[Premium-Rx] "quiet" dimmers

[Brooke Clarke]

Hi John:

Another option is discrete levels rather than continuous adjustment. For 
example if you switch two lamps is series they get much dimmer, last 
longer and don't generate any RFI.  In a similar way you could switch in 
power resistors.  I think you will find that you really don't use all 
the possible light levels, but rather have bright, and a soft mood level.

The power resistors don't necessarily need to be in the wall box,  but 
could be above or below it where there's more air flow for cooling.

Have Fun,

Brooke Clarke, N6GCE
