Strength and stamina with small criticisms

Basically, the lamp is good. I operate almost exclusively in "sleep mode" while jogging in the dark, because the lamp already brings a lot of light on the road. A few little things bother me but slightly.

Positives:
- Long burn time
- Far-reaching beam
- In spite of the weight still conveniently portable

Negatives:
- There is no diverging lens - though not tragic but Schade
- The weight though still comfortably already noticeable and it requires relatively tight belts to tighten. On the detachable upper band can not do without thereby
