I have a 4x65 CF fixture ( its at the LFS but I believe it was a Corallife or Odyssey ) and one of the ballasts went so I can only use 2 bulbs and the moonlight. I use this on my planted FW tank so I would prefer to be able to use all four bulbs. I have no electrical experience. Anyone here in LI experienced in this department and want to give it a shot ?
