comment What debuzzing coil should I use to get rid of lamp hum?
I tried a GBPC3504WDI (same as your suggestion, but rated up to 400V) and the buzzing became even louder. The doubled frequency is perhaps closer to this bulb's resonant frequency. I will scrap the rectifier and might try the coil instead.

This means I'm giving DC voltage to the bulb, right? Do I need a smoothing capacitor, or will the full-wave rectified sine waveform be enough to stop the buzzing?
