I think my emitter is an V4 3D, I did this a while back. Fairly certain that’s the lumens difference. My charger takes the IMR cells to 4.21V, that might be the current difference or simply the clamp meter with big heavy wire. Don’t know. There’s always going to be variables, like a thermometer. If you set up 5 thermometers around your place, it’d be unlikely 2 of em read exactly the same. The lights are like that, varying with time, age and temperature. For me, my numbers… your numbers… djozz’s numbers… Richard’s numbers… just a basis to go by, I doubt there’s hard cold facts anywhere to be found when it comes right down to it.
My light box uses a .345 conversion factor.
For amperage, I use a 12ga Turnigy loop with a Mastech Clamp Meter. (run the single 12ga lead from ground to battery, clamp the meter on the loop that forms)
I haven’t ever used the 20K resistor, the blink doesn’t bother me in the least.
I was merely trying to show what we might expect from the little K6 with one of these top 14500’s. I believe the K6 will have an TIR optic, so everything will be different on the output and beam profiles.
