Submission + - How to set up non-obnoxious outdoor lighting?
An anonymous reader writes: My neighbor recently complained about my outdoor floodlight shining in her window. While trying to address this problem, I read an essay about the tragedy of light pollution, and started to think that this is a much broader issue. With all the new lighting technologies out there, this may be the right time to rethink lighting — both indoor and outdoor; public and private. I solved my problem by replacing the floodlight with a spotlight, but I also considered installing a colored light. What are some strategies for illuminating what we need to without casting excess light everywhere and inadvertently blinding our neighbors or keeping them awake?
