I believe light dimmer RFI can be quieted down quite a bit by inserting an RF 
choke in series with the lead going to the lamp and also between the dimmer 
and the power input lead. Also some 1-2KV Rated  .01 Disc ceramics across the 
dimmer input-output sides to the ground line may help.  I bought some small 
ferrite toroids to wind a few chokes on but never got around to testing them with 
my dimmers.  If you want to try inserting some chokes be sure they are rated 
to handle the current which would be about 1 amp for a 100 watt load. A couple 
of 1/2 inch toroids can be tucked into a standard wall box along with the 
dimmer. 73 Todd WD4NGG
