I've heard the explanation that they don't dissipate heat well and their lives are shortened because of the fixture they're placed in. With incandescent bulbs, heat wasn't the issue it is with LEDs.
And the ability to dissipate that heat apparently depends a lot on the orientation of the bulb (socket up or down), enclosures, etc., so you can end up replacing LED bulbs in certain fixtures more frequently than others.
This is most of it. If they're facing up (typical lamp), they'll last for years. If they're facing down (ceiling fixture), especially with a shroud around the bulb, they won't last much longer than an incandescent. The control chip burns up if they get too hot.
So just put cheap ones in the fixtures that'll kill them. You can get decent bulbs for less than $1/per.
Juat don't buy the ones that say not to use in an enclosed space and they should do fine in any fixture.
Cheaper bulbs, definitely. I had a corner display cabinet I tried to switch over to using an LED bulb; the compartment for the bulb was nearly sealed and also lined with reflective materials, so the exterior got hotter to the touch than it ever did with an incandescent bulb. Damn thing started flickering and malfunctioning a few months in. Tried another LED bulb and the same thing happened only on a slightly longer time frame. Finally just gave up and went back to an incandescent bulb.
