RFI from LED "lightbulbs?"

I'm figuring someone here has probably tried out some of these LED  
lightbulb replacements. For all of the reasons discussed previously,  
I'm not a particularly big fan of CFLs, and have enough trouble with  
RFI from everything else in and near my house without adding more.

Do any of you have a sense of how noisy the drive circuitry for these  
LED lightbulbs are? I'm assuming that the more featureful they are,  
the more logic they include, but I haven't seen much commentary yet  
about EMI/RFI, in contrast to the CFL horror stories.
