Well, I took the bulb back and the shop owner just said he'd seen bad bulbs before. nothing like this one but went upstairs and grabbed a new bulb and off I went.
I did send an inquiry to Hydrofarm regarding what would/could happen to a bulb from a bad ballast. response below.
"
Unless the bulb is physically broken the gas won't escape. Even if there is a leak and the gasses escaped the bulb would immediately burn out. The ballast should not cause this. It is more likely an old bulb or one that was defective to begin with.
Hope this helps.
Happy Farming!

Everything seems to be in order now. Just waiting for the newly cut clones to grow up enough for flowering.
I cannot wait to see the difference in the 2 strains I grew under a 400 hps in comparison to the new 600.
