The problem with led bulbs is that they are build to operate at their limits. It's still within spec, but just barely which is why they break so quickly. If you would reduce the current by half they would last for decades.
But of course Big-Light doesn't want that, so after the initial well-build led bulbs became standard they switched to cheaper designs with less internal led modules for the same brightness.
As I said, the simplest solution - better cooling.
