As the owner of many Zweibrüder lamps, as well as its predecessor, the F1, I have to say that once again a really big step up from two brothers has been done in terms of brightness here. My Compliment. However, the specified burn time of 60 hours is a lie. After 2 (!) Hours, the lamp will start blinking (battery-empty-flash), both with the supplied 1860 battery, a third-party battery, as well as with alternative 2xCR123A alkaline batteries (which can be alternatively used) , The lamp has 3 modes: Very light, medium and dark. In "medium" and "dark" flickers the lamp atrocious. One knows this flickering auto taillights. So therefore it is said: either to let the lamp running on full power, or not at all. Everything else is very disturbing when nighttime walk / NC. Shooting at night with a mobile phone are thus only at full power (which is however automatically turned down after a while and thus flickers again) possible because the cameras (mobile phone, SLR) course record flicker with and ugly bars appear in the image.
The supplied strap should just throw away confidently equal, because after a short train tearing this and the expensive lamp falls to the ground and has hideous flaws. When replacing the bezel the whole appearance is falling apart and you hurt very easily, the mechanics and the optical lens. Likewise, this always dirt and dust inevitably with the optics.
As a longtime fan Two brothers here from me definitely no recommendation.
Example picture attached: these streaks appear when photographing something "dark" mode is illuminated by the lamp in the "medium" or.
