Yeaaahhhhhh!!!! -- Thanks a million! Great photos, great review/comparison!
Technical notes:
Maybe your Tank specimen doesnt perform as nicely as mine. I did intensive and extensive tests and measurements and documented them in 2 threads (the review, the comparison review incl video). The Tank has sort of a "constant current" driver and therefore there is no perceivable downstep/drop in brightness (as shown in my video). With an Eneloop the current *never* exceeds the 1.8A mark and typically it's constant between 1.6-1.8A which is a good regulation imho, here a quote from my review:
Hopefully my V3 sample is as nice as my other copies.. yep, there is some lottery involved with the hotspot beauty due to the tininess of the reflector and its manufacturing tolerances.
EDIT: my above quote actually indicates that the light has regulation which is better than constant current regulation. With an overcharged Eneloop cell (1.55V resting voltage) amperage is 1.6A@Hi and with an almost depleted Eneloop cell (1.28V resting voltage) amperage is 1.8A@Hi. And in between, most of the time (~1.4V), amperage is 1.7A@Hi.
