I am currently in the process of fiddling with this flashlight, just waiting for this new nanjg 105c from intl-outdoor with 3.04A to arrive, will also insert a copper slug under the emitter. Together with that driver I ordered XM-L2 T6 so I could try out that combination also!
In this moment I have regular/old Nanjg 105c (2.8A) installed and I can feel a heat of the light beam when in HIGH mode
