Figuring out why this LED light bulb failed after one year.

Need tools? Here's a video showing what I use (with links!): https://youtu.be/MLK649c1_fM After tossing a few of these in the trash due to failure over less than a year, I was very curious what exactly was going on inside. I didn't think that the electrical components inside were actually failing, and it turns out I was right! It was actually a mechanical fault that caused the failure.
