I think these lamps are one of a kind tbh, work of art

Looks like the FEC don't have a thermal cutout, which make sense, since it don't contains moving parts. But I think I still see strips near the arctube that looks like bi-metals?

There is a wire in contact with the arc tube which moves away when the lamps warms up.

So how the ignitor working during a hot restrike?

There is also a bi-metal switch on the other side. Takes about 10 minutes to restrike.
