Question about lighting for a 40b coral only tank

[AUfishguy]

So I just got a drilled 40 breeder and I plan to use it as a coral tank only. Mostly SPS and some lps. I found this light an evergrow it2040 on craigslist new in box for $200 but its dimensions are only 15.7 inches x 8.2 inches x 2.5inches. Is this big enough for the 40 or do I need something closer to the length of the tank. Also any recs on lighting is appreciated. I linked the light below

Na, you'll be ok with that light, get it up a bit off the tank and it will spread nicely.
