A very good lamp camping and hiking. Immaginez already used batteries with 70% still see it very well. At full power, it can reach up to 300 lumens which is very appreciable lorqu'on seeks to set up a tent in disaster when the sun has already set. The only drawback may be its weight (almost 1 kg with batteries) especially for those who have to take him on a hike. So remember, it takes 3 LR20 batteries to power but when you weigh the pros and cons, you quickly realize that this is just a detail and that this lamp is the ideal companion for nights under the stars .
