The circuitry gradually failed within months, one LED segment at a time. So, even though the LED’s may be touted to last a long time, the power supply may not.

I design circuitry for a living. Trust me, there is only one power supply in the light bulb. If it failed all of the segments would go out. What you are seeing is individual segments failing and that is interesting information.

I was surprised too. The segments were shaped like pie slices. I think there were at least four of them.
