We invited Dan onto Restoring Darkness to discuss wallpacks, those glaring lights you see on the sides of commercial and industrial buildings that seem to point straight into your eyes when you're driving on the road or walking on the sidewalk. As these lights are purportedly for safety and security, the conversation morphed into a discussion about the need for light at night. Dan points out that there is light needed for safely walking down the sidewalk, light to feel safe and secure, and light to know where you are. There are many nuances to solving this, but as Dan points out, we can at least start with the glare from wallpacks.
