First point:
The mr11 and mr16 are not swapable bulbs. The Fluval Edge comes with sockets for MR11, you have to swap out the sockets for mr16. You can use the same power supply.

Second point:

The led lights that are sold in Lowes are not reef appropriate lighting. They are too low on the Kelvin rating and will give you a yellow light. Look here LED Wholesalers.

Third point:

You have to figure out a way to protect the LED bulbs.
Otherwise this will happen if you leave them exposed to the saltwater:

A piece of acrylic to cover the opening should be enough. I used a piece of scrap I had laying around.
