We have a light fitting with three lights that take a smaller type of

need to call an electrician?

Thanks for any help.

Several factors can cause short life.

Heat, especially if the lamps are in an enclosed fixture
Vibration, from machinery or sometimes someone walking on the floor
above a ceiling fixture.
Moisture. This is also a killer, it does not take much.

?? How would moisture get into the lightbulb, or make a difference
from the outside?

Poor connections. If the contacts of the fixture are corroded or maybe
lost their "springiness" the lamps may not be making good contact.
