Fwd: Mercury arc vapor lamp exploding?

Does it really explode without warning? I thought the cause for the 
bulb to explode was an oberheating due to a too high power 
dissipation in the lamp (caused by an increase in current due to 
wear of the electrodes). And I believed that the lamp would start 
to flicker then because of an instable arc when this happens.

Our bulb here now has some 290 hours on its back, but doesn't show 
any flicker yet. So I should change it anyway, just in case?
