Had the lamp already in some night courses in use. Here my +/-:
Positives: Intuitive light
+ In simple mode two levels 50% and 100% brightness (high mountain / downhill)
+ The distance-measuring sensor aligns the light intensity after addition of whether one looks into the distance, or on the floor
+ The ambient light sensor also determines the luminous intensity
+ Fits perfectly and is well adjusted, also caps, headbands etc.
+ Battery will last if necessary, a night, and it can also be replaced by normal AA batteries.
+ There is also a mode for a fixed light intensity without Sensorensteuerrung
+ Supernatant rain and also a Thunderstorm cloudburst problems
Negatives:
- The battery can only be charged via USB (USB Hub brings it to my little juice).
- While there is a lot of "light profile" which you can play through the software on the device for example. a profile
for Yourself, mountaineering, caving, trail running, etc. But could this not have any info, see what the different profiles, and how the light intensity should be handled in the individual stages. There's only try. When I profile but once stood with the trail running in the woods, I wished quickly the General two stages setting back because I can by the power consumption and brightness ago simply the best estimate.
All in all a super lamp. Even with the competition from their own home by Petzl Nao can keep up easily because they in my opinion still has its nose against the newer and lighter models in terms of battery life, robustness and luminous intensity forward.
