This "lights" meets these requirements perfectly. It was delivered in a nice tin box, with belt clip, a short chain with clip (which I will not use this because I fear that the chain is solved quickly, will instead use a small key ring), and a replacement seal.
4 light modes:
Low is very hazy, but it was enough to find the keyhole or look up on a map without completely ruining the night vision.
Medium is already light enough in order to run around.
High beeidruckt really happy for this size of lamp. Very bright and strong, how far it shines I have not yet tested.
The operation is very simple -> just turning the front unit necessary. Battery exchange is also very simple and the housing clutches his very valuable.
Unique buy recommendation. Will they give also my father.
