SFX bulb tolerance for vibration...

[PropellerHeadCase]

Anyone know what sort of tolerance bulb in effects lighting have for vibration? For example if the unit was in the same super-structure as a sub, and so on.

If its an ordinary bulb then not much at all, I had 2 ssc-2 's and they liked to blow bulbs all the time turns out one of my speaker pole legs was touching lighting truss and the vibration was taking them out.
I've heard that discharge bulbs dont have this problem though as they have no filament to damage.

Good to know, thanks.
