Also why the 4 15's? Why not 2 30's? Thanks
And I think it's a little better in case the light ever fails. Redundancy in a reef never hurtsusing multiple XR15's allows you to spread the pucks and have a more even blanket of light. If you had a deeper tank then i would suggest XR30 but for the average tank i see XR15's as the way to go! I love mine
