Welcome to OG @skyeden , you’ll enjoy it here, lots of helpful info/people, etc. !
I would return your light and get a bar-style fixture - 240 ish watts would work fine for your 3 by 3 tent. 
.
I’m not sure if SF has any bar style lights but there’s some really good lights that are probably better than the Quantum Board style lights.?!
( Imo.).
Good luck with whatever you choose. 
.
Happy growing.
Gaz.
