I've got a slightly used T5 from a Red Sea Max 500, full of all 10 bulbs. 540 watts total, 7 bulbs are Aquamedic Reef Blue, 2 bulbs are Red Sea 22,000 K
Actinic, and one bulb is a Red Sea 15,000 K
. Though I'd like to use it, I'm already satisfied with the light I'm running. Everything works, the bulbs are relatively new, and other than a couple small scratches, the fixture is in pristine condition. The only obstacle you may encounter would be mounting this beast on a tank that isn't a Red Sea, though it can be done with some DIY ingenuity.
I have no clue what this fixture is worth since they aren't sold without tanks, or at all anymore. I would attach pictures, but I've hit my image limit. For more info or pictures, PM me!
