I'm not a lighting expert by any means, but that light doesn't look like it will do anything useful for a reef tank of any size. They look like they are more for artificial tanks.
the RGB colors are probably going to be useless for anything and aren't going to provide the spectrum of sunlight. All you need are the 10k whites and blue actinics.

There are a couple very simple setups that screw into a standard light socket, so you could get one of those and a cheap pendant light fixture to do what you need
