exploding bulbs dl2

Hi there,

There are four of my dl-2 now on a theater tour. 5 minutes for show time 1 of the dl2's went down en 2 minutes later a second one stopped working. The next day i've been there for troubleshooting and in both units the bulb was exploded.

I think it's pretty strange that 2 bulb explode a couple of minutes after each other. Any suggestions what could have happend ??
