I am selling a used Giesemann light I bought in December 2008 from someone on ReefCentral. I used it till Feb when I bought some T5 lighting. The previous owner said he used the bulb for 5 months. I would like to sell it for $180. I bought it for ($260) I can deliver in the Oakland/SF area... otherwise please pickup in Oakland. One thing the seller did not tell me was that the fixture itself makes a buzzing noise. The ballast makes a little noise at start up but I think its quiet afterward. Below is a picture of the item for sale.
