How true!!  I tested a "LED Garage Light", of course, from China bought
on Amazon.  It measured some 30 dB over the FCC specification for radiated
emissions.  Conducted emissions were even worse!  Need I write more??!!

It was loaned to me for a test as when it was on it wiped out the wife's
listening to FM radio.  AM radio was absolutely hopeless, even for local
strong stations.  FCC doesn't give a rip (Or maybe that should be "RIP").
