 2016, Council passed the Outdoor Lighting by-law aimed at reducing light pollution and preserving our view of the stars for generations to come.
With a ten-year transition period set to wrap up in 2026, we’re now moving into full implementation and enforcement of the outdoor lighting by-law. We’re working closely with residents, businesses, and visitors to make this change as simple and effective as possible, while also helping to safeguard the beauty and serenity of our night skies.
What is light pollution
Light pollution is the human-made alteration of outdoor light levels from those occurring naturally. When we over-light, fail to use timers and sensors, misdirect or use the wrong colour of light, we negatively affect many parts of our world.
Harmful effects of light pollution
Light pollution can seem subtle, but its impact is real — on wildlife, on human health, and on our ability to experience the quiet wonder of a starry night. Together, we can protect what makes Huntsville special and ensure our skies stay dark, clear, and full of stars. Learn about four effects of light pollution:
Destroys critical wildlife habitat
Plants and animals depend on Earth's daily light and dark cycle to govern life-sustaining behaviours. Research shows that artificial light at night has adverse and even deadly effects on many species.
Wastes energy and money
Most outdoor lighting is wasted. This energy waste increases greenhouse gas emissions contributing to climate change and wastes billions of dollars each year.
Robs us of our night sky heritage
Our ancestors experienced a night sky that inspired science, religion, philosophy, art and literature. Now, millions of children across the globe will never know the wonder of seeing the Milky Way.
Harms human health
Studies indicate that artificial light at night negatively affects human health by increasing our risks for obesity, sleep disorders, depression, diabetes, breast cancer and more.
Learn what steps you can take to limit light pollution
Transitioning to dark sky-friendly lighting is easier than you might think – and it doesn’t have to come with a hefty price tag. Upgrading to fully shielded lights that direct light downward can be done with minimal effort and cost. Many affordable options are available locally, ensuring your outdoor spaces remain well-lit and environmentally responsible.
Make meaningful change in the community by reducing your light pollution in three simple steps:
Step 1
Learn about responsible outdoor lighting
Discover the five principles of outdoor lighting. These principles ensure outdoor light is only used when and where it is needed, and in ways that reduce light pollution and its harmful effects.
Useful
Use light only if it is needed. All light should have a clear purpose. Consider how the use of light will impact the area, including wildlife and their habitats.
Targeted
Shield and aim your light so it only falls downward and where it is useful.
Low-Level
Light should be no brighter than necessary to save money and reduce glare.
Controlled
Light should only be on when needed. Use timers and motion sensors.
Warm-Coloured
Warm-coloured light causes less skyglow. Use amber-toned lighting when possible.
Step 2
Assess your outdoor lighting
Use the following handy check list to review your lighting.
Step 3
Replace or adjust your outdoor light fixtures
Before you get started, first ask if the light is necessary. If it is, replace or adjust each outdoor fixture to comply with all five principles.
Select Adequate Shielding
Choose a fully shielded fixture that directs light downward.
Choose the right lumen level
Select an appropriate lumen (brightness) level with the total lumen output below 1000.
Use Timers and Sensors
Place necessary outdoor lighting on a timer or motion sensor to ensure it is only on when needed.
Opting for Warmer CCT's
Select a luminaire or bulb with a warm or amber-toned correlated colour temperature (CCT) - 2700K or lower.
Supporting a Transition to Dark Sky Lighting
The Town of Huntsville will continue to provide educational resources to help residents, visitors, and businesses understand the importance of preserving a pollution-free night sky.
