50. Any buzzing made by a CFL has nothing to do with "thousands of volts"; it has to do...

...with the inductor on the electrical filter that keeps the
CFL from putting electrical noise back in the power line.

LED lamps have the same component.

Also, if you can ever measure "thousands of volts" across
any component of a CFL, it would only be for a fraction of
a second while the lamp is being started. And many CFLs
don't even do that during start-up.

And the tungsten filaments of conventional incandescent
lamps often "sing" (give off high-pitched audible noise),
especially when they're operated on dimmers, even if the
dimmer is set to "full" brightness.
