After much back and forth I decided to rather expensive headlamp of Two Brothers. Initially, various negative recessions have deterred me, surprises again the Focus liese set difficult or battery compartment make problems. Fortunately my local electrical store the lamp was available and a short "groped" brought me to the conclusion: Fits. I use the lamp mainly for fishing or running or biking, and I just can not find a negative point. Even the high price is absolutely reasonable in my eyes. The light output is excellent, the battery life is impressive and absolutely Focus is set perfectly and adaptable for any application (just like the brightness).
