I rate this lamp, even though I do not possess. Priced 50-70, - you get a sophisticated lamp that comes dibasic. Equipping with 4x AAA batteries promise a relatively long operating life with average Use. But what is under intensive use at full brightness. Because that's really the money. A battery variant is better off off. The light output is rather average, only focusing on the range is somewhat better. The specified Sensing wide is something for theoreticians and yet very optimistic. I own a NiteCore P16 in similar price range. They can be operated with R123 batteries and with 18650 batteries. The light falls from comparison devastating. This is as if you accelerate a car once with and once without the attached trailer. The often criticized lack of Waterproof LED is what kind of people that probably do not want to give the lamp from his hand to take a shower. My brother is after this light compared not so in love with LED Lenser. Conclusion: Without wanting to speak ill Led Lenser, there are hard-earned for the money better and more innovative lamps, the price does not have to be expensive. You just have to look a little more closely!
