The adjustable focus head with a manual extension, similar to the lens of a camera, forms different light spots by changing the focal length.Optical mouth lens.X 1 time for optical focusing, the effective light collection is 99.6%, with no glare. The focused spot of light is clear enough to see the clear structure of the chip light emitting surface. However, digital cameras can't handle such a large contrast, and it's difficult to see in the photos.At X2000, the optical diffuser is used, resulting in a uniform light spot, suitable for projection. There are no concentrated light points. The diffused light spot is very uniform, making reading comfortable without any fatigue.

1. Switch Usage Instructions
1. The battery is positioned with the positive terminal facing in (towards the bulb end) and the negative terminal facing out (towards the tail end).
2. The switch is located at the tail, and the switch function is the same as the safety switch. Pressing lightly on the switch is the dimming function.
Section 2: Circuit Board Usage Instructions
1. The flashlights in our store adopt advanced voltage stabilization and constant-current technology, which can effectively meet the requirements of LED flashlights for voltage stabilization and constant-current.
2. Special Notes: a. Please do not use the product under excessive pressure; the voltage should not exceed 4.2V. b. Ensure that the positive terminal of the battery is facing forward; do not reverse it, or the board may be damaged. c. Pay attention to the changes in the temperature of the flashlight to ensure proper heat dissipation. d. Please do not open the circuit board unless you are a professional.
3. Warranty Statement: The warranty does not cover opened or handled circuit boards.
Section 3: Lithium Battery Usage Instructions
1. Features of Lithium Batteries: Lithium batteries have a completely different charging method from mobile phone batteries; Lithium batteries have no memory effect, and they can be charged at any time, but they should not be overcharged or overdischarged.
2. The first charge should last at least 6 hours, and after that, it's enough as long as the charger's green light turns on. There's no need to overcharge.
3. Special Note: Use a "Three Defense" charger with overcharge protection, reverse connection protection, and short circuit protection.
4. If the battery is not used for a long time, it should be fully charged and stored. It is recommended to charge and discharge it again every three months or so.
Section 4: Instructions for Using Torches
1. When using the flashlight, choose it based on the requirements of the flashlight for voltage and batteries. Do not use it randomly to prevent burning out the circuit board. Do not use batteries of different models and voltages at the same time.
2. When using the flashlight, turn it off if the brightness significantly changes to prevent the battery from being over-discharged.
3. Heat dissipation tips: Ensure that the flashlight dissipates heat during use. It is strongly recommended to start with the second level when the battery is fully charged to extend the life of the flashlight head and the battery! Do not direct the flashlight beam into someone's eyes, as the bright light can be blinding and may affect vision, especially for children.
Fault Inspection and Maintenance
1. Check the battery: Ensure that the battery is charged and installed in the correct direction. Do not use batteries from different brands, and do not mix new and old batteries.
2. Check the tail cover: Ensure that the switch is tightened and in good contact, and that the metal contact between the tail cover's copper column and the press ring is good. Also, ensure that the lamp head is not loose.
