Maybe you've noticed that as LED retrofit light bulbs have fallen in
price,
their rated lifetimes have gotten shorter. The early ones were rated for
50,000 average hours; many now are rated for 10,000-20,000 hours. The same
thing happened with compact fluorescents, which quickly declined from 10,000
hours to 6,000.
FWIW I haven't noticed that the LED bulbs I've purchased have lasted
longer than the old incandescents so I pretty much don't believe
anyone's rated lifetimes.
