Solution to Reduce Light Pollution: 10 Easy Ways
When we start thinking about the issue of light pollution, like many other environmental issues, it can seem like an impossible problem to fix. Luckily, light pollution is technically the most easily reversible form of pollution. If you are interested in reducing light pollution, the best way to start is at home. We have 10 easy steps you can follow to inventory your home lighting to decrease the amount of light pollution coming from your home.

How Many Lumens Do You Need for Outdoor Lighting?
When installing or replacing outdoor lights, brightness of the lights (lumens) is an important factor that needs to be considered. The amount of lumens needed will depend on the application. This will range from 12-800 lumens depending on the purpose of the light.
We recommend going on the lower end when possible, this will not only save on energy costs, but it will help to decrease your contribution to light pollution. You can also add additional lights, or go with a brighter light bulb if you find you need a brighter light for your outdoor lighting.

Best Outdoor Lighting Ideas for Your Backyard Landscape.
Many people put a lot of time, money, and effort into their outdoor spaces. Lights are a great way to enjoy your outdoor living space at all times of the day. We believe that less is more when it comes to lighting. Too much lighting and everything will be bathed in a generic glow, the play of light and shadows allows for a much more dramatic effect and will allow certain areas and features to be highlighted. We have some great dark sky friendly lighting options for all your outdoor lighting needs.
