[RFI] LED streetlights - Lumenistics

[Gary K9GS]

Snow is not an issue with LED streetlights since they do dissipate quite a bit of heat as David pointed out.Snow, however, is an issue with LED traffic signals. Streetlights stay on for hours, plenty of time to get warm. Traffic signals are constantly turning on and off.73,Gary K9GS

I  ask  because , I  assume  there  is  no heat  to  melt  any  build up of  snow. .  Before  the change to  LED lights, did  snow  block  the  lights ?                                          							 Bill / w2ay ***************************************************************************The entire city of Bloomington, Minnesota has LED street lights.  There is one less than a half block from my house.  The Mall of America is six miles East of me and the entire parking ramp is LED lighted.  I was also concerned when they started the project.  So far I have not noticed any increase of noise from these lights.  They’ve been in place now for a few years.  They save on electric power and the old street lights used to be a problem when the automatic switches failed, those were operated by light sensors on top of the old street lights.  I think there is a similar setup with the LED lights, but so far have not failed..
