So I picked up a used 6x36 dimmable sunpower t5 unit about a month ago. Unfortunately is definitely to long for my 30x30 tank and spill light everywhere. It also came with 6 brand new red sea spec 15k t5 still in package. I would like to trade the unit and bulbs for a 8x24w ati unit, doesn't have to be dimmable, just by ati, I'm in freehold. I will post some pics shortly when I get home.
