Help - need 250W ballast

[Werbo]

So 2 weeks ago just before I leave to go to the ferry on vacation I check the tank one last time and only one MH light is on. WTF!!! Could have been worse ... Like the ballast blowing a day later. So for the last two weeks while I was away I've only been running one fixture mounted in the centre. Gotta get this fixed ASAP.

Does anyone have a 250w hqi ballast that is compatiable with lumenmax elite pendants/cords?

Let me know if you have something.
Thanks
Tyler
