1, our flashlight uses advanced constant-current technique can effectively address the constant-current LED flashlight's requirements.
2, special instruction: a. do not pressure, voltage do not exceed 4.2V b. battery positive forward, not reverse, otherwise it will burn plate c. attention to control the torch temperature changes, ensuring heat d. non-professionals do not open circuit board
3, warranty description: open circuit is no longer under warranty or addressed.
III. lithium battery instructions
1, the main 18650 lithium battery flashlight with batteries.
2, characteristics of lithium-ion batteries: lithium battery and cell phone batteries charged totally different ways; Lithium-ion batteries do not have memory and can be filled at any time, do not overcharge.
3, charging at least 6 hours for the first time, according to the charger the green light then it is possible. Not overcharge.
4, natural discharge rate of the lithium battery when not in use, will release its full range of about 1% per day or less, although slowly, but prevent prolonged storage time.
5, notice that batteries waterproof, anti-and shatter-resistant and so on.
6, special tip to use against overcharge, anti-, short circuit-proof ' proof ' charger
7, the battery is not used for a long time, should save power full, normal discharge about once in three months;
8, warranty description: battery factory is no longer under warranty.
IV. flashlight specifications
1, torches in use, according to torch the requirements for voltage and battery choice, not to prevent burn circuit boards, different models, different voltage of battery do not use both.
2, in use, when the obvious changes in the brightness of the torch, to turn off the flashlight, preventing battery overcharge.
3, cooling techniques: the torch is in use, to ensure the heat. Strongly required when battery is fully charged, it is best to use second gear, be extended so that we can let the torch lamp and battery life! Hand held torch is the best heat dissipation; Suggest that lights up according to the heating time of the torch cooling or closed down and then lit, so that the heat sink.
4, flashlight waterproof, shock-proof and so on the explanation and awareness.
5, light Cup walls keep it clean, you must not use hand or hard objects to clean; Chen Jing of Qing dynasty on-chip fingerprint used cotton swabs dipped the lens cleaner and gently wipe.

Flashlight to purchase a few of the common errors
Myth one: higher brightness is not good

Flashlight method to enhance the brightness from the lamp to the reflector, battery, design comprehensive upgrading of main plate. The big international and domestic brand-name products, have gone through a rigorous design and testing to ensure life and security.
Second method is achieved by increasing the voltage and current: overclocking of the foot after heating is huge, because there is no match, leading to frequent burning lamp and the lithium-ion battery frequently discharges, can light up for a few minutes and are often in need of repair.
Myth: being misled by false arguments
Many sellers intentionally or unintentionally false lumen value
Myth three: orange peel reflector is not necessarily better than the glossy
Orange peel reflector reflecting lower efficiency than smooth, powerful search lights you can see the market is basically smooth Bowl, because reflective high efficiency range. So why do most tactical flashlight with orange reflective dishes? The reason is simple, in order to obtain a perfect spot. Because we generally use light bulbs with a filament, reflector reflected light spot happens to be the projection of the filament, the principle of which is similar to the phase of the convex lens. This spot is a clear filament, it is difficult to see. We take parameters but also to look at the actual results!
True mark of this shop sells flashlight brightness, long battery life, light colored pure white, perfect focusing effect! Engineering, field sports, such as excellent tools!
The flashlight has the advantages: compact size, light weight, easy to carry, durable, use function light strong, direct distance, weak light to choose light-when the low light--a recent photo, in case of emergency--explosive Flash. Titanium oxide enhancing the attack hit a design on the top, can be replaced in case of emergency hammer to smash Windows to escape.
"Frequently asked questions"
Q: do I need to first charge use?
A: Please use of the flashlight when dark spots, then charge for 4 hours and then use fear over discharge lithium battery, please form usually charging habits.
