For the first time, remember to remove the insulating sheet from the battery.

The LED chip in this flashlight is super powerful and can produce up to 10000 lumens. It can last up to 50,000 hours, and it's normal for it to get a bit warm during use. If it doesn't work right, try charging it for 1-2 hours.

The flashlight has four power indicators. When all four lights are on, it's fully charged. Three lights mean it's at 75%, two lights mean it's at 50%, and one light means it's at 25%. If you only see one light, it's time to charge it. Just remember to turn it off before charging.

You can adjust the flashlight to three different settings by rotating it. You can use it as a spotlight for long-distance viewing or as a floodlight for wider lighting. It also has two flash modes: a flashing light to grab attention and an SOS mode for emergency situations.

This flashlight is waterproof and works great in all kinds of weather. It's also lightweight and small enough to use for self-defense. The aluminum body is strong and can withstand rough handling. Just remember not to submerge it in water.
