Correct. The LED bulbs will last a lifetime (longer life than a house
fly). It is the driver that needs to be of sound quality. Therefore,
when purchasing an LED, it should be routine to ensure they will replace
or refund the entire lamp if it simply stops functioning regardless of
the failure.
One problem, apparently, is that LED bulbs deteriorate over time, so, claims
of lifetime should take that deterioration into account.
Looking up lifetime claims, I found this note:
"Contrary to the companyĒs calculations, an LEDĒs lampĒs lifetime is
properly measured as the point at which its capacity decreases by 30
percent, according to the order. LED lamps slowly diminish in output over
time, rather than failing catastrophically."

So, LEDs fail too.
They just fail differently.
Lifetime actually depends on usage, though, an actual lifetime will not
be 80 years. It's more a figure of speech.
If the LEDs stay on 24/7, then they may reach 5 years on a 50,000 hr.
claim with that % drop as you stated. If the lamps are used less than 8
hours a day, the life will increase to an average lifetime of 17 years
also including the % drop in the lamp output. Therefore, since a few are
taking my "lifetime" comment literally, that was not my intent. It's
simply a matter of expressing the potential life span of LEDs.
