Very good illumination in the short and long range (150m beam range). In Turbo mode (750 ch) suitable even for technically challenging trails. On the lowest setting (100 ch) still ok on the road. I have to say that I now use only as a helmet lamp. On the handlebars I constantly had the feeling I have to adjust the height. Am not helmet, I therefore like better than helmet lamp. For me a top MTB lamp!
