The light spread is about 24 inches x 12 at 5 inches above the water with the 90 degree optics. I'm also more like 15% white 30% blue now that I'm home looking at it. The spread increases some when I turn it up, but I'd like to get my corals use to the increased lighting. I had intended on mounting the light 2-3 inches higher, but I apparently measured poorly when rushing to get it up before work. So something I intend on fixing during the week. I would also like to try removing the optics since its a small talk, and I'd rather have more spread than I need depth since I only have about 11 inches of water to the sand bed.
Over all still very very happy, just a few changes that I need to make on my part.
