I thought about trying to do something similar, but mine are daisy chained to my Apex Controller, which prevents them from being controlled independently. The Apex can control color and intensity, but those settings apply to all the lights at once. Also, because they are daisy chained, I can't turn on one Kessil unless the one before it in the chain is already on. This means that I can have the one connected directly to the Apex on by itself, I can have just that one and the one next to it on, or I can have all three on. No other combinations are possible. I can't have just the middle one on for instance.
I don't have any experience with the Kessil Spectral controller, so I don't know if more complex programs are possible with it.
