Really ??? Lux is not a measure of brightness ??
And Ive posted the results for the Batt's , what it all equal's is a direct comparison , if you dont understand that , then reading this is a waste of time .
This thread is getting ?? a little out there , so Im going to stop replying now . Im sorry , but ?? :tired:
Lux is only a measure of hotspot intensity -- how well the light can throw. A highly focused 10 lumen light can absolutely smash a 1000 lumen floody light in "lux".
But as stated, try using 2x16340 cells. Most modules are not regulated on 1x18650, and fall into direct drive. You are then victim to things like forward voltage, individual circuit impedance, etc.
