The best flashlight in the world



Because it is really good to use it depends on three aspects:

1. Follow your own heart to find (you must have a certain knowledge base),

2. Experience of using for a certain time,

3. Communicate with other tung oil (flashlight enthusiasts). If you really need a reliable flashlight and accompany your friends for a long time, why not spend more time understanding the basic knowledge? If you only need a low-end product for any use, the elegant Pavilion of the supermarket, for a long time, Kangming will be 10+ yuan. (that is, plastic case, which has a charging socket when the buttock is pushed open ~ ~)

I will discuss from four aspects:

The first part is the brand introduction of flashlight,

The second part is the general classification and simple structure of flashlight,

The third part is the food of Flashlight - battery,

Part four: selection skills and experience

The first part: the brand introduction of flashlight.

I can be divided into five categories: first, foreign brands, representing surefire, are the most famous tactical hand and electric manufacturers in the world; of course, not all foreign brands are high-grade, which should be clear first. Other brands, such as Maglite, Parken, energy and so on ~ ~ it is better to choose domestic high-end handcrafts!!! Surefire has the advantages of stable and reliable quality and high driving force, and the disadvantage is that it is expensive and relatively troublesome after-sales. E1dl is a kind of flashlight which can be used for surefire. It can be seen that it is more expensive. Ordinary people are generally reluctant to buy it. Hereinafter referred to as "SF"

2、 Domestic high-end brand flashlight, represented by Fenix, nitecore, olive and narid. Although these look like foreign brands, they are actually made in China! The advantages are reliable quality, good after-sales service, and a certain degree of pressure. Compared with surefire, it has a lot of high cost performance; the disadvantages are that the price is still expensive (some models), and the workmanship and quality control of some products of some brands are suspected to decline. Let me show you the classic tk22 [5] of the TK Series in Fenix. The price is 518, and the actual purchase price should be between 330-360 (see the fourth part for the specific reasons). The price is relatively cheap, but it is still difficult for many people to accept. Hereinafter referred to as "brand tube"

3、 Domestic low-end brands are represented by Supfire, Tanlu and iFire. As mentioned above, surefire is the real magic fire, so this support is obviously a Shanzhai, but in my personal opinion, its quality is relatively better in a pile of Shanzhai, and it is regarded as "high-end" among domestic low-end brands. The advantages are: cheap (almost no advantages); the disadvantages are poor quality, general after-sales, poor circuit, unsafe battery cells and so on. What's the climate for low-end goods? You know! Hereinafter referred to as "mountain fire".

4、 The representatives of DIY businesses in the flashlight bar are: eagle eye, woolen pants, pioneers, progressives, night walkers and so on. In fact, some small brands (or small factories with conscience and pursuit) have the advantages of high cost performance; 5. Relatively stable quality and good after-sales service, but the disadvantages are detailed workmanship and circuit efficiency. The after-sales policy is not as good as that of the second brand. Hereinafter referred to as "DIY"

5、 The fifth is jiuliang + Kangming + accord, which has a large sales volume in supermarkets and general markets.

It's a kind of LED flashlight with low price and average quality, but it can be charged directly. The advantages are: cheap, easy to buy; disadvantages are poor workmanship, low brightness, small battery capacity, easy to damage (mostly plastic shell) and so on.

With the five major categories finished, my friends must have a bottom in mind, and choose a brand category according to their own budget. Personal advice is: DIY and cheap brand tube, brand tube also has relatively cheap.

The second part: the simple structure and general classification of the flashlight. The complicated structure and the profile are not included. The simple understanding is four parts: the shell (acting as part of the wire, including the switch), LED / lamp bead, circuit, battery. The simplest circuit diagram, learning junior high school physics should know. No matter how complicated a flashlight is, it can be divided into four parts!!! I'd like to edit it briefly: now we mainly discuss three items. Let me talk about them separately. 1、 Shell, evaluation shell good or not, mainly depends on three aspects: first, solid materials?? Is the barrel thick? And how about the thread treatment? Wait. Second, how about surface oxidation?? Oxidation directly determines the handle!! Third, how about heat dissipation? Which kind of heat conduction chamber?? Time is limited. Let's talk about it briefly. It is obvious that the materials and oxidation are obvious. The stockade goods are not as good as the pioneer C8:

The common circuit warehouses are integrated warehouse, separated warehouse and hollow warehouse. Specific comparison chart is not on, you just need to know one warehouse is basically the best on the line! If you buy a flashlight, you can directly ask the customer service, "are you in one warehouse?" Fill in a picture: Shanzhai and DIY thread, you see, looking forward to the brand tube thread??

2、 Electric circuits related to the flashlight. The pit of the circuit is too big, my circuit is not very good, can only talk about: there is a called current limiting circuit (can not say bad), but the use of constant current circuit is certainly not as effective. The so-called current limiting type is: the battery is full, the flashlight is very bright, 70% of the battery power, the brightness is about 70%, half of the battery power, the brightness may be half, greatly affected by the battery!!! Of course, the cost is also cheap. On the surface, it looks like it has a long endurance (because the circuit is muddy). There is also a circuit called constant current type [8]. I have a Fenix hl23 which I personally tested. This part of the illuminance meter software is very gentle, which is called constant current. The constant current effect of this circuit is good, of course, if it is more expensive brand tube, or small current, then the constant current effect will be better.

