Light and strong flashlight, perfect for running in complete darkness in the forest or mountains. It’s worth practicing use beforehand, because the operating modes require reading the manual. Very light and comfortable, but the plastic feels rather cheap. It lacks that pleasant feeling of quality like the BlackDiamond Storm-R model. According to the manual, the flashlight works at 400 lumens for 2 hours and 40 minutes, but in reality, at -2°C, it lasted a maximum of 1.5 hours on a full charge. Since this situation happened twice, I assume this is the actual runtime at the highest mode, while the manufacturer claims a longer time in laboratory conditions. After turning it on again, the flashlight switches to medium mode. If you need more than 2 hours of light in difficult terrain, it’s worth considering a backup flashlight or a model with a bigger battery, like the Storm-R. Unfortunately, all flashlights over 400 lumens are no longer among the lightest. In summary – very good, but it has its limitations which you need to keep in mind.
