It's a Kessil A360, there isn't much I could find, their website is geared to selling not DIY.
Edit: Just to add more as per Wawa, the light is a Kessil A360, it has two 3.5mm(headphone) jacks, both use a 0-10v signal, one to control intensity, and the other to control color, at the moment I am only concerned with the intensity, I just want to turn it on and off with a dimming effect. In the future I would like to add the feature to turn it off when the sun is out (LDR?), I face north-west and so only get about an hour or two of sun right now.
