The lamp is sold as a bicycle lamp without a license, that was okay for me. The light is very bright and the biggest effect is probably the most that you can dazzle motorists and pedestrians so. The light level or the illumination is for cycling the light level is not suitable. I like it better when the road is illuminated wider and slightly downwards. When the lamp is however so that a circle of light flashes and the lighting is more reminiscent of emergency or at best as an additive light.
To process and form is to say: It creaks almost nothing and the processing is okay so far except for a few small things in the lamp: A fast focusing is not possible because it occurs on a bike as if you would have infinitely long from one end position turn in the other end position. In addition, I find it disturbing that you do not feel the end positions correctly but seems somewhat blurred. They are not obvious signal: Here is the end! But: "That's it!" But in a language that you want to rotate further as yet turn to look at whether there is not something else going. Unfortunately, the focus sharpens something. A star deduction. The handlebar bracket for lamp acts alone somewhat clunky! Although the Bewegungsgrat is simple: To use the lamp in the inclination adjustable by mounting on the handlebar but unfortunately did not turn !!! Still a deduction.
As a reflector, a plane-convex lens, this gives the lamp from a distance a beautiful, almost high-quality optics, since it is strongly reminiscent of a Xenon headlights on the car. When viewed macroscopically (would say yes but the admiration was then) was seen in the wreath in the inner workings of jagged edges and the silver plate to the LED around also revealed irregularities in the cut and in the surface. For the lighting operation not disturbing but the high quality of workmanship I question and say it is not great but okay for the price!
I give the lamp 2/5 points because it impressed me technically how much light from a semiconductor quasi comes but everything around it is much better and I would of a bicycle lamp definitely expect (on the light level is it to). For cycling, it is in my opinion inappropriate and therefore goes back to Amazon. Perhaps we should be in the description: as a flashlight for the tool case suitable with moderate use, and if necessary even as emergency bicycle. Where for the holder is likely to be too large.
Oh yes: The rear light is right, which is also like it very much!
Thank you for reading!
