Ballast Question

I just aquired a dual 250W MH and 4 55W PC light fixture. The two MH's fun off of one dual 250W PFO ballast. the 4 PC's run off of 2 more PFO ballasts, 2 on each.

My question is can I purchase any dual 250W MH ballast to run these bulbs? Or is there something else I need to know.

Also do you know where I can get one really cheap....and smaller than this PFO monster?

Thanks!!!

 

Also I am looking to get 2 - Coral Vue 250W 15000K MH - Bulbs...can I run them on my current PFO dual 250W ballast?
Do you have to match the bulbs to the ballasts?

 

You CAN NOT run PC bulbs off of MH ballasts.

 

You need to match wattage and ends for MH. K rating or brand need not be matched.

 

Thanks....I am running the PC bulbs off of PFO PC ballasts....the MH bulbs are running on a dual 250W PFO ballast.

I just basically wanted to know the answer any bulb should work just match wattage and end. Thank You for your help.
