The flashlight is made of aluminum alloy and is very small, so it will fit in any pocket. It has a high-intensity CREE XP-E LED light with a reflector and a glass lens. The zoom function allows you to continuously adjust the beam by extending the front of the lamp. You can switch between the three lighting modes (full, energy saving and flashing) with the button on the back of the lamp. There you will also find a practical loop for hanging on your hand or backpack. The flashlight has a Li-Ion battery (400mAh), which you can easily charge with the included cable in just 2 hours.
