Function:
The properly processed lamp fits comfortably in your hand and is designed also by design appealing. Adjustable are three levels of brightness: Bright, half light and stroboscope, which latter feature is hardly used in practice. Both ON / OFF as well as the different levels of brightness can be controlled via a pressure switch on the end cap of the lamp. You only have one hand free this can be a bit fiddly quickly. With the green adjustment allows the light angle infinitely adjustable. The specified up to 500 lumens will probably only achieved at maximum focus, so therefore have a relative value.
Brightness and range:
For me the two main aspects of a flashlight. And here I was, admittedly, pleasantly surprised. Even when using indoors, the lamp is a fairly bright light, sufficient well for all household purposes. During operations at night outside the high luminosity and long range but are only really clear. It's almost uncanny how still leave also areas that are 50 feet or more away, illuminate well.
Accessories:
The only sensible accessories is the size adjustable strap. The, also adjustable, for fixing Gurtbandkonstruktion as head lamp, in my opinion, can be thought of only as a gimmick, for no man running with a flashlight attached such on your own head around the area. The bike mount on the other hand is quite stable and functional. Using an LED flashlight in the dark as a substitute for a regular bike light, but I think is negligent and dangerous. Firstly, because the lateral illumination of the roadside area is lacking, partly because oncoming drivers can be dazzled by the massive highly focused light.
Batteries:
Uses 3 small AAA batteries. Although these are not in, but these days fall in price hardly more significant. With the durability or the (not specified EasyAcc) power consumption I'm already more than satisfied, since I the lamp for several weeks on a regular basis, though only for about 1-2 minutes, use and yet had to change batteries , Alternatively, can be, moreover, battery use.
Not toys!
The optical lens of the flashlight acts like a magnifying glass. As the bright white light of LEDs not only other dazzling, but also in Multi-second radiation directly into the eye (and here add up individual time intervals!) Can cause retinal damage, the manufacturer warns good reason not to look NEVER directly in the light of the flashlight , Even if the intended use is of course problematic and dangerous, this lamp is definitely not for little kids!
Conclusion:
Great flashlight at a low price with high brightness and range, but not a full replacement for a header or bike light. Knappe 5 Stars!
