we have small flouro bulbs to that can take the place of the tungston globes

I've seen small flouro bulbs for sale as replacements (I guess they burn out too) but I haven't seen a torch that uses them.

I cut apart a dead compact fluorescent globe. They have a lot of nice electronic parts in there. HV power Mosfets and capacitors, tiny transformers and coils. Their power oscillator operates at 40kHz.

Your mains has twice the voltage as mine. Our mains voltage is so low that the filaments in the ends of fluorescent lights must be used to start them. The filaments waste power all the time the lights are on and burn out. Fluorescent lights here don't start when a filament is burned out.
