A cheap dimmer, well that sucks! It is most definitely NOT the light that
is buzzing, but the dimmer. I can hear it clearly when I put my ear to the
wall next to the switch. Damn, I'll go shopping around tomorrow then.
On a second note, aside from the buzzing, is there anything dangerous about
its condition, or is it simply buzzing because of cheap construction. I
believe I understand how dimmers work, is it possible that the lights might
also affect how it performs.
