INCLUDE battery

I. Instructions for using the switch
1, the battery is positive pole facing inward (lamp side), negative pole facing outward (tail).
2, the switch is at the tail, the switch function Chengan switch is the switch function, lightly press the switch is the dimming function.

II.  Circuit board instructions for use
1, the store torch using advanced voltage regulator constant current technology, can effectively solve the LED torch requirements for voltage regulator constant current.
2, special tips: a. Do not over-voltage use, the voltage should not exceed 4.2V b. Battery positive root towards the front, do not invert, otherwise it will burn the board c. Note the change in temperature control torch to ensure heat dissipation d. non-professionals do not open the circuit board
3, warranty instructions: open or handle the circuit board is no longer covered by warranty.

III.  Lithium battery use instructions
1, most of the flashlight battery mainly with 26650 lithium battery.
2, lithium battery characteristics: lithium batteries and cell phone battery charging method is completely different;  lithium batteries do not have memory, can be charged at any time, do not overcharge over discharge.
3, the first charge for at least 6 hours, and then according to the charger green light is on.  There is no need to overcharge.
4, the natural discharge rate of lithium batteries when not in use, about 1% or less of its daily charge will be released, although slow, but to prevent the placement of time too long.
5, pay attention to the battery's waterproof, anti-term, anti-drop, etc.
6, special tips to use anti-overcharge, anti-reverse connection, anti-short circuit "three anti" charger;
7, long time not to use the battery, should be full of power to save, normal in about three months and then charged and discharged once;
8, warranty: the battery is no longer covered by the warranty after the factory

IV. Instructions for use of the flashlight
1, the flashlight in use, according to the requirements of the flashlight on the voltage and battery selection, do not use indiscriminately to prevent burned circuit boards, different models, different voltage batteries do not use at the same time.
2, in use, when the flashlight brightness changes significantly to turn off the flashlight, to prevent the battery from being overdischarged.
3, heat dissipation skills: flashlight in use, to ensure heat dissipation. It is strongly recommended that when the battery is fully charged, use the second gear first, so that the torch head and the battery can get extended product life! Hold the torch by hand is a good heat dissipation Wan style; it is recommended to put the light to be timely heat dissipation or close according to the heat of the torch, to be cooled down and then light up in order to dissipate heat.
4, for the torch on waterproof, shockproof, etc. instructions to strengthen the prevention.
5, the inside of the lamp cup to keep clean, can not be wiped with hands or harder objects; Qing Chen lens on the fingerprints, available cotton swab jiao lens cleaner gently wipe test.
6, can not be the torch light directly into the eyes of people, so as not to affect the eyesight, especially children.
7, if you do not use the flashlight for a long time, please take out the battery (a month or longer) to avoid chemical corrosion.

V. Protection instructions
1, do not put the torch long-term contact with sunlight, water, chemicals and corrosive gases, etc., to avoid damage to the protective layer of the torch.
2, in order to keep the "0" ring and threads rotating smoothly, according to 2-3 times a year in its surface rubbing petroleum jelly, etc.

VI. Troubleshooting
1、Check the battery: make sure the battery is charged and installed according to the correct direction, do not use different brands of batteries, old and new batteries can not be mixed.
2, check the tail cover: ensure that the switch has been tightened and good contact, ensure that the tail cover copper column and tail cover pressure ring metal contact is good.
3, pay attention to whether the light head is loose.

Several common misconceptions about the purchase of flashlights

Myth 1: Brightness is not the higher the better
Flashlight to enhance the brightness of a method from the head to the reflector bowl, battery, the main trigger design and other comprehensive upgrade.  International brands and domestic brand-name products, have undergone rigorous design and testing to ensure service life and safety.
Method two is the use of increased voltage and current to achieve: overclocking brings the rear of the foot fever huge, because the two do not match, resulting in frequent burning lamp head and lithium batteries often over discharge, only a few minutes to light and often need repair.

Misconception two: misled by false parameters
Many sellers intentionally or unintentionally false lumen values

Misconception three: orange peel reflective bowl may not be better than the glossy
The reflective efficiency of the orange peel reflector bowl is lower than the glossy one, and you can find that the high-power search lights on the market are basically glossy bowls because of their high reflective efficiency and long range.  So why do most tactical flashlights use orange peel reflective bowls?  The reason is simple, in order to get a perfect light spot.  Because we generally use the light bulb is a filament, and the reflective bowl reflects the light spot is exactly a filament projection, the principle is similar to the principle of convex lens into the phase.  This spot is a clear filament, it is difficult to see.  We look at the parameters more to see the actual effect!
We sell flashlights real marked brightness, long battery life, light color pure and transparent white, good light gathering effect!  Is work, field sports and other excellent auxiliary tools!
The advantages of this flashlight: compact size, light weight, easy to carry, durable, with all-weather use, strong light, direct shooting distance, strong and weak light can be selected, strong light - far, low light - near light, emergency - - burst flash.  -explosive flash.  Top oxidized titanium alloy to strengthen the attack a head of design, can be used in an emergency instead of a safety hammer to smash the car window escape.

Frequently Asked Questions
Q: need to charge first before use?
A: Please use first, and so the flashlight light darker, and then charge 4 hours before use, lithium batteries are most afraid of over-discharge, please develop the usual charging habits.
Q: What is the lithium battery over-discharge?
A: The brightness is obviously weakened also continue to use, the resulting battery damage, even after professional activation by making, the power will be significantly reduced, so usually please pay attention to the maintenance of the battery, charge more.
Strong flashlight use precautions
Do not often disassemble the light head, so as not to cause reflector or bulb damage.

Strong light flashlight maintenance precautions
When using the flashlight, please carry out daily routine maintenance so that it can continue to provide you with high quality service
1.  Wipe the flashlight with a clean soft cloth after each use.
2.  When the torch is stained with seawater or corrosive liquid, please clean it with water and dry it with a hairdryer in time.
3.  When the head and tail cap are not screwed smoothly, please apply a small amount of silicone grease at the interface.
4.  When the torch is not in use, please take out the battery and store it in a cool place.
