They are a good deal and I had replaced at least six. My assumption was it's just a manufacturing defect since it's low cost and mass produced. And I'll buy the same ones to replace them.
Also note, these are spotlight LEDs that in the past were halogen, and not your standard sized lightbulbs, which are probably a few generations ahead in terms of manufacturing.
