Why does the failure of a lamp usually happen just after it's turned on?

Something to do with resistance I think...

I believe the resistance is lower when it first turns on, so the current is very higher due to v/r = I. The higher current can lead to it failing, as it is too high. I think this is correct, though I may have it the wrong way around.
