What frustates me is, as of yet, no one has been able to say what the lumen output is on Liion with any AA Zebralight, nor if the output on H1 is regulated, as it is with Eneloop, or if it steps down, etc. There are more than just a few running Liion in their ZL, and yet reports are nothing more than, "omg it workz! LOLZ," and "it's brighter." I'll leave my SC5c on all night long with an Eneloop during consecutive nights for weeks at a time. Sometimes I discover the next evening I forgot about it running, and just leave it on for another night without touching it. Any Liion users doing that? No one knows, but I suspect none leave it running on Liion for more than a few minutes.
Also, apparently it is just me and no one else, but what I have discovered is that the deeper into the night it is and the darker it is, the less light is needed. By midnight, anything more than 25 lumens is painful unless I need to illumniate an entire room, in which case 140Lm or so is more than enough. Thus, unless S&R, which no one would use an AA ZL for, the brightest lights, 1200+Lm, are most useful during the day, or just after sundown when there is still plenty of ambient light from the sky, for killing shadows when dark adaptation is nonexistant. Who is blasting 700Lm inside their home in the middle of the night, and why?
