 They should indeed run both kinds.  The only thing that I'd be cautious of is that the specs say something about a "BTL" (ballast to lamp) wire distance of 5'.  I understand people have cords longer than 5' so I guess you can stretch that requirement out a little.  I don't have the ballasts myself so I haven't had a chance to investigate what the practical limits are.  If you go the DIY route let me know if you find anything out, I'd like to know more this myself.
