I have a 100W globe style bulb attached to a simple 2-way dimmer. The thing

You can even see the filament flapping in the inert breeze.

Is there no way to fully remove this buzzing? I know a little about the
higher speed switching techniques involved, and I also know about the wave
deforming that some do. But is there not something foolproof? Seems like
something that should have been solved by now.

Thanks



Maybe a heavy duty bulb, which has additional filament supports in it,
would be quieter?

You could always add a bridge rectifier and filter cap to the dimmer's
output so the bulb runs on DC. G
