Also it is possible for one SCR to dim 2 fixtures, just ask how ETC Dimmer Doubling works.
Ah, gotcha. Though they'd be double triacs or double SSRs, right? Or maybe double paired-SCRs? In any event, that makes more sense now.

I've always wondered how they did dimmer-doubling. I've thought of a few crazy ways it might work, but never actually researched it.
