They really do fizzle out with annoying regularity at 240V

The ones I had trouble with were those that are on a lot of the
time - the longer they're on the thinner the filament gets and
more prone to turn-on blowout

Something I considered, as 120V filaments are thicker, but two
bulbs isn't always practical. I may yet look into it, as one or two
fittings could be changed fairly easily
