Singing light bulb on dimmer switch
Most light bulbs hum loudly when dimmed via a dimmer switch. A few are ok, because they contain extra filament supports at critical positions.
My hanging (swag) kitchen tiffany-style light takes a G40-150w bulb. It hums badly when dimmed.
(1) Is there a brand of G40-150 bulb that does not hum when dimmed?
(2) Alternatively, is there a small, in-line filter available, or a filtered, table-top dimmer switch, that would create a smoother short-duty-cycle output than the intermittent, alternating square-wave created by a typical dimmer switch? Would that be safe for a household lamp application? Would that eliminate the audible humming?
