Well its a goof many years since I was a lighting engineer. We used to make two main types of lamp 1000 hour and 2000 hour. The only difference was in the thickness of the filament. The 2000 hour lamps consumed slightly more power, but lasted twice as long.
Most failures were due to mechanical vibration or to magnetostriction. We also made traffic light lamps, which had more supports, and were less prone to vibration. Where lamps are used in pendant fittings, and there are frequent failures, simply shortening the flex a little can improve the lamp life by changing the resonant frequency of the installation. Having tap dancing elephants in the loft can also shorten lamp life.
Magnetostriction is due to the filament having a coiled coil, which contracts when a current flows through it.
We used to have a lamp shaped like a radio valve, which had lasted thirty years before I stupidly dropped it whilst moving house. I never checked its current consumption, but the light output was a fraction of the 1100 lumens you would get from a normal 100 watt lamp.
