The flashlight is powered by one 18650 battery or three AAA batteries (batteries not included and must be purchased separately). The battery can be charged very quickly using the supplied USB charger. 
The powerful Luminus SST-40-W LED provides powerful light and has a long lifespan, so you don't have to worry about frequent replacement. The light has a brightness of 1000 lumens and its range is 300 meters. The flashlight has 5 lighting modes. 3 modes are used to control brightness (strong, medium, low), and the other two are used to turn on strobe light or SOS. To switch between modes, use the flashlight switch.
Waterproof
The flashlight is resistant to splashes, so you can easily use it in the rain or in other humid conditions. During ordinary use, this is quite sufficient.
ZOOM function
The Superfire F3-L2 flashlight has the ability to focus the beam by extending the head of the flashlight, thanks to which we will see the illuminated area very accurately.
