At the end of the lamp is the push button for switching on and off. You have three options what type of light you want to have. Mode 1 is a really bright and clear light, mode 2 is dimmed noticeably, so as not to dazzle oncoming persons or vehicles, but still light enough to himself to have good vision and mode 3 is a flashing light with a very high flash frequency, with which you can make very good attention.
At the front part of the lamp there is also a ring with which you can still adjust continuously the focus of the lamp. It is thus possible either to illuminate larger areas or to adjust the focus so sharp that you can see things at close range even in absolute darkness optimally. Whether the promised brightness of 500 lumens is achieved, I as a technology primacy can not judge, but my experience from daily practice proves to me that the lamp is easy for all my needs in daily life and easily bright enough.
In addition, a holder for the bike is still included what more versatile and practical makes the lamp, of course. Very practical is the hand strap of the lamp that you can put around your wrist beautifully. The lamp fits comfortably in your hand and makes use of a processing perspective, a very solid and robust impression that they probably can quite put away the odd shock easily. This will show the experience involuntarily over time ... :-)
Thus, this flashlight meets all relevant requirements for me. It is handy, practical, versatile and makes a stable impression. Longevity I can not assess at this time. Therefore from me 5 stars, I'm very satisfied so far.
