Instructions for use of LED flashlight:

1. Check the battery for the strong light LED flashlight: make sure the battery is charged and insert the battery in the correct direction.
2. When using a strong light bulb: choose according to the voltage and battery requirements of the torch. Do not use it indiscriminately to avoid burning the circuit board. Please do not mix batteries of different types and voltages.

3. When using, when the brightness of the flashlight changes significantly, remember to turn off the flashlight to prevent over-discharge of the battery. In addition, pay attention to the waterproof, moisture-proof, and drop-proof of the battery. When the indicator light turns from red to yellow, please take out the battery as soon as possible, do not overcharge.
4. If the battery is not used for a long time, the battery should be fully charged and stored. Under normal circumstances, it should be charged and discharged again in about three months to avoid chemical corrosion.
5. Keep the inside of the lamp wall clean, never try it with your hands or hard objects, remove fingerprints or yo, and use a cotton swab dipped in lens cleaner to wipe gently.
6. Please do not keep the flashlight in contact with sunlight, water, chemicals and corrosive gases for a long time to avoid damaging the protective layer of the flashlight.
7. Non-professionals should not disassemble the flashlight to prevent damage to the circuit board. When your flashlight fails, you can send it to the LED flashlight factory to repair it for you!
