It's somewhat of a known problem space. Tackling light pollution boils down to easy steps, you just have to be mindful in design... - Only be on when needed - Only light the area that needs it - Be no brighter than necessary - Minimize blue light emissions - Be fully shielded (pointing downward) Light pollution is (IMO) driven by lack of knowledge of the problem & solutions, a perception that lights = wealth/luxury, and the low cost of electricity.
