Very good front

As always with Petzl, a very good front. This new adaptive techno is a rich idea and very useful in the dark. Only small problem underground, but that is not strictly speaking related to the product, is the reflection on the water vapor that is released into wetlands, and which reduce the light volume when the lamp comes to illuminating this white steam. Being caving and underground explorer, it is a problem that we bypasses exhaling on the side :), but if steam comes out of your body, nothing to do but walk / climb unabated.
