   FWIW, the "regular" X10 controllers can dim from 100% to 0% but they   
   don't want to go the other way; a lamp that's off can only be set to a   
   dimmed brightness by first turning it on (=100%) and then dimming it.   
   Once it's on, of course, the dimming setting can be adjusted up and   
   down; just can't go directly from off to, say, 10%.   
      
   Note that the controllers I'm running are pretty old and the newer ones   
   (or other models) may not have this limitation.
