If you're like me radiators for the bike and a LED on a key chain already have a Maglite for the basement NEN, why you should buy anyway an "Emergency lamp" ?! Simply, this lamp is very small, about the size of a thick clock, the battery life is 70 h (economy mode) indicated what I already remarkable find for two button cells, the various light functions (eco, white, flashing white, flashing red, red) are always helpful. The rolling end cord can also new possibilities to how replacing the bicycle lamp, lighting the Handober- or sub-surface when it is worn like a clock (to whatever, maybe read terrain maps, find ashtrays, rumschrauben in the corner of a car) or at Campen his plate in his face to light, because by a ball joint, rotation is possible in all directions. Made this lamp is the way in Malaysia, but by the 10-year warranty in Germany we are definitely on the safe side. The product is made of high quality plastic, nothing wobbles, switch goes sometimes cumbersome, but makes the impression of robust until securely locked (so if, then on; if, then it remains off). Light duration / intensity: up to 70 hours in Eco-mode, 55 hours in full power mode, 30 hours LED red light (whether flashing or permanent lighting). But why three white LEDs up to 70 hours, a small red LED creates only a maximum of 30 hours, I do not know. In any case, these red lights may well be used with the tent, as there is a very pleasant lighting for the other (while asleep) creates. Finally, the three white LEDs are sufficiently strong (25 lumens max.), Although it does not light up all the way out (rather Punktfokussierend), but 3 feet in front of the feet in the night walk are loose inside. So I'll find a thousand other options for my little Petzl. When the review was helpful Yes click. Many Thanks Steve
