OK, it lives. Ignore the sick corals in the tank (it has been bit of a hospital tank for things that I'm trying to revive - apart from the morphs, they love it in there and grow well! Just closed up at the moment as I literally snuck into work at the break of dawn to get this all done before anyone saw me and started asking me work questions....)
Can control mitral individual channels and also an overall power percentage, overall percent doesn't seem to go lower than 10%, so have had to keep the individual channel levels fairly low to not melt the glass on the tank!
Should do pretty well on there I think, replacing a DIY 4-led setup that had about half an inch of salt creep trying to kill it :D
