I spent some time messing with the placement of the Kessils over the tank today. I downloaded a simple LUX app on the cell phone and took some measurements. With the Kessil on the lowest setting, it produced 6000-6100 LUX at approximately 4.5" below the light. The SBReef 16" basic boxes produced 5700-5900 LUX at approximately 8.5" below the light (about as close as I could make them). The coverage of the Kessil really caught me by surprise. After reading a lot of threads I had some concerns about their realistic coverage until I watched
BRS TV Episode 21. After mocking them up over the tank, I was blown away by the coverage, shimmer, and color (set at approximately 70%). The anemone is roughly two inches right of center in the tank.

Kessil A360WE 5" above water line (right side SBReef on). The Kessil is mounted 8.5" left of center.

With the placement worked out, I got to work on getting the canopy ready for the lights. Had to run over to the hardware store to get a hole saw (4 1/8"); those suckers get exponentially more expensive after about 2 1/2"!
The holes came out exceptionally clean! I had absolutely no splintering, not sure how I pulled that off (pretty sure it was because of the Red Gard and paint on the underside).
Still brain storming how I want to mount them within the canopy. I have a few ideas but I havent settle on one yet (I'm sure I'll wake in the middle of the night with something).
