*From 500 mA to 900 mA, full dimming range ( 2 % - 100 %) and wide CCT dynamic range available in the whole area.
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, but the dynamic range may be limited. Each single channel can dim
down to 0.5 mA level.
