What brand of bulb is it. We find that most brands will buzz, but Philips
bulbs don't, or at least not as much.

I have a 100W globe style bulb attached to a simple 2-way dimmer. The
thing (the bulb) buzzes like crazy on anything other than full on and
full off. 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
