Digital Ballast and Dual Arc?

[Iceberg420]

I just inherited some growing equipment from a bud who was never able to use them. In fact, he's moving so he's left me his stuff.

1000w Dual Arc bulb (600 hps/400 mh)
1000w Digital Ballast (Switchable)
among a few other things

Anyway, he mentioned that digital ballasts need a specific type of bulb. Do you know if this is true? Can I run the Dual Arc or do I need a special type of ballast for that? Some help here please....
