Instructions for Using High-Light Flashlights
1. Instructions for Using the Switch
1. The battery has the positive electrode facing inward (toward the lamp head), and the negative electrode facing outward (at the tail).
2. The switch is located at the rear; the switch function includes a dimming function, while a light press activates the dimming mode.
2. Circuit Board Instructions
1. The store's flashlight utilizes advanced voltage regulation and constant current technology, which effectively meets the requirements for voltage regulation and constant current in LED flashlights.
2. Special notes: a. Do not use above the specified pressure; voltage should not exceed 4.2V. b. The positive terminal of the battery should face forward; do not reverse it, otherwise the board may burn out. c. Pay attention to controlling the temperature change of the flashlight to ensure proper cooling. d. Do not open the circuit board by non-professionals.
3. Warranty instructions: Circuit boards that have been opened or processed are no longer covered by the warranty.
3. Lithium Battery Usage Instructions
1. Most flashlight batteries mainly use 18650 and 16340 lithium batteries.
2. Characteristics of lithium batteries: The charging methods for lithium batteries and mobile phone batteries are completely different; lithium batteries have no memory effect, can be charged at any time, and should not be overcharged or over-discharged.
3. The first charge should take at least 6 hours; thereafter, it can be done once the green light on the charger turns on. There is no need to overcharge.
4. The natural discharge rate of lithium batteries releases approximately 1% or less of its charge per day when not in use. Although slow, this prevents prolonged storage.
5. Pay attention to the battery’s waterproof, durability, and shock resistance.
6. Special note: Use a charger with “three protections” such as overcharge protection, reverse connection protection, and short-circuit protection;
7. If the battery is not used for a long time, charge it to full and store it. Normally, charge and discharge it once every three months.
8. Warranty instructions: The battery is out of warranty after leaving the factory.
4. Instructions for Using a Flashlight
1. When using a flashlight, choose it based on its voltage and battery requirements. Do not use it indiscriminately to avoid damaging the circuit board. Do not use batteries of different models or voltages simultaneously.
2. During use, turn off the flashlight if its brightness changes significantly to prevent over-discharge of the battery.
3. Cooling techniques: During use, ensure proper cooling of the flashlight. It is highly recommended to use level 2 setting when the battery is fully charged, as this can extend the lifespan of both the light head and the battery! Holding the flashlight tightly with hands is an effective cooling method; it is advised to dissipate heat promptly or turn off the flashlight while powered on depending on its heat generation, and turn it back on only after the temperature has dropped, to facilitate cooling.
4. Strengthen measures to prevent water damage and shock resistance regarding the flashlight.
5. Keep the inner wall of the lamp cup clean; do not use hands or hard objects to wipe it. To remove fingerprints from the lens, gently clean it with a cotton swab dipped in lens cleaner.
6. Do not direct the light from the flashlight straight into people’s eyes, as this may affect vision, especially for children.
7. If the flashlight is not used for a long time, remove the battery (for one month or longer) to prevent chemical corrosion.
5. Protection Instructions
1. Do not expose the flashlight to sunlight, water, chemical substances, and corrosive gases for long periods of time to prevent damage to the protective layer of the flashlight.
2. To ensure smooth rotation of the “0” type ring and threads, wipe their surface with vaseline oil 2–3 times per year.
6. Fault Diagnosis and Repair
1. Check the battery: Ensure the battery is charged and installed in the correct direction. Do not use batteries of different brands, and do not mix old and new batteries.
2. Check the tail cover: Ensure the switch is tightened properly and has good contact, and guarantee that the copper post of the tail cover contacts well with the metal piece of the pressure ring.
3. Check if the light bulb socket is loose.

Several Common Misconceptions When Choosing Flashlights
Misconception 1: Higher brightness is not always better

One way to increase the brightness of a flashlight is to improve the design across various components such as the head, reflector bowl, battery, and main switch. Both international and domestic brand products undergo rigorous design and testing to ensure their lifespan and safety.
Method two involves increasing the voltage and current: overclocking causes significant heat generation, and due to the mismatch between them, the bulb and lithium battery experience frequent overdischarge. As a result, it can only light up for a few minutes and often requires maintenance.
Misconception Two: Being Misled by False Parameters
Many sellers intentionally or unintentionally overstate the lumens value.
Misconception 3: A peeling-skin reflective bowl may not necessarily be better than a smooth surface one
The reflection efficiency of the orange-patterned reflective bowl is lower than that of the smooth surface type. It can be seen that most high-power search lights on the market use smooth surface bowls because they have higher reflection efficiency and longer range. So why do most tactical flashlights use orange-patterned reflective bowls? The reason is simple: to achieve a perfect light spot. Since the bulbs we typically use have filaments, the light spot reflected by the reflective bowl happens to be a projection of the filament, similar to the imaging principle of a convex lens. As a result, the light spot appears as a clear filament, which is not attractive. When checking parameters, we must also consider the actual performance!
The flashlights sold by this store have accurately indicated their brightness, long battery life, pure and bright light color, and excellent focusing performance! They are excellent auxiliary tools for work and outdoor activities!
Advantages of this flashlight: compact size, light weight, easy to carry, durable and robust, capable of operation throughout all weather conditions, strong illumination with long direct beam range, adjustable between high and low light levels—strong light for distant areas, low light for close proximity, and flash function in emergencies. The top is reinforced with titanium alloy, allowing it to serve as a safety hammer to break window glass during emergencies for escape.
【Common Questions】
Question: Do I need to charge first before using?
Answer: Please use it first. Wait until the flashlight light becomes dim, then charge it for 4 hours before using again. Lithium batteries are most vulnerable to over-discharge; please develop the habit of charging regularly.
Question: What should I do if the light bulb is broken?
Answer: If the light fails unexpectedly and gets damaged, you can contact us for a discounted replacement.
Question: What is over-discharge of lithium batteries?
Answer: Continuing to use the device with significantly reduced brightness can cause battery damage. Even after professional activation, the battery capacity will decrease noticeably. Therefore, please pay attention to maintaining the battery properly and charge it frequently.
Precautions for using high-intensity flashlights
Do not frequently disassemble the lamp base to avoid damage to the reflector cup or bulb.
Maintenance Precautions for High-Light Flashlights
Please perform regular maintenance on the flashlight during use to ensure it continues to provide you with high-quality service.
1. After each use, please wipe the flashlight with a clean, soft cloth.
2. When the flashlight gets contaminated with seawater or corrosive liquids, promptly clean it with clean water and dry it with a hairdryer.
3. When the lamp head and tail cap do not turn smoothly, apply a small amount of silicone grease at the interface.
4. When not in use, remove the battery and store it in a cool place.
