I have a 36" black 4x39 Watt TEK T5 fixture with Giesmann bulbs. There are two switches, and each one controls two bulbs. It is in very good condition. I have been using two of them over a 125 planted tank. I have replaced one with an LED fixture and will do the same with the second TEK later this year. It is $100, but if you want to buy both fixtures, you can have them for $180. I can deliver it to the Catfish Convention; if you want both, you may have to wait as I would have to order the LED replacement for the second one.
