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

Subject: Re: [RFI] LED streetlights - Lumenistics
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

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?