In fact, you can't beat them to death with one stick, but the constant current effect is not particularly good, which is between the two. For example, the constant current effect on the left is not very good, and the constant current effect on the right is very good. Because the brightness gradually decreases, sometimes the human eye can adapt, but the constant current circuit is definitely more comfortable to use, isn't it?? And even the constant current circuit has good and bad, so there is a more expensive current limiting driver than the simple constant current circuit 7135. I think we prefer the latter. After all, the brightness is constant for a long time, and the eyes are comfortable, aren't they??


Add: now many brands have started the tailgating design of downshift (downshift); for example, the nominal brightness of 1600 / 800 in 1st / 2nd gear is not constant in the whole process, and the downshift in 1600 gear lasts about 3 minutes (red in the picture), and then it runs continuously with 50% brightness (slow down to 40%), and finally the test ends because the battery voltage is too low; 800 gear (Orange) the effect is slightly better; the gear below 350lm is almost constant current throughout the whole process, so it can be seen that the most suitable brightness of this flashlight should be about 500. This kind of tail endurance design of deliberately improving brightness and adopting downshifting or downshifting can meet the improvement of endurance, but it is not worth promoting for the use experience. The flashlight shown in the figure is Fenix pd36r.


3、 Lamp beads. There are many kinds of lamp beads with different prices. More common is led and light bulb, LED is more practical, and play with the light bulb is more emotional, this time mainly talk about LED. Main manufacturers: ① Cree, originated from the United States, Cree LED is the most common; the figure below shows Cree Led comparison chart (the picture is very old) ② Philips in the Netherlands and OSRAM in Germany rarely use flashlight, but more household lamps and lanterns are used for lighting. ③ Nichia chemical, Nichia's LED has the advantage of high color rendering. ④ supplement on October 31, 2019, a brand of luminus has emerged in the last two years, but its real luminus has existed for a long time, but it is not common before. Recently, many manufacturers are using it The advantage is that the price is cheaper and the color temperature is not as good as Cree.


4、 Finally: how bright is the flashlight? These four aspects determine the brightness of the flashlight. ① The first is the battery, the battery without electricity will not be fully charged (if other parameters are the same); the second is the lamp bead, the LED with high power and high luminous efficiency will be brighter; the third is the driving circuit, which directly affects the current. Which is brighter when 1A current passes through the LED or 2A? ④ Finally is the shell, the finger size flashlight and the bowl mouth thickness flashlight, which is bright??? If it's not bright, it's mostly full.


The second part, the general classification of flashlight

Strictly speaking, there are many kinds of classification of flashlight. What we are talking about today is classification by case (considering batteries at the same time). Personal opinion, according to the size of the shell, the flashlight can be divided into five types: ① big head and long-range, the head of the flashlight is large or thick, generally with multiple batteries; ② medium head, the flashlight is moderate in volume, generally with a lithium battery; ③ small straight, the flashlight is small in volume, which is mainly different from the middle head; ④ AA tube and AAA tube 5 / 7 battery flashlight, smaller than ordinary small straight. 5. Special flashlight, built-in polymer battery, or lamp, headlamp, camp lamp, etc. The Fenix flashlight is used as a reference for the following: first, big head and long shot, which means that the head of the flashlight is large, or the light cup is deep, as you can see from the above picture. Of course, this kind of flashlight is not cheap. The head diameter is more than 60mm. Advantages: high brightness, long endurance (because of many batteries), solid handle (because of heavy weight), self-defense, equipped with sharp tools, and excellent heat dissipation. Disadvantages: expensive, high battery requirements, too heavy to carry. Note: these flashlights are generally called "big killers".


2、 Midhead flashlight,

Generally, the diameter of the head is about 30-50 mm (everyone's opinion is different, for reference only), which can be called the middle head. Let's see the picture. Advantages: moderate size, moderate heat dissipation, moderate brightness, moderate endurance. Disadvantages: the long-range brightness is not as good as the big head, and the floodlight is not as good as the small straight. Generally speaking, it is a better balanced flashlight. It is recommended to start with.

3、 Xiaozhi (18650 Xiaozhi)

Small straight refers to the small head and straight body of some flashlight, simple understanding is: small straight flashlight, on behalf of Fenix uc30, the head is generally about an inch (25.4mm). Advantages: compact and portable, brightness can be comparable with the head, some direct charging flashlight support USB direct charging, power supply is convenient. Disadvantages: the workmanship is not as solid as that of the middle head, and the heat dissipation is not as good as that of the middle head. That is to say, the time of the highest bright grade is not as good as that of the middle head, so it is recommended to start.

4、 Aatube / AAA tube.

AA is a battery, commonly known as No.5 battery, AAA is No.7 battery, a relatively small kind of flashlight, you see: E12 is AA flashlight, about the same size as lighter, also very light. Recommended to send students and family, because the AA cylinder E12 with a plate of millet rainbow battery, enough for more than half a year!!! A plate of millet rainbow is only 9.9, and it can be replaced by rechargeable batteries, which is more cost-effective. Advantages: compact and portable, the battery is a common 5 / 7 battery, easy to buy. Disadvantages: low brightness, short endurance, poor heat dissipation, difficult to work against the head.

5、 Special flashlight,

Including headlights, camp lights, some USB lights, as shown in the figure: advantages: easy to carry, USB direct charging power supply easy to take. Disadvantages: low brightness, short endurance.
