I currently use CFL with my setup and have not had a problem. You just need to determine where you want to use the CFL's before you buy the modules. I have 2 CFL's controled by one switch so I used an appliance switch, then I have two other CFL's controlled by socket rocket's (never had a problem). I also have an aquarium which uses flourescent tubes, and used plug in appliance modules and have not had a problem. The key is to use modules which do not dim or appliance modules. Since, these modules have the extra wiring needed to bypass CFL's interference.
