How well do the Kaidomain/DX Kennan type (AX2002 IC) drivers hold their current levels?
I have a MTb light setup in the making that I have been testing.
With 2x 18650 cells in series feeding these drivers & 2x Cree R2's I get these results.

Started at 1000ma
After 30 minutes 900ma
After 1 hour 800ma
After 1 1/2 hours 710ma
After 2 hours 660ma

Is this normal or should the current levels stay where it started?.
