I have often had with the lamp during the dark winter months, because I run routes, which partly come along without lanterns. I was pleasantly surprised by the brightness, although I do not consider the darker of the two settings to be sufficient. Positive: - Surprisingly light and sufficient even at a higher movement speed (eg in complete darkness in the forest is the lamp presumably not be bright enough to work, but for a walk) - Very light, so it sits very pleasant and does not slip - Long battery life (manufacturer says: 40h at full brightness, 80h at half, I had to change no batteries) - Price / performance almost unbeatable Negatives: - Could still be a bit brighter even though I usually consider it to be sufficient
