No........I don't have X10's. The fan has no external switch, only pull chain. I do want to dim the chandelier. So, according to your message, I just have to buy a X10 PRO-XPDF dimmer module? Can I get that at a big box store? Will they know what I'm talking about, cause I sure don't.
If you don't have X10 now, you might want to read the X10 wiki to get more of a feel for the system.

X10 remote control's forte is controlling many devices, not just one (although it will control your chandellier easily as long as it is 300 watts or less). X10 is like Lays Potato chips, you won't stop with one. Lowes, Home Depot, etc carry DIY remote controls for ceiling fans, perhaps they have one for chandeliers also.
Back to X10, the X10 PRO XPDF is the "receiver" which will actually supply power to the chandelier. You will also need a "controller" which will transmit the ON, OFF, BRIGHT, DIM commands. X10 controllers come in many flavors: wired, plug-in, wireless, wired with timers, etc. The X10 PRO site
http://www.x10pro.com/ has the XPDF and all the flavors of controllers.
The X10 "soft porn" site
http://www.x10.com/ has receiver, controller "bundles" at discount prices along with the X10 home automation and X10 security products, sprinkled with bimbos, floozies, and trollups.
Radio Shack used to carry X10 products, but discontinued, as did Lowes. Home Depot may still carry X10 remote control/automation products. eBay and the X10 web sites listed above are good sources.
