FWIW, I loaded up mine with 3 AA in plastic adapters, NiMH non-LSD which all tested around 2100 mAh. On high, the light ran plenty bright for a couple hours then dimmed to a still bright indoor-range light or a usable outdoor light for maybe 8 hours, then still did a usable dim light for another 24 hours. By usable dim, could probably navigate indoors in the dark and read up close.
However, one of the lights does have a fiddly button, and the zoom sliding mechanism is nicely tighter than the other one which is just okay. Still like em a lot though, especially after the battery test.
Reckon I'll buy another set and swap out parts until I get tight zoom slider and good buttons.
