I assume that dentillozie was asking about the deal thread, but I could be wrong. M4D M4X´s deals
If you only get 3.1A in DD it’s because you have weak cells or high resistance in the light. Probably weak cells IMO. The light with the stock buck driver still in place fares worse because the losses in the buck circuit are too high to even begin to regulate at such a low voltage (again, due to weak cells and/or resistive losses).
