So I'm talking to my friend about dimming a 120V, 500W light. One version of the circuit is to use a triac and a diac and a controller.
**broken link removed**
Another thing I was thinking about was to throw a 1MΩ potentiometer into the mix and dial down the voltage on the light.
So I guess the question is, what would be the disadvantage be, if any, to just using the pot to control the amplitude of the voltage to the light as opposed to using the triac to control the pulse duration?
