Almost brutally bright flashlight with 3 brightness levels and additional Strobo and SOS mode.

This flashlight acts directly unpack very high and stable.
The case is that makes the lamp light yet highly resistant from a black aluminum alloy.

The insertion of the 18650 battery (not included, as well as not charging for it) went smoothly.
The thread is very smooth and I did not have the impression that it is only built for some battery / battery change.
Since I already had other flashlights in use, which were threaded directly literally erased at the first turning. This is here so absolutely not the case.

Since no guidance supplied was available I had to try how to switch between the 5 modes (light / dark / Dimmer / Strobe / SOS). But just turn on the lamp with the push-button and then switch to the next mode by double-clicking. The next time the lamp remembers the last mode, which I find very convenient.

The luminous efficacy of the light mode is downright brutal.
I was able to light up more than 300 yards on a free field!
Under no circumstances should you look just a few seconds directly into this light, which will inevitably lead to serious eye problems.
This lamp is so absolutely not a toy!

Toll I think the SOS mode.
Since I came in hiking times in an emergency situation and we were not found until after dark is this topic for me much more relevant than before.
One can safely with the phone trying to draw attention to themselves.
This lamp is a good chance to rescue but certainly much higher :-)

Very positive is the battery performance.
After an hour test of continuous operation is no loss in the optical power detected.

So I can 100% recommend this lamp.

I hope this review could assist you in your buying decision ...
