led question

That fixture is 13 watts. That is like 4 of the Cree most people are using for the DIY jobs. 4 Cree might be a little light limited for that size tank (what is in it, what are the dimensions). Those are probably less efficient than Cree so it probably cost more to run than Cree for the same amount of light.

Personally, I would keep looking.
