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.
