Solutions designed to eliminate light pollution and help preserve our night sky
At DW Windsor, we’re committed to supporting responsible lighting practices by delivering the right light, in the right place, at the right time. Our mission is to provide specifiers with the tools and guidance needed to eliminate light pollution and help protect biodiversity. To support this, we offer a range of DarkSky® Approved luminaires designed to enhance the beauty of outdoor spaces while helping to protect the night-time environment.
Light pollution is excessive, misdirected, or obtrusive artificial light that brightens the night sky. It disrupts ecosystems, harms human health, and obscures astronomical observations.
Light pollution is caused by the overuse or improper design of outdoor lighting products, such as streetlights, billboards, and architectural lighting. The emitted light scatters in the atmosphere interfering with our ability to see stars as well as disturbing the natural behaviours of wildlife and impacting circadian rhythms in humans.
The brightening of the night sky over populated areas due to the scattering of artificial light by atmospheric particles and gases.
Excessive brightness or harsh contrast produced by direct or reflected artificial light that impairs vision and causes discomfort.
Unwanted artificial light that spills over from one area to another, disrupting darkness and causing visual discomfort or disturbance.
The presence of numerous and visually confusing bright lights in the night environment contributing to a loss of natural darkness.
How to prevent light pollution
The best way to eliminate light pollution is by adopting responsible lighting practices. For outdoor lighting there are several simple steps which can be taken to reduce its impact on the night-time environment without impacting on safety.
