General Introduction

SH7900 Aluminium flashlight with Digital Ring-Switch on head & Tactical On/Off Switch on end cap



Digital 360° Ring-Switch
Digital Ring-Switch 12 modes control ring switch, 6 permanent bright modes, 3 SOS modes, 3 flash signal modes, 360° ring-switch design, extremely smoothly to operate.

Power switch is located at tail cap, press for momentary on, click for constant on /off.

Water resistant 30M

Built-in micro controller. Regulated circuit designed, which can take 100% utilization of the batteries, extended battery life. (When using 2 AA 2700 Ni-MH batteries at 6th permanent bright mode (lowest output) is up to 70 hours battery life time.)
It can works in the -25°C.

LED lifetime is as long as 100,000 hours
CREE High Power LED, lifetime up to 100,000 hours.


Computer- Calculating collimator Lens
Collimator optical lens with superior quality can optimize to conduct LED light beam via the computer, the spotlight result is substantially promoted, and light distance get farther!


Aluminum Alloy Heat-Sink Structure 
it is dandy to dispel the heat. The Aluminum Alloy Heat-Sink Structure can efficiently promote LED to give out maximum light output, and prevent LED degrade cause of over-heatedly.

Q:Explosion proof of LED flashlight
Explosion proof standard is GB3836, if you do the flashlight should be intrinsically safe in nature, according to the standard GB3836.1 and GB3836.4,. The concept of explosion protection certification is incorrect, but only the products you have obtained are qualified for explosion protection. If you do mine, first from the product security application began, I am not certified companies, nor do certification, but there are questions you can ask, without any fees. Ha-ha
Q:What are the LED flashlight bulb?
You can see the wolf lomen etc. These are surefire online selling, sales in the very front
Q:Who can tell the difference between the LED flashlight, the wick XML and the previous ones?.
The XML series is the CREE company in the United States shortly before the launch of the LED fans dubbed it as "Little Donkey", its characteristic is: high brightness (XML-T6 to 860 lumens), high power consumption (XML-T6 full power drive current 3A), low turn-on voltage, the luminous efficiency is high, should pay attention to the problem of battery capacity, contact resistance and heat dissipation of normal use.
Q:What's the advantage of LED flashlights?
Outdoor activities, we are trying to minimize things, so in the flashlight, we should try to use efficient light LED flashlight, to ensure sufficient brightness and long endurance.
Q:What are the categories of LED flashlights?
The number of lamp caps (i.e., LED) ranges from 10 to twenty or thirty, with more than more than 40 lamps. Most of the shell of the torch is made of aluminium alloy. The switch of the torch is set at the tail part, and some are arranged on the side of the front part. The front side switch is more convenient to use. The ignition voltage of high brightness LED about 3V, so the LED flashlight uses three AAA batteries without booster can be directly lit, so the power supply efficiency is high, only a small energy consumption in the current limiting resistor. It should be noted that not the more LED, the better. Qi Jie automotive supplies experts advise, but also pay attention to see if there is a better quality reflector film behind the lamp cover, it can reflect the light scattered by LED, and can improve the brightness of the flashlight 20%~30%. The main disadvantage of the multi burner flashlight is that the focusing effect is not good, and the spotlight effect is not better than that of the ordinary flashlight, so that the light is not bright enough when irradiated on a far distance object.
Q:How can a rechargeable flashlight LED light bulb be judged by a multimeter?
Upstairs said yes, pointer multimeter, with 10K files, you can also use mobile phone batteries, the number of connected, on the bright, the wrong connection is not bright, how to connect also does not light, that is broken, this light is afraid to turn on the lights when the power.
Q:What is the current when charging an ordinary LED flashlight?
Typically nine light-emitting tubes, the rechargeable battery is usually around 1Ah, charging current of about two hundred ma.
Q:In the light rechargeable flashlight is how much?
LED (light emitting diode) is English, LED lamp is a light emitting diode of the English abbreviation LED, this is a popular name.
Q:LED flashlight off the ground, it is not enough electricity, what happened?
Maybe it's a short circuit. I'd like to buy a good quality tank007 flashlight
Q:What are the disadvantages of a LED flashlight?
The disadvantage is the heat problem, if the poor heat dissipation will greatly shorten the life, flashlight factory in the design and production, need to fully consider the heat problem of flashlight, so as to avoid unnecessary damage.
