The steps are as follows:

Step 1: Unscrew the back cover of the battery and remove the battery.

Step 2: head flashlight lens, you can see a circle with two small round holes, with a small clamp to remove the light bulb.

Step 3: Look in from the front of the flashlight. You can see a half-round spring pin with two small round holes. Take it out with a clamp.

Step 4: Take out the parts that can charge and push the button. The torch is disassembled.

Expanding knowledge:

Strong light flashlight is a new lighting tool which uses light-emitting diode as light source. It has the advantages of energy saving, durability and strong brightness. Common strong light flashlight is a kind of outdoor lighting tool with high power light-emitting diode as the light source. It has the advantages of saving electricity, durability and high brightness.

At present, in addition to LED light source flashlight, there are HID xenon flashlight for special lighting.

LED light flashlight lamp cap has two ways of concentrating light, one is the concentrating cup, the other is the convex lens, the concentrating cup has better concentrating effect, light loss, light weight, can seal the part of the lamp cap is very strict, improve the waterproof effect,

The fly in the ointment is that the light spot can not be adjusted, so that when used, the near area is very small, and the biggest advantage of convex lens is the stepless adjustable light spot size, but it is difficult to do good waterproof, so the general outdoor sports enthusiasts will choose the former according to the environment.

The rated voltage is 3.7V. The capacity ranges from several hundred to several thousand milliampro-hours. Depending on the power of common LED light sources, the endurance ranges from dozens of minutes to several hours.

The eight virtues

1, environmental protection lamps, protect the earth – traditional fluorescent lamp contains a lot of mercury vapor, if broken mercury vapor will volatilize into the atmosphere. But led flashlights do not use mercury at all, and LED products do not contain lead, to protect the environment. Led flashlights are recognized as the green lighting of the 21st century.

2, efficient conversion, reduce heat – traditional lamps and lanterns will produce a lot of heat, and LED lamps and lanterns is to convert all the electricity into light energy, will not cause energy waste. And the documents, clothing will not produce fading phenomenon.

3, quiet and comfortable, no noise — LED flashlight will not produce noise, for the use of precision electronic instruments for the occasion of the best choice. Perfect for libraries, offices, things like that.

4. Light is soft and protects your eyes — traditional fluorescent lamps use alternating current, so they produce 100-120 strobograms per second. Led flashlight is a direct conversion of ALTERNATING current to direct current, no flicker phenomenon, protect eyes.

5, no UV, no mosquitoes – LED flashlight will not produce UV, so not like the traditional lamps, there are a lot of mosquitoes around the lamp source. The interior will become more clean and tidy.

6, the voltage can be adjusted 80V-245V – the traditional fluorescent lamp is released by the rectifier of the high voltage to light, when the voltage is reduced can not be lit. The led flashlight can be lit within a certain range of voltage, but also adjust the brightness.

7, save energy, longer life – led flashlight power consumption is less than 1/3 of the traditional fluorescent lamp, life is 1000 times the traditional fluorescent lamp, can be used for a long time without replacement, reduce labor costs. More suitable for difficult to change the situation.

8, strong, long use — LED flashlight body itself is epoxy resin rather than traditional glass, more solid, even if hit the floor LED will not be easily damaged, can be safely used.
