Both Eugene and Springfield have recently changed the street lighting to LED (blue.)  After the
AMA's warning many cities are re-thinking their street lighting and changing to an amber-colored
light.  
I thought the information about strong lighting (LED is a exceptionally glaring,bright light) 
making trees confused and reluctant to lose leaves was very interesting.   Eugene and Springfield
both recently replaced street lighting with LED lighting and many of our trees still had their leaves
in December.  In an interview in the RG with an arborist,  it was said that the extra weight of the leaves being on the trees with the freezing water was one reason the ice storm did so much damage to them.  If this an event
of this damage ever happens again perhaps Eugene and Springfield should re-think the street lighting and consider something  less bright.
