The other part that can destroy lamps prematurely is the ballast. Although I doubt it is at fault because the ballast operates with high voltages and if a part is bad on it, the ballast usually will not work again. Secondly, the high voltage will start out high and after the lamp is started the voltage lowers to normal operating voltages. If this fails to lower then the lamp will be destoryed in a matter of hours not months.
