Flashlight is a portable lighting device widely used by people nowadays.
As a flashlight, it is not only a tool, but also a hobby. Nowadays, there are many kinds of flashlights on the market. The flashlights of different brands and models make people feel dazzling. And in this article, Huasourcing will helps you to choose best flashlights for your market needs. Let’s take a look at the common sense about flashlights.
In terms of volume, we can divide flashlights into the following three kinds:
Small straight tube flashlight, characterized by small and delicate, and easy to use.
The middle head is a flashlight of medium head size, which is also the most popular flashlight at present, with strong comprehensive performance.
The big ones are bigger and more powerful. From the perspective of light source, we can roughly divide them into incandescent lamp, LED and HID.
Among them, LED light is the mainstream light source at present, which has the characteristics of small size, low energy consumption and high brightness. Many flashlights use LED light in order to improve the brightness or range. There are various types of flashlight batteries. From the perspective of economic and environmental protection, we do recommend rechargeable batteries.
Choose the type of flashlight according to specific application:
1. Hiking : hiking generally does not need too high brightness. Since the walking will be longer, you can try to choose a lighter flashlight, at the same time with a longer duration. In general, the flashlight needs to balance moderate spotlights and floodlights. However, the team leader still needs a higher brightness flashlight and has a certain range. It is more convenient when exploring terrain.
2. Camping : floodlight must be good. Camping has low demand for brightness, but we must choose the outdoor flashlight with long battery life, preferably continuous lighting for more than one night, such flashlight has advantages in convenience and cost.
3. Night riding : because of its fast speed, it needs good brightness and high endurance. It is better to achieve continuous lighting for 4 hours. Floodlight is more important for night riding, and the focusing part is not too convergence. Night riding flashlights are not sensitive to weight, so in order to meet the performance requirements. You can choose a larger flashlight and pay attention to whether it is convenient for operation and clamping.
4. Hunting : the brightness must be high, the duration can be relatively short, at the same time, the flashlight had better have anti-impact characteristics, so as not to be part of the recoil of the gun impact damage. This kind of flashlight need not be too wide, focusing light is moderate.
5. Searching : the brighter the better, range is also very important. You can put the weight and in the second consideration, you can choose a bright and large flashlight.
6. Diving : diving flashlight emphasizes absolute waterproof and reliability. Brightness requirements are also high, and lighting times need to be good enough (depending on the type of diving you do). The requirement to volume and weight is not harsh, the handheld light fixture should be a bit bigger which is good for holding. The flexibility of usage should be good. The switch should be able to resist water pressure (push button switches are usually not able to resist water pressure, and diving flashlights are usually for rotating or toggling the switch). Therefore, it is best to have an anti-release hand rope with locking function to prevent accidental shedding.
7. Caving: the environment that the cavern responds to is more sinister, and the rock reflectivity in the cave is low, so the brightness must be high! The water in the cave requires the flashlight to have good waterproof characteristics. At the same time, the possible crisis situation requires the flashlight to be strong and durable, and it can resist the impact and fall of the stone.
8 tips for buying an LED flashlight
1. The number of heads : the number of heads should be moderate. Households generally do not need more than 12 heads. Batteries in 2-3 sections would be good, but for other special needs , you can select be according to your own needs. Of course, high power LED flashlights generally cannot reach the number of 12 heads.
2. Welding : welding must be firm. Each diode is welded to the circuit board, if there is a poor virtual welding contact, it may cause the bead is not bright or affect the overall use.
3. Battery : there are two kinds of ordinary batteries and lithium batteries, although lithium batteries are rechargeable batteries, but the life is low, about 2 years. The life of the LED is about 10 years, which you can select according to the actual situation.
4. Brightness : good LED flashlight has high brightness and slow attenuation speed.
5. Light bulb : It is difficult for the naked eye to distinguish the good or bad light bulb when it is extinguished. You can see the consistency of the bulb when it is lit.
6. Waterproof : Good LED flashlight has waterproof function, good anti-seismic performance, that is, resistant to falling. As it is an electronic product, there is a circuit board in the front of the flashlight, which is prone to short-circuit and damage once water enters.
7. The aperture : good LED flashlight aperture is a uniform circle, poor LED flashlight light spots include yellow and blue uneven distribution. Beads should be concentrated as much as possible. This kind of flashlight is unlike ordinary flashlight that can adjust the focal length. Should pay attention not to have astigmatism problem when buying.
8. Appearance : aluminum shell is optional
In a word, we can learn how to choose best flashlights by dividing flashlight structure into luminous body, battery, switch. So when choosing flashlight, you can choose according to different characteristics of the suitable products, at the same time, it is important to note, flashlights and other products also have different rating points.
many people may feel that spending a few dollars or a few hundred dollars to buy a flashlight would get the same brightness. Then what’s the point of spending more money? Just like we never judge cars by their speed, good products should be measured in all aspects.
