After doing some research, it seemed as if the Aquailluminations Sol units had many of the features I wanted. Independently controllable white and blue channels, enough power so that two units would allow me to grow stony corals in my 90 gallon tank, a price tag less than the equally intriguing Radions, and finally, the ability to interface with my Reefkeeper Elite controller.
One issue was in mounting. The ceiling wire mouting brackets that come as an option with the AI Sol lights allow for mounting across the width of my tank, not down the long axis. I saw one person on YouTube mount them down the long axis of the tank on a single mounting rail, but I saw two problems with this. First, the lights balance on a single rail so the smallest amount of weight, say from a power or data cord, would tilt the light away from an an angle normal to the water's surface. Second, a single suspension bar running down the length of the fixture blocks the cooling fan which is centered on the AI Sol module.
The assembly and mounting are shown in the video.
