Instructions for Using a Powerful flashlight
one Switch Usage Instructions
1. The battery should have the positive terminal facing inward (towards the lamp head) and the negative terminal facing outward (at the tail).
2. The switch is at the rear. The switch function is the switch function. Pressing the switch lightly is the dimming function.
two Circuit Board Usage Instructions
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. Do not use under overvoltage. The voltage should not exceed 4.2V. b. The battery should be placed with the front end facing forward. Do not reverse it, otherwise the board may burn out. c. Pay attention to controlling the temperature changes of the flashlight to ensure heat dissipation. d. Non-professionals are not allowed to open the circuit board
3. Warranty Description: Open or processed circuit boards are no longer covered by the warranty.
Three Lithium Battery Usage Instructions
Most flashlight batteries mainly use 18650 and 16340 lithium batteries.
2. Characteristics of lithium batteries: The charging methods of lithium batteries are completely different from those of mobile phone batteries. Lithium batteries have no memory effect and can be charged at any time. Do not overcharge or overdischarge them.
3. The first charge should last at least 6 hours. After that, it's fine when the green light on the charger is on. There's no need to overcharge.
4. When not in use, the natural discharge rate of lithium batteries is approximately 1% or less of their charge per day. Although it is slow, it is necessary to prevent them from being stored for too long.
5. Pay attention to the battery's water resistance, durability, and protection against drops, etc.
6. Special reminder: Use a charger with "three-proof" features that prevent overcharging, reverse connection, and short circuit.
7. If the battery is not used for a long time, it should be fully charged and stored. It is normal to charge and discharge it once every three months or so.
8. Warranty Description: The battery is no longer covered by warranty after leaving the factory.
Four Instructions for using the flashlight
When using a flashlight, select it based on the voltage and battery requirements of the flashlight. Do not use it randomly to prevent the circuit board from being burned out. Do not use batteries of different models and voltages simultaneously.
2. During use, when the brightness of the flashlight changes significantly, turn it off to prevent over-discharging the battery.
3. Heat dissipation tips: During the use of the flashlight, ensure proper heat dissipation. It is strongly recommended that when the battery is fully charged, use the second gear first. This can extend the lifespan of the flashlight's lamp head and battery! Holding the flashlight tightly in your hand is a good way to dissipate heat. It is recommended that when the flashlight is lit, it should be cooled down or turned off in a timely manner according to the heat generated by the flashlight. Wait until the temperature drops before lighting it again to facilitate heat dissipation.
4. Enhance precautions in light of the flashlight's instructions on water resistance, shock resistance, etc.
5. Keep the inner wall of the lamp cup clean and do not wipe it with your hands or hard objects. To remove fingerprints from the lenses, you can use a cotton swab dipped in lens cleaner to gently wipe them.
6. Do not shine the flashlight directly into people's eyes to avoid affecting their eyesight, especially for children.
7. If the flashlight is not used for a long time (one month or longer), please remove the battery to avoid chemical corrosion.
Five Protection Instructions
Do not expose the flashlight to sunlight, water, chemicals or corrosive gases for a long time to avoid damaging the protective layer of the flashlight.
2. To ensure smooth rotation of the "0" ring and the thread, apply vaseline oil or similar substances to their surfaces 2 to 3 times a year.
Six Fault repair
1. Check the battery: Make sure the battery is charged and installed in the correct direction. Do not use batteries of 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 guarantee that the copper column of the tail cover is in good contact with the metal sheet of the tail cover pressure ring.
3. Pay attention to whether the lamp cap is loose.

Several common misunderstandings when choosing a flashlight
Misconception 1: Higher brightness is not necessarily better

One way to enhance the brightness of a flashlight is to comprehensively improve the design from the lamp cap to the reflector bowl, battery, and main board. Both international big brands and domestic famous products have undergone rigorous design and testing to ensure their service life and safety.
The second method is to achieve this by increasing the voltage and current: The rear foot heat generated by overclocking is huge. Due to the mismatch between the two, it leads to frequent burning of the lamp head and frequent over-discharge of the lithium battery, which can only be lit for a few minutes and often requires maintenance.
Misconception Two: Being misled by false parameters
Many sellers intentionally or unintentionally falsely mark the lumen value
Misconception 3: Orange peel reflective bowls are not necessarily better than smooth ones
The reflective efficiency of orange peel reflective bowls is lower than that of smooth ones. You can find that the high-power search lamps on the market are basically made of smooth bowls because of their high reflective efficiency and long range. So why do most tactical flashlights use orange peel reflector bowls? The reason is very simple: to obtain a perfect light spot. Because the bulbs we usually use all have filaments, and the light spot reflected by the reflector bowl happens to be the projection of the filament, its principle is similar to the phase formation principle of a convex lens. In this way, the light spot becomes a clear filament and looks very ugly. When we look at the parameters, we should pay more attention to the actual effect!
The flashlights sold in our store are truly marked with brightness, have long battery life, pure and transparent white light color, and good focusing effect! It is an excellent auxiliary tool for work, outdoor sports, etc.!
The advantages of this flashlight are as follows: compact in size, light in weight, easy to carry, durable and sturdy, with all-weather usage function, strong light, long direct exposure distance, and the ability to choose between strong and weak light. Strong light for distant use, weak light for near use, and in an emergency, a burst flash. The top titanium alloy oxide reinforced attack end design can be used as a substitute for a safety hammer to smash car Windows for escape in an emergency.
"Frequently Asked Questions
Question: Do I need to charge it before using it?
Answer: Please use it first. When the flashlight's light dims, charge it for another 4 hours before use. Lithium batteries are most afraid of over-discharge. Please develop the habit of charging them regularly.
Question: What should I do if the light bulb is broken?
Answer: In case the lantern is unfortunately broken, you can contact us for a discounted exchange.
Question: What is over-discharge of lithium batteries?
Answer: If you continue to use the battery despite a significant reduction in brightness, it will cause battery damage. Even after professional activation, the battery capacity will still decrease significantly. Therefore, please pay attention to battery maintenance and charge it frequently in daily life.
Precautions for using a powerful flashlight
Do not frequently disassemble the lamp cap to avoid damaging the reflector or the bulb.
Precautions for maintaining high-intensity flashlights
When in use, please carry out daily routine maintenance on the flashlight to ensure it can continuously provide you with high-quality services
After each use, please wipe the flashlight with a clean soft cloth.
2. When the flashlight comes into contact with seawater or corrosive liquids, please clean it with clean water in time and dry it with a hair dryer.
3. When the lamp cap and tail cover are not turned smoothly, please apply a small amount of silicone grease at the interface.
When the flashlight is not in use, please remove the battery and store it in a cool place.
