If you leave them on all the time, they last a long time. Constantly turning them on and off shortens their life span.
That is a much bigger issue with incandescent bulbs. LEDs can handle being cycled on and off several hundred times a second without issue. That is how they "dim".

This hasn't proven true in practice for me. I mentioned in the above post that I have an LED bulb that has been burning for at least 7 years without a problem, having never been turned off. The others from that box have been long gone, and the comparison wasn't even close.

That's how they make "noise" in circuits and simply being hooked up to 60 Hz AC that is already turning them on and off 60 times/second is detrimental to their durability. That's why they need extra circuitry to fix their flickering and not cause headaches. Dimmable LEDs are even worse which is why the best ones are not dimmable.
