I've got two 48" flourescent single bulb fixtures with built in ballasts. They sell new at LFS and petsmarts for $89.99. I am willing to sell them for $60 each or $100 for both. They both will include brand new bulbs never used, as i swapped them with coralifes as soon as i opened them. They are about 4 months old, only used for two of those. I upgraded to MH.
