It's all in the lumens.
After a bit you get used to how bright x lumens is and ime they're fairly consistent (possibly not if they're cheap Chinese ones)

The leds might be ok for a flasher beacon on the moon for 100 years but the driver circuit always goes puff.
I think the MTBF for LED's is probably quite high, if you buy the filament types then the driver is very simple and will probably last forever - but then it has more LED's so who knows.
My first LED bulbs are probably ten years old now and still going strong. I have around 100 bulbs in total and the few failures I've had have been in the first week or so of life so well at the start of the 'bathtub curve'.
I'm quietly confident that most will outlast me.
