After doing a lot of research and reading I decided to go down the LED road.
I did not want to compromise my existing setup in case I wanted to revert back to T5, so I decided to go with a pair of Hydra HD 26's.

These bad boys fit perfectly into the existing T5 cavity without having to remove anything. There is enough room for air to flow over the top of them by the existing T5 cooling fans. If used at 50% then the existing fans can be turned off. The best part is I can design my own lighting spectrum and control it from my iPhone with the Hydra app.

So far all my corals seem to be happy.
