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. Ithums 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 afiltered, table-top dimmer switch, that would create a smoothershort-duty-cycle output than the intermittent, alternating square-wavecreated by a typical dimmer switch? Would that be safe for a householdlamp application? Would that eliminate the audible humming? - David
