About this item USB rechargeable: battery is not included in the package. When the flashlight is charging, the switch button is red, and when charging is complete, the switch button is green (Note: When using the battery for the first time, please remove the film) . 4 Light Modes: Our LED flashlight is 600 lumens with 4 light modes (high, low, strobe and SOS) for our daily use, it is bright enough to use as a dedicated flashlight or just for emergencies (note: after strobe mode, you need to long press for three seconds, then switch to fourth mode - SOS). DURABLE METAL CLIP: The compact clip looks sturdier and prevents the flashlight from rolling too far on a flat surface, so the flashlight can be kept in your pocket and ready to go.

Versatile use: IPX4 waterproof, our LED flashlights work in the rain, perfect for camping, hiking, fishing , running, walking, power outages, emergencies, targeted searches and general home use.
