Workhorse 7 is a ballast you see for sale.  It can run upto four bulbs I think that are t5Ho, PC or VHO.
To overdrive all you do is attach all four leads to one bulb(thing its the yellow wire).  I tested it by first doing one, then adding another and another and so on.  Just to see what the difference is.  I have not notice any more heat then normal.
