Well I don't know how hands on you are or experienced with ballasts but if it has one power cord and 2 lamp outputs then you could open it up and just remove the Common and 120v for just one of the ballasts. I actually just did this to my dual 400 I made a wile back to use only 1 400 in my veg room. If you remove both power input wires from the incomming power you can leave the lamp still wired up because the 2ed ballast wont be turning on and not trying to start a bulb.
