It doesn't have to be that way though. It's a series of LED elements in a voltage dropper. Then they need to get rid of some heat.

Most of the time it's a capacitor in the voltage dropper that fails. I have cell phone chargers with the same technology that are 12 years old at this point. We need to stop making garbage components. Some of them do have LED failures, usually because they're not designed to get rid of the heat efficiently or the bulbs aren't designed to be in an enclosed fixture.
