With the potential of arcs being struck in gas filed bulbs and electron
emission in vacuum bulbs, I wonder what the maximum voltage design is?
I've seen sealed beam headlamps in a car burn out and strike a bright
purplish arc for a second when the voltage regulator failed. Given that, 240
volt lamps must be pushing things a bit even in normal operation, yet they
are quite common in countries with 240 volt supply.
