I bought the universal bracket to my LED LENSER L7 to fix the bike. It should be noted that the flashlights by LED LENSER have not street legal, and they are therefore not likely to use the bicycle. This bracket is indeed sold as a universal holder, but its use as a bike mount seems to me the most sense, and I'm going to use it further. I personally have an approved Dynamo lighting on the bicycle and the LED LENSER use then as a "high beam" on roads where no one seems to me contrary to what I could hide. The only light at the bike but I would definitely not use such a lamp, I only need extra light, I am often in the evening and at night on country roads and country lanes the road and there you will be very glad if you have additional lighting. While it is not officially permitted, but even during a routine check by the police, I got no problem with additional lighting. To support herself, she is very robust, taking care of my three different bikes and sitting everywhere bombproof. There are included 2 different allen key, these are for different handlebar diameters. You can see the light at the top fix this easily disassemble when needed, what would I do even if I my bike somewhere out abstelle, since one could otherwise easily steal the lamp. A rubber band to fix is attending, but also holds without. Strong buy recommendation.
