We have no dimmers except the on/off dimmers called wall switches. ;-)
Re: LED's. I have three CREE LED bulbs in my ham shack std ceiling
light fixture with no RFI. My wife is substituting out incandescent
and bad CFL for LED's she found at Home Depot (not CREE - I think
they are GE). They also directly install in std light
fixtures. They are cylindrical in shape. Also are not bothering the radios.
I have a desk fluorescent and garage has 30w tubes which do not seem
to cause RFI. The switching PS for our new Direct-TV satellite
receiver throws out bad RFI on 2m. Fortunately, I am usually in
front of the TV most of the time it is on. I will have to try
clamp-on ferrites at some point.
I have a friend that acquired LED's from Costco and he is plagued
with RFI from them (no idea of brand or model). Definitely caveat
emptor on converting to LED lighting if you are a ham.

My simple (=cheaper) solution is to get rid of the dimmers all together.
How much is a good old fashioned light switch at the big three, $1.50,
two buck if you want a matching switch plate.
When we bought our house I replaced six dimmers. Didn't hear a peep from
"she who must be obeyed".
I have about that many CFL's to swap out for LED's. The garage
fluorescents will be a different story. They get to stay as long as they
stay radio quiet.
