So I'm slow with posting but here are two pictures of my tank running the LPS/SPS+ setting at 80%. The light is mounted 11" over the water line and coverage isn't bad. My tank is 48x24x21 tall. I have my custom Orphek 36" bar running in the second photo which gives just that extra blue punch and gives a little more light in the front.
My biggest complaint with coverage are the left and right sides. I could probably raise the light another inch or two and increase intensity to take care of that.
