These are soft glass and they don't like sudden temperature changes of the thermal expansion. Hence, that is why there are bunch of warning message on those high power bulbs and Mercury/Sodium/Halide bulb packages.
sometimes we've experienced random bulb explosions....this time i just thermal shocked the glass by cooling it off suddenly while it was hot....those other times we had bulbs pop for no apparent reason.
Incandescent explosions happened regularly at EOL in my parent's home when they used them (more then 15 years are everywhere, except bathroom, some kind of fluorescents), but the glass shatter everywhere...
@A-lights: Close filament area they are...
Seems more like air had entered this lamp, becuase of the strange blackening on it.
This lamp exploded, because you wiped it with a wet cloth, and operated it, when it was wet.
Most type of glass except borosilicate type glass, shatters when they are exposed to thermal differences.
