Defective Bulb Tripping Ckt Breaker: How Possible ?



Hi,

Boy, this is a funny one.

Wife turned on a hall light switch last night, big flash by one of the hall
lights, and the ckt breaker tripped.

Was about 2 days since putting in a new bulb there.
Was the el-cheapo brand picked up at CVS, and made in China.

Replaced the bulb with a GE one, and so far everything seems O.K.

Question: I can't imagine how anything, like e.g., a broken filament
perhaps, can short out the circuit.
But, perhaps ?

Can anyone think of a bulb failure mechanism that might trip the breaker ?

Or, might this be just a coincidence ?

Thanks,
Bob
