If it keeps failing, I would put in a wall dimmer to cut the power to the bulb a bit.
I recall T-Al's neighbor had hot wired to the utility to power their grow operation, and overloaded the feeds to the point of smoking. Perhaps somewhere along the way, someone on your feed complained of low voltage, and the utility increased the voltage to that feed, and never brought it back down when the grow operation was detected?
If you have high voltage, you want it fixed. It can affect a lot of things, but filament bulbs are very sensitive to delta V. IIRC a 10% increase gives less than 50% life.
I'd put in an LED rated dimmer in either case. Dimming is a nice feature and will increase bulb life (I think halogens need occasional time at full power - something about the halogen depositing on the glass and needing to be 'burned off').
130V bulbs would help but I say fix the source.
