This flashlight weighs next to nothing (in the reasons only the weight of the two batteries) and emits incredibly bright and wide, I am very satisfied. However, I found the process in detail is not so special. According to the manual, you can unscrew the lens to use the lamp as a parking light, thereby instantly seal rubber has with me, however, solved. The lamp now sits quite loosely on the shaft and goes easily from even if you have them even turned up. For the price but still a great performance.
