Run way to hot. Do you have a fan on your light? They bubble from heat, the glass getting soft. MH runs at about 50PSI inside the bulb, so when you get it ti hot, the glass softens and it bubbles. That can be real dangerous, if the bulb explodes, shooting hot glass, sometimes up to 2200F everywhere.

I have 3 Sfiligoi Infinity XR6 Pendants. These are high end fixtures that are designed to run fanless. Ive had them for a few years and a couple of bulb changes each, and this is the first bulb thats bubbled. I just changed out my other pendant today, and the old bulb looked totally normal.
I will be watching the new bulbs more closely. Heat would be the only reason the glass bubbled, but I would think if it were from the fixture overheating it would have bubbled over the length of the bulb. This looks more like the "innerds" are much closer to the glass on one side of the tube that on the other. And it bubbled right in the middle of the filiment ( I dont know what its called) where its closest to the glass.
