Most dimmers can not handle inductive loads,only (mostly) resistive loads. You may also have noise on the wall wart output,due to the 'chopping' of the dimmer. ••• More options Share leadbelly Member Joined 2002 2010-09-14 3:00 am #3 2010-09-14 3:00 am #3 It'll probably work OK if you use the expensive dimmers intended for fluorescents and not the cheap ones for incandescents. Of course you haven't said what you are trying to achieve so it's hard to say if it's a good idea. ••• More options Share star882 Member Joined 2007 2010-09-14 3:49 am #4 2010-09-14 3:49 am #4 A normal dimmer won't work with inductive loads, but a ceiling fan speed control will. ••• More options Share hitsware Member Joined 2002 miller-music.one/ 2010-09-14 3:51 am #5 2010-09-14 3:51 am #5 star882 said: A normal dimmer won't work with inductive loads, but a ceiling fan speed control will.
