What we have here are the internal structures of a 450 lumen LED bulb (left) and an 800 lumen LED bulb (right). And how did I get these plus 2 others? By simply installing them in the 2 gooseneck lamps I recently bought. For some reason the glass bulb spontaneously shatters at the base and falls off. I don't have to touch or move the lamps. I hear this “clink” and the bulb falls off. I have no idea why. And the LED's continue to function. It is really weird.

Perhaps a defect is being introduced during manufacturing, e.g., when attaching the base. With some thermal cycling, the glass initiates a fracture and the rest is, "clink," bye-bye bulb.

I've not seen such a thing happen, either. At least they're LED, so they'll just keep going regardless. I assume the shade on the lamp provides sufficient dispersion of light in lieu of the frosted glass covering.

Yes, I've noticed no difference in the light dispersion so I'm going to keep using them.
