I ordered the identical metallic lamp on Ebay (25 Euro, incl. All) and also get out of China. In addition I have Ultratfire 4500 mAh battery (just over 1 euro each) and 2 Trustfire bought 2 (vemutlich gefäschte) 3000 mAh battery (just over 4 euros per piece). The specified number of lumens, I can not verify, but it is by far the brightest light, which I had previously. The water resistance is given and the operation without problems under water. However, I have used the lamp without gloves. Then adjust the brightness by sliding Regeler succeeds quite well. However, the extent to succeed even when wearing gloves, I can not say. In fact, the beam is sufficiently large and in the middle is the brightness is greatest. The light color is certainly easy in the cold / blue area, goes for me but overall still as quite natural by. The slide switch can not be determined (from). During transport, the batteries should be removed but anyway, because if accidentally turned on, the lamp may be very hot. About the short sliding path 25 brightness levels can be switched so that the setting is very fine and is almost infinitely.
The term of the Trust Fire 3000 mAh battery is with me 65 minutes at max. Brightness with the apparently fake 4500 battery captures the lamp after approximately 15 minutes to flicker and then go out completely.
Over water the lamp is only partially usable. At full brightness it gets too hot within 5-10 minutes for normal use. So here only a short-term use or gerigere brightness is possible.
Overall, a great (mainly underwater) flashlight at a very reasonable price for performance.
