I just ordered:

a pair of Iwaski 6500K 400Watt bulbs

and

4, 7100K (460nm) 65Watt PC bulbs


what ballasts should I run these off of? As I understand it, the MH "should" be run off a Mercury Vapor ballasts (right?), but what about the Power Compacts? I'm trying to stay away from the "IceCap" kind of/big $$$ ballasts and trying to stay with the DIY kind of ballasts.

Part numbers help.....

thanks guys
