I believe there are some important differences between a well-known manufacturer and its expensive stuff, and a newcomer offering the cheap one with spectacular technical data.
I have several Petzels, the oldes one almost 40yrs old and still working, all my headlamps get stuffed into the pack and pulled out again numerous times and they never had any defect. They just work as expected.
Once a Petzel broke, and I got a free replacement although the purchase was 9yrs back.
