Brown Spots on New MH Bulb

[-Logzor]

New XM 20k 250w DE MH. Is this normal?

IMO no. all the ones i've gotten have been clear... Maybe you got a used bulb or a tested one?

Yeah it totally looks used! I contacted DFS and they are sending me a new one. Not sure how this happens, what's funny is the bulb I pulled out of my fixture looks brand new and this one looks like it's been used for years, the outside is all dusty. I bought a used MH fixture about a year ago and haven't changed the original bulbs until today.

almost sound like maybe someone at DFS got a creative "swap" if you know what i mean...

Would have been easy! Free MH bulbs for life!

I think they test Fire all bulbs at the plant when they make them. Mine will always have some burn showing but not that much.

That makes sense to ensure the bulbs work. This bulb looked dusty like it had been in a fixture for quite some time. I have it up and running until the new one gets here. Seems to work OK.
