600w MH conversion in a Lumatek lk600

does any one no if a 600w MH conversion bulb will operate smoothly in my lumatek dimmable lk600 ballast? (thought conversion bulbs were designed for mag ballasts)

or should i just get a regular 400w MH and adjust the wattage on my ballast? Was leaning toward the 600w conversion for lumen output but was questioning the operation of it in my digital ballast.
