Project requires 2 XM-L leds, one 2700K the other 6000K . each with it's own 3A driver. The drivers ( DC bucks 8-18V DC 3A rated )have provisions for a rotary potentiometer for dimming ( 50K pot) via 2 solder holes on the driver. I have access to many different pots if needed including dual gang, triple gang, linear and log or audio taper ones. My goal is once I set the color temperature with ONE pot (most likely ganged to both leds for the "mix"), I must have another pot for the overall dimming of the mixed in color. I need the lamp to have only 2 pots, one for color setting and one for dimming. I imagine using 2 dual gang 100K linear pots, one connected to both drivers and the other pot connected to this pot in a parallel config. Is this the only was possible. ?
