Dear Jason and Jeremy we have a problem. I had a 3 week old aqualine bulb and I traded with a fellow reefer in RC. I recieved the bulb yesterday I burned it for to 2hr, It worked fine. I came home today and noticed that It wasn't burning. Im in desperate help!!! I am without lights on my tank. The guy I traded with sent me his bulb first. I shiped out his bulb today. He said he bought it from premium Aquatics a month ago and only used it around 40hrs. Please If you could, replace my bulb and send it next day priority. The bulb I have now is a coralvue 15k 175watts SE. Thank you Tony
