Brian, I don't think you can go wrong with that decision I ran 6 T5s for the first year and had great results. But, when I upgraded my tank I had a decision to make that really boiled down to what I could make work for the budget I had available. Turned out that through a group buy I was able to go with LED. While I don't have months of data to back me up, I can honestly say I am very happy with them.
