Okay i just got the the mlc 8 at. Im currently runnin 5k on 120v and i want to change that to 240v.Im using xtrasun 1000w dual voltage ballast. so shouldnt it be as easy as movin the power chord from the 120v input to the 240v and action? or what am I missin? the mlc has regular 120v outlets so everthing is matchin up,but the lights aren't comin on.Do I need to rewire the ballast? I thought on these kind u dont have to . But im not sure.
