I would be interested if someone could verify that if you placed a large amount of this type of lighting in your home that it did not play havoc with your X-10 powerline signals.
Fluorescent lights in general do not play very well with X-10. I have no idea about "compact fluorescents" though.
I have replaced incandescent bulbs with fluorescents in about 111 fixtures so far. Several of the fixtures have multiple bulbs so the total bulb count is a bit higher. They are a mixture of CFL, Circline screw-in (miniture magnetic ballast) and standard magnetic ballast fluorescents. Haveing a large quantity of fluorescents has not impacted X-10 signal quality in a general sense; ie no system wide signal suck or excessive line noise issues beyond what I had with incandescent bulbs.
Some specific points:
Do not use dimmable CFL bulbs from a company called TCP. They put a huge amount of noise on the line. Once you dim one you can never brighten it again because the line noise kills the reception to the module controlling it.
On the other hand, Phillips dimmable CFL bulbs work great. No line noise and no audible buzzing even when they are dim.
Appliance modules will cause some CFL bulbs to flash when off due to current leaking through the "local control" circuit. Disabling local control will not fix the problem because the current path still exists. The circuit in X-10 brand 2-way modules is different and sometimes you can solve the problem by using these modules even if you don't use the 2-way feature for anything.
Relay switches do not have local control circuits so they do not have the flashing problems that plug in modules experience. Be sure to use switches that have a real relay and NOT an SCR used in switch mode.
Do not use INSTEON appliance modules with any kind of fluorescent light. The local control circuit allows much more current leakage than previous X-10 modules and they go into self-destruct mode if connected to to any kind of magnetic ballast. It is not clear if they are dangerous when connected to dimmable CFL bulbs but I would avoid them until the issue is resolved.
