Hi Jeff, Phil. * First I know nothing about incandescent bulbs.

I'm still learning (mostly from my mistakes).

It's definitely my mistakes that have taught me the most.

(my latest f-up had to do with short ultrasonic pulses,
and 1/4 wavelength anti-reflection wave-plates...)

I've no problem with your marquee story. Sometimes folk-tales about
rocks falling from the sky are correct.
The data point I offer to Phil is that bulbs fail when you turn them
on. I see no reason why that can't be 'played backwards'. There most
be some GE, Philips, (other) report that documents turn on failure.

I blundered across this video on tungsten filaments.

While it doesn't touch any of the issues previously mentioned, it does
include some interesting info on how the filament is made and its
structure.
