[RFI] LED streetlights - Lumenistics

[Dave Cole]

I was able to work with our City engineer prior to LED streetlights 
being deployed...

Myself and another Amateur tested by sitting under each of the the test 
lights, and found nothing on any brand.  We listened on 160, through 2 
meters.  If I remember correctly, there were maybe 4 or 5 different 
brands.

This was several years ago, the city has converted fully to LED, and no 
issues so far...

73, and thanks,

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..
