What are the physics of the mechanism(s) that would cause a INSTEON
Lamplinc dimmer (TRIAC output device typical of residential US dimmers)  to
'take out' lamps?

And why, as Dave thinks,  is this "more likely" than the well-known
phenomenon of a current surge owing to tungsten arc when the filament fails
causing the TRIAC in the dimmer to fail?
