NO is the short answer becasue if your just multi wiring the ballast there is no sure way to tell how much power the ballast will send where, you could get 400 to 2 off them and 100 each to the others blowing the 2 bulbs and even your ballast, not worth the risk in my opinion. if you ballast was designed to run four 250 watt lights it would have a switch to let you..
