text: I am dismayed that local government would  replace our street lights with LED ones 
  after knowing about the AMA report...decreases melatonin needed for sleep.  Melatonin
  is also a powerful antioxidant needed for cellular repair.  Lack of melatonin is associated 
  with -increased obesity, increased cortisol levels,  diabetes, etc. The lights are 
  also disorienting to birds and insects (bees.)  
  
  Recently, I have heard many friends talking about not sleeping well...having trouble 
  going to sleep and staying asleep...myself included.  These lights are almost blindingly 
  bright...like a spotlight.   Is there any way they can be toned down?
