Wondering if the AI Prime is right for my tank


Reefing newb
My LFS let me borrow an open box Current USA Orbit Marine Pro light he had and told me to keep it for a day or two and see if I liked it. He said if I didn't like it he'd recommend an AI Prime for my tank.

Do you guys think the AI Prime would be suitable for a 29g 16" tall tank with a few softies and SPS? It says the spread is 18" which would leave approx 6" on either side of the tank unsuitable for corals.
