The only difference between 120V and 240V CFLs is the configuration of the
rectifier and filter capacitor(s) on the input.

120 volt and 240 volt CFLs drive circuits mostly have the very similar
topology.

The tubes for the latter simply run at half the current of the former.

See for 120 volt CFLs.

See for 240 volt CFLs.

All 14 shown use a bridge rectifier at the AC input.
