I built a similar little light using 3070 4K's and cree 660's. I ran them all off an hlg700ma. It was a test build so I didn't put much into it. But a way I thought that might work to have red on/off control at least was to use a switch to bypass the reds straight to the next COB. And the other position would be running though the reds just like oyu have it in post #15. It would only allow on/off, but would be better than no control, and would give simple electronics and lower cost. I am just not sure if there would be a problem for the driver to run a switch like that while the sting is on.Right, each star drops about 10V @ 500mA. (The four internal diodes are connected in series.)
I was thinking about asking on the forums if the LED Engin stars were any good but these are new and improved so I'm in. ;)
I'll ask around some other places
