I m going to post in just 1 tread, but my view goes for all the Zweibrueder / Led-Lenser lights:
THEY JUST SUCK !!!
much too expensive for the value, no HA, not watertight, and finally these damn optics with the hole in the middle. The older models were a real PITA in this dept.,
the model shown above still has this recession where dust and whatever will collect, there is no front glass to save the optics from scratches, ... (at least I never saw a model with one).
Junst handled some davids in their original package and think there is no glass either, way more expensive than Fenix ordered from overseas, ...
Then there are these runtime claims only a dd light might achieve with almost no output at all, ...
In their seize dept: get a comparable Fenix!
