My Surefire G2 was late 90s so with the lightest on the market, now it was only a dim candle in comparison with modern lamps. So I attempted to give her an upgrade. With Success! The fairly quickly delivered reflector with the hilarious translation "Spring" instead of "spring" (Spring!) In the description fit only not good, the lamp head could be not quite turn. But I remembered "please remove install the outer spring before the Lamp". From the item description Behold, settled the great spring and already everything was great and even light properly. The LED reflector has definitely not 820 lumens. I have compared him in the dark with a Olight S20 Baton which has 550 lumens. The performance is shown below, but is absolutely ok So it could well be 400 lumens. When you consider that the G2 before had 60 lumens or 120 lumens with the high-performance reflector that sucks the expensive batteries empty in a quarter of an hour, it is now again a great flashlight that can keep up with the modern parts. And all this for really small money. Only the service is a bit annoying, so only 4 stars. Each time you press the power button within 3 seconds, the mode changes. Only full, half, then Strobo and over again. The lamp in quick succession to turn is not possible without them every time the mode changes, including in the stroboscopic mode.
