The technical data of forrader C12 are from my point of view (pure users, no flashlights Freak) identical to its predecessor, C8, only the front third of the lamp is now more voluminous
This allows the lamp a little grip handle and the weight is better balanced.
The C12 also acts 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.
This type of battery is still quite rare in Germany and not cheap. Keep this in mind so please before buying.
In addition, the 18650 battery should necessarily be protected against short circuit and overvoltage.
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.
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 change by a slight pressure or a normal double in the next mode.
The next time the lamp noted practically the last mode
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!
SOS mode I find very useful.
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 :-)
So I can 100% recommend this lamp.
The term is enormous, I can now burn test, two hours, and the light output is further 100%.
I hope this review could assist you in your buying decision ...
