Believe me sir, they are very noisy. Perhaps you should be a little more
resourceful and check your facts before you present them.
Don't ever call someone a liar unless you are capable of deciphering the
truth.
Try it for yourself.

The do make a hell of a buzzing noise! Some worse than others of the
same brand. Sure smell when the burn out too.
Anyway what I found was that if I wrap the glass shades on the fan with
aluminum foil (still allows good heat transfer) and ground it to the fan
case.... Voila! The buzzing stops.
Those suckers sure do radiate. I only loose a minimal of light doing
this. Maybe they should come with some kind of screening device/mesh
packed in the package. I really don't think I need the radiation
especially from three of the suckers directly over my head.

First I found the Chinese CFL's to be horrendous and should be reported
to the F.C.C., as if they will do anything.
Last night I had another noise source to kill, a 3 way touch lamp that
uses an SCR. I turned it off thinking the noise would go away but it got
even louder with the light off. Picked it up and looked on the bottom
and sure enough, "Made in China.". The only way to stop the noise is to
unplug it completely, making about a 20dB improvement in the noise floor.
I don't know which other things make RFI this bad but so far "Made in
China." seems to be a warning label for total crap products.

Didn't we discuss this in depth 10 years ago?

I wasn't here 10 years ago (this group), but it has gotten worse. It
seems the Chinese are flaunting *American Stupidity* and getting away
with it. You can't return these things for repair and they know it.
So why doesn't our government do anything? Political kissy face is
getting old. The more of their junk we buy the more of us they own.
