Almost all LED bulb failures are because the power supply died due to overheating, not the LEDs themselves. I harvest the LEDs out of dead bulbs to use in hobby projects.
With Edison-style bulbs, anyway, the orientation they're mounted in makes a huge amount of difference. They're last a lot longer if they're oriented upright (base down) than in any other orientation because it reduces the heat buildup in the power supply.
