always a bright spot

(Almost) all here, never to stand in the dark.
The flashlight is super bright - naturally bundled as far-reaching as both spot floodlight, even more so.
Since the lamp with both the supplied LiIon batteries (3.7V / 1600 mAh) as well as alkaline batteries (1.5 V), and even with NiMH batteries (1.2V) - then somewhat fainter - works , is not a premature interruption in partially discharged batteries to be expected (as with other inexpensive lamps with built LiIon batteries often found).
However, with low charge of course the risk of damaging the batteries (single cells are likely to have no built-in protection circuit, as with equipment batteries usual).
By always hot standby battery (without Selbstentladubg) you can be certain not to stand on the way back in the dark even during long night walks. Just a pity that comes with the charger no adapter for European sockets.
