No, and there are advertisements that show that led lamps still melt snow!

  Is  there a problem with  snow  build-up on  the new  LED  lights. ?
   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 ?

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..  

Good luck

Our city (Colorado Springs) is installing LED street lights with some new type of controllers.

I am not sure, but I believe these are made by a company named Lumenistic (of Boulder, Colorado).

Here is link to recent news article:

It is the microprocessors with potential for RFI that I want to know about.

I'll probably take my Tecsun PL 660 over to where they have installed some of the new lights and take a listen.

Anyone have experiences along these lines?
