Incandescent bulb life is very much a function of voltage applied to the filament. This relationship is not linear. While lumens output is directly proportional to current consumed, a small reduction of voltage will give a very large increase in service life.

I don't remember the ratios any more, but I seem to recall that a reduction of 10% in voltage would increase service life of an incandescent bulb by a factor of six or more.

If your kitchen light bulb is failing as often as once a month, I suspect problems with your wiring, perhaps an arcing current in the switch, fixture, or wiring; or for whatever reason perhaps the voltage to that fixture is too high. Over-voltage has as much effect on bulb life as under-voltage, but in the inverse direction!

Put a meter on that light socket and see what is going on before you blame the bulbs themselves.
