Hi Joren,
It is a little late at night for me to remember the load type the
dimmer sees (I think inductive).
However, I tried this once (to control pin spots) and was unable to get the dimmer to run them. Some people have told me that they can, but I wonder if that is just using a dimmer to switch the unit on and off. In which case you should use a switch pac as I am sure that it isn't good for your dimmers.
Not sure that this is of any help
