[RFI] LED streetlights - Lumenistics

[KD7JYK DM09]

"I remember years ago when municipalities replaced incandescent traffic 
lights with LED lights to save money. They discovered that in winter the 
snow would cover and block the lights since they didn’t generate heat 
like their predecessors."

Another issue, both with LED traffic signals, and automotive lights, 
which personally bugs the crap out of me, is the hot/cold of just the 
weather alone causes the solder joints to fail quickly, and I see lamps 
with various blocks, chunks, stripes, et cetera where a section no 
longer illuminates.

One would have imagined this to be resolved in initial testing, but I 
still see it on a daily basis, after, what, some thirty years of 
technology evolution?
