Battery lamp yes - suitable for bikes No

Due to some positive reviews I bought this as a designated bicycle lights Battery lamp. At first glance, a fairly solid lamp with quick-release handlebar bracket. This closure makes but its problems. Preloaded overtighten, you can no longer tilt the lever (unless you want to risk a breach of plastic). Preloaded Although too little holds the lamp but only until the next pothole. Then decreases with time and has a bottom floor lighting. Intermediates do not exist here. Either a full revolution or unlucky.

The illuminance is, as indicated in the heading, quite useful for use as a flashlight, for road purposes on bike unsuitable. A small circle with 1m diameter front of the wheel is seen only in complete darkness. Otherwise you will look but also nothing but darkness. Reflective road signs or even the illumination of the entire roadway width are unthinkable here. When driving at dusk, you do not see the light cone partially. Only the two-way traffic "could" pay attention to one of the light emitted. Had me there but not so sure.

If you do not buy the lamp for the bike, it is quite usable for power outages or similar. Therefore, two points.
