I'm disappointed to see these lights being expanded throughout Springfield.  They are completely unhooded and will contribute to light pollution which is the cause of all kinds of health and environmental problems.  Please refer to American Medical Association recommendations, the International Dark-Sky Association (https://www.facebook.com/IDAdarksky/?hc_ref=NEWSFEED&fref=nf), and Chicago's recent problems with new LED lights (https://www.wbez.org/shows/wbez-news/experts-warn-of-health-risks-as-chicago-switches-to-led-streetlights/c3729447-e95c-4fb6-a658-5bb0d5b8c7e5?utm_source=facebook&utm_medium=referral&utm_campaign=Web-Share).
