Dark Sky Initiatives
When was the last time you remember seeing a starry night sky? This phenomenon seems to have diminished over the years due to the use of artificial illumination. While this may seem minor in nature, if everyone does their part and ensures that responsible lighting practices are used at their properties, everyone will be able to experience the beauty of a starry night sky.
What is Light Pollution?
Light pollution occurs when artificial light shines where it is not needed or escapes upward into the night sky.
Excessive or poorly directed lighting can create glare, reduce visibility, affect wildlife, and diminish our ability to enjoy natural dark skies.
Types of Light Pollution
Skyglow: The brightening of the night sky caused by artificial lighting.
Glare: Excessively bright lighting that reduces visibility and creates discomfort.
Light Trespass: Light that spills into neighbouring properties or areas where it is not needed.
Clutter: Groups of bright lights that create unnecessary nighttime brightness.
Why It Matters
Artificial light affects more than just our view of the stars. Light pollution can disrupt wildlife, impact ecosystems, and interfere with natural human sleep cycles.
Ways You Can Help
Simple changes to outdoor lighting can help reduce light pollution and preserve Greater Madawaska’s natural night skies.
Use Lights Only When Necessary
Turn off lights when they are not needed. Motion sensors, timers, and smart lighting can help reduce unnecessary light.
Give Every Light a Purpose
Before installing outdoor lighting, consider how it impacts neighbours, wildlife, and the surrounding environment.
Direct Light Downward
Ensure lighting only illuminates the intended area and does not shine upward into the night sky.
Reduce Brightness
Use dimmers and lower brightness levels whenever possible to reduce glare and light pollution.
Use Warm-Coloured Bulbs
Outdoor lighting should be no more than 2700 kelvins to create softer, warmer light.
Recommended Outdoor Lighting Fixtures
Choosing the right outdoor lighting fixtures can help reduce glare, minimize light pollution, and improve nighttime visibility.
Full cut-off fixtures direct light downward where it is needed instead of allowing light to spill upward into the night sky.
Dark Sky Preserves & Additional Resources
Dark Sky Preserves are protected areas that make a special commitment to protecting and preserving the night by reducing or eliminating light pollution.
Many plants, wildlife, and insects rely on darkness to forage, breed, and navigate. Protecting dark skies not only creates beautiful nighttime experiences, but also helps protect ecosystems.
Learn more about dark sky protection, responsible outdoor lighting, and designated dark sky preserves across Ontario and Canada.
