1) From 500 mA to 1200 mA, full dimming range ( 2 % - 100 %) and wide CCT dynamic range available in the whole
area. Each single channel can dim down to 0.1 % level.
2) From 100 mA to 500 mA, the absolute minimum dimming level is limited to 10 mA of total current. Dimming / CCT
control possible all the way down to that current (dimming range 10 % - 100 % at 100 mA), but the dynamic range may
be limited. Each single channel can dim down to 0.5 mA level.
