Can someone measure the current at the tail of their Quark aa? Does 800mA on a 14500 and 1.2A on an eneloop sound right?
No it has to boost the 1.2v+ of a NiMH up to the vf of the LED ≈3v+.
So if you're measuring at the tailcap, you'll get what the driver is pulling out of the battery, which will probably be about three times as much as the emitter is seeing.
If you measure it at the emitter, you'll get the actual amperage to the emitter, but that could be problematic.
