GUEST,Keinstein | BS: Replacements for incandescent lights (83* d) | RE: BS: Replacements for incandescent lights | 03 Oct 07 |
Most dimmers don't do PWM on the AC, they do phase control. That means the AC doesn't turn on (if you're dimming) at the start of the cycle, but is delayed until some later point. This results in a horrible current waveform like ripsaw teeth. |
