I just made board for 2 luxeon REBEL lights using NUD4001 driver. I used 2 NUD4001, connect them parallel and use 2 Ohm 1/4W set resistor what should give 0.350A per each, as they are parallel, current of 0.700A should go through both REBELS ( they are conneterd in row). But when I measure current it shows about 0.17 A, I made second one and it shows the same current. It must be some stupid mistake that I just can't see.
