I thought LED bulbs were supposed to last for many years. I put on in my
barn about 2 years ago. It's on all the time as a safety light. It only
uses about 5 watts so I'm not concerned about energy usage. (25W
equivlent).

All of a sudden it has gotten real dim, and it flickers. I'm wondering
what caused that? I know it cant be fixed and needs to be replaced, but
I did not think the LED bulbs were supposed to fail for many years.

When I shut it off, it stays lit for a few seconds after the switch is
OFF, so I imagine there is a capacitor in it, but obviously that cap is
working..... But it's less than half as bright as it used to be, and
flickers.

try it in a different socket.

Well, fellas...... This sad story sorta is like life for us old farts.
We last [hopefully] fer many years ourselves, ya know. Then, one day we
start gettin' a might tuckered out, if ya follow me. We start gittin'
dim ourselves, and in a way you could say we, too, start to flicker.
Eventually we just kinda wink out all together, ya know; and it's--like
they say--the Final Curtain. Folks left behind, they might cry a little
at first; but soon enough they forget about us. In a few more years
nobuddy even remembers us. Such is the temperance of existence.

Amen (and boo hoo)

A LED is a Light Emitting Diode. As such is only
works up if current is supplied to the correct
side of the circuit.

For Alternating Current as used in a barn the AC
must be "rectified" so it all goes the same way.
This being the case, the LED bulb probably has a
failing rectifier (which also consists of diodes)
in its internal circuitry.

I use 12-volt DC LEDs in my fine yacht so I don't
experience this lubberly LED failure like you rabble
who dwell ashore in your foul smelling hovels.

Do you even know what a full wave bridge is?
