You need more amps. I don't know what sort of power that LED driver board puts out, but I bet it's not 10W. The proper way to drive that LED is with three independent current limiting circuits, such as Buckpucks or similar, and the batteries need to be able to handle the total current draw from all three channels, otherwise the red channel will pull the whole thing down. A quick fix might be to slap a current limiting resistor on the red channel, but it's not an elegant solution.
You don't have enough current, that's why the button brightness changes with different blade colors. The red channel in the LedEngin is a heavy draw, as is the red LED in the button. Red will always hog current from the green and blue channels if you're low on amps. The blue and green channels on the LedEngin are pulling it down too, but not as much.
Thanks! Any suggestions on how to fix it? I suppose an 8-position rotary switch, with each line (position) having its own dedicated resistance set-up, would work better, but I wanted to keep it simple...
