I have two lamps which use these big 300W bulbs that I am dimming with Insteon LampLink modules. They buzz quite a bit, and I previously asked a question about reducing the buzz which led me to switch to these large, rough service bulbs. However, the buzz is even louder now!

I've read (here and here and elsewhere) that I can wire a Lamp Debuzzing Coil (LDC) in series with the load (on the hot wire between the lamp and the dimmer) in order to smooth the onset of current during the switching (i.e.: waveform mutilation) and reduce the hum.

Will this work?

What product should I use? Is there something suitable at Digikey?
