[Elecraft] LED Lamps and HF RFI?

[David Gilbert]

Even those that are spec'd as "dimmable" sometimes have disclaimers 
saying that they may not be compatible with all dimmers.  I've seen 
"dimmable" bulbs sit there and blink when used with some dimmers. In my 
opinion, there is a need for the lighting industry to resolve this, 
because right now there is no real guarantee of compatibility between 
LED/CFL power supplies and dimmers ... and nobody has a clue whether 
they will work together or not.  At best, the power supplies in the 
dimmable LEDs probably won't burn out when hammered by the chopped 
waveform of a typical dimmer, but that doesn't mean they will smoothly 
dim or won't turn into a strobe light.
