Robus, water (sealed) IPx8, Excellent elected Leuchtstärkestufung (quite dark for reading in the tent; for running light and super bright);
The lamp is easy and does not slide. Operation with two different types of batteries (with little modification) provides a lot of flexibility.
What I miss is a little red light; Unfortunately, there are no known to me headlamp with a neat bright red light (I had one of Petzl with red filter)
