In fact, the lamp has a great deal for the price. Even the packaging is very high quality and the delivered content is great, without criticisms. In the box there is:
-a package batteries (3 pieces of Duracell)
-3 Different rings, 2 Transparent, each in red and white (to be viewed from the side) and an opaque ring
-The bracket with several rubber fins to adjust the width of the Länkerdicke
-Of course, the lamp itself
The build quality is impeccable (at least on my model). The lamp is made of metal and is very valuable to almost all items sit and watch, no rattles. The holder is made of plastic, although that should not be a disadvantage, I saw a lot of good, safe plastic holders. 2 wheel for horizontal and vertical adjustment are located on the mount, and a "hold" on the lamp. All wheels turn easily and do not seem to give in, so the thread actually work.
Now for what really makes the lamp: the light
For the street lamp is clearly too bright (at least 100% mode). Switching between modes is possible by repeatedly pressing the switch, the pause between pressing decides whether switched to another mode or back to 100 % is changed, sounds at first a bit complicated, it is at first too, but provides for (very) short acclimatization no longer a problem. The setting of the "focus", ie the light scattering or the width of the cone is not a problem here dissembled Beam width even when not driving on bumpy terrain.
Unfortunately, I had a greater effect expected by adjusting the light cone, what is also the first point of criticism for me.
Now the brightness:
As I said, the lamp for the road in 100% mode too bright, but should any of weaker level satisfactory. It should be noted here that the lamp has not street legal!
What about on the ground?
In my MTB Group, we are usually so about 10 riders which a wide range of lamps have so I had a good compared to other lamps. Lupine to Busch & Müller, as well as DIY and more. Granted, the lamp costs partly 1/3 and even less of the other lamps and thus the comparison is unfair, but it's also just the general MTB suitability and not to the actual brightness.
WHILE the others had no problems, but I struggled with the rather dark, the light cone is simply not enough and is not bright enough for fast off-road driving. Also the fact that there is no way for helmet mounting the lamp is not so good. I do not think the lamp therefore for MTB-compatible if it is the only lamp which is to be used. Maybe the light is not enough if you use 2 or 3 of the lights, but I'll try.
How long will the batteries last?
My Duracell held several tours (about 2-3 hours long) and a little play around after receiving the lamp (so frequent on and off) by. I consider the term to be sufficient and acceptable when you look at the brightness and ultra low form factor.
Conclusion:
What can I say in conclusion therefore now? The lamp you get a favorable, for the price amazingly bright, superbly processed lamp which is small and light. As sole light source in harder terrain it is not good, however. For the road, it is, however much too bright. So what is the purpose? so I'm a little stumped ... maybe as cheap additional lamp on the handlebars, along with a good (much more expensive) helmet lamp, or for simple routes without street lighting (eg good field and forest paths without roots and bumps) but nothing more.
Pros and Cons:
+ Small and light
+ Sufficient maturity
+ Excellent workmanship
+ Excellent for the city in lower mode
+ Ordinary bracket (at my pretty straight, relatively thin handlebar)
-As a sole light source is not bright enough
Effect of beam focusing lower than expected (falls for me eventually but not as significant since it usually always used the biggest spread around as much as possible of the route illuminate directly against a)
-Not the helmet fastened
Ultimately, however, still good 3/5 star, who is a high-quality lamp for street and dirt road might look for will love this lamp!
