[ARC5] externally generated noise from switching controllers.

OK, Les,

It's just that this email stream started off with concern about the amount 
of RFI generated by household lamp dimmers, not that generated by the new CF 
lamps. That's why my question about dimming LEDs. My lad wants to dim LEDs, 
too, and I have told him the dynamic range is very small - perhaps 3:1 at 
most.

In response to Brian's:
