The box that the lamp comes in proudly states "25 year lifespan". To me, that means it should last 25 years, not 2 hours.
Yes, if you buy 1million such lights you will see that they average 25yrs life. Some will die after 1hr, some after 1 day, some after 1 yr and some may last 100yrs. It's not a guaranteed life, it's an AVERAGE life.
If I put on my engineering hat, yes, I agree, that's largely how MTBF is calculated--an average. But the lawyer side of me says a product ought to perform up to the advertised claims.
