I am now seeing LED bulb failures. A total of 6 so far, and every one of
them is not the LED's but the power circuit.
I run them through a band saw to remove the "pingpong" plastic dome and
remove two screws and the flat LED PCB
Simply unplugs from pins on the power circuit.
The LEDs themselves are always good.
I use the LED circuit board as-is in other lower voltage lighting
projects.
My experience is similar. The cost-cutting is going so deep that the
near-junk parts do not last. The same thing happened to compact
fluorescents. You don't get the promised life... not because the
fluorescent tube fails, but because the electronics that drive it fail.
Luckily, you can easily replace the failed circuit in an LED light with
a simple series resistor and capacitor.
