Assess the Lighting Around Your House
Poor lighting not only creates glare and light pollution but also wastes enormous amounts of energy and money. Take a few moments to check your property for inefficient, poorly installed, and unnecessary outdoor lighting.
Use Dark-Sky-Friendly Lighting at Your Home & Business
Look for the International Dark-Sky Association (IDA) Fixture Seal Of Approval on any outdoor lighting you buy. We have a searchable database of lighting products certified to minimize glare, light trespass, and to reduce carbon emissions.
Chat With Your Friends, Family & Neighbours
Solving local light pollution issues is as simple as chatting with your neighbours. Use some of our resources like our General Brochure, “Losing the Dark Film” or Mobile Apps to help spread the word.
