That in this price range not luminous miracle is to be expected, I think should be clear to everyone. The lamp offers but, in my opinion, for the cheap price (I have bought for 6.10 incl. Shipping) a quite ordinary light output even if they like some manufacturers always rhyme the values together is me far from the specified 300lm ( still a mystery) is likely to differ. In my estimation, should the LED light may make to the 50lm (For comparison, I have my Fenix LD20 used). The light cone is very easy to adjust with one hand. However, this is the spot mode (or whatever you want to call it, when the beam is small and light) ugly quadrangular and projected a slightly striped pattern which is probably due to the nature of the LED chip. (Is now described probably bad but its the basic message behind it is that one in this position the lamp head beautiful and especially homogeneous could make / to the illumination.) Concerning the nature of the aluminum case, I can not say all too much of durability after a week use. The paint may not seem to be all too resistant (already easy detachment for carrying in your pocket next to keys, etc.), but the function does not diminish and do not mind me personally. The housing on the other hand, seemed very thick-walled and robust. With water I would however caution because eg no gaskets on screw-head lamp are available. A little rain should survive the light in my estimation, but still. In the end I can only say that the lamp its price is definitely worth it and I would buy me back. So if you looking for a cheap flashlight with decent brightness in the price segment below 10, can find a compact, bright light that will certainly carry out regular services in occasional use.
PS. The star trigger, there was mainly because of the long lead time of about 2 weeks. PPS. At runtime, I can not say much unfortunately. The lamp is however noticeably warm in the operation and the first battery has verlohren already within a short time to properly tension, which is not exactly speaks for high efficiency. At least the brightness has nevertheless hardly changed noticeably!
