Re: [RANT] Commercial Electric 4 in. Brushed Nickel Recessed LED

You got 75%. A sampling of four is statistically not sufficient to conclude that 75% are bad in general. I also assume that you inspected the lamp after it "failed" to exclude problems in wiring and in the socket.

I am not aware of any gun that is 100% reliable. Can you point me to a source that shows relevant data to confirm your statement? (Then multiply that with the mental stability of the gun owner and you get something that's even further from 100% )

The box that the lamp comes in proudly states "25 year lifespan". To me, that means it should last 25 years, not 2 hours.

I shoot lots of types of firearms and, other than some dud ammo, I've never had a gun malfunction totally. After hundreds of thousands of rounds, never had a gun explode in my face. If guns were as unreliable as these lights, I would not be here today.

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.
