I have a 4 ft Giesemann Infiniti fixture for sale. I bought it at Bulk Reef Supply about 2 1/2 years ago. Its in great shape as seen in the pictures. It has (2) selectable Luxcore Ballasts that are like new. This fixture cost me $1,500 new. Its a steal at this price. Here is the description of the light and ballasts included. I also have a link to the fixture where I bought it for reference. I can get you a shipping quote. Depending on where you live its probably going to range from $60-$100. The current bulbs have approximately 5-6 months on them but I do have a brand new set never used I paid $200 for with Halides and T5's I'd throw in for $100.
