Walk in the wild outdoors, away from the hustle and bustle of the city. In recent years, the outdoors has become the most desirable place for countless people. But outdoor activities often require a lot of equipment, and a flashlight is essential. In the face of dark night and unknown darkness, the choice of outdoor flashlights is also very particular, so let's talk about the selection strategy of outdoor flashlights today.

Many people have a blind spot of knowledge: they think that the brighter the flashlight, the better, but in fact, it still depends on the specific environment. For example, search and thunder search and hunting require high brightness to illuminate far away, diving requires good waterproof performance, and hiking and camping require strong endurance. But no matter what kind of outdoor activities, the choice of flashlight has the following points in common.

1

High hardness barrel

Outdoor bumping happens from time to time. If there is no hard and wear-resistant cylinder, it is easy to be scrapped after only one trip. Therefore, the barrel material is the primary parameter for choosing outdoor lighting tools. Except for the expensive high-strength carbon and titanium alloys, the flashlight bodies currently on the market will be made of aluminum alloy, aluminum-magnesium alloy, ABS engineering resin and other materials. These materials have high-strength, shock-resistant, fall-proof, waterproof and rust-proof characteristics. As for the stainless steel material, rust will occur if it is corroded by moisture for a long time, and it is easy to be oxidized. Once the inside of the cylinder is damp, the battery will short-circuit and leak, which will involve more safety issues.

2

Lightweight and easy to carry

A small, light-weight flashlight can be more favored by outdoor groups. In order to walk outdoors more freely, the weight of the outdoor flashlight should be controlled within 100~200g, and the shape should not be too large.

3

Warm color light source

At present, there are four types of flashlight light sources: LED, incandescent lamp, halogen lamp, and xenon lamp (HID). Among them, LED is widely used. LED has several light color types such as white light (color temperature around 6500K), medium white light (color temperature around 4000K), and warm white light (color temperature below 3000K). Outdoor activities are more inclined to use warm white light, because the color rendering index of low color temperature is relatively high, the higher the color rendering, the warmer the light color, the clearer the details of the object illuminated by the light. Secondly, the color temperature is low, the wavelength is longer, and the penetration is stronger in rainy and foggy weather.

4

High brightness lumens

The outdoor environment is intricate and complicated, and no one knows what kind of situation will be encountered. For example, when exploring unfamiliar roads or in emergencies that require high-brightness lighting, it is fatal if the flashlight is unable to do so. Generally speaking, the maximum brightness of an outdoor flashlight is better than 100 lumens.

5

Multi-speed adjustment

Many people think that the multi-speed flashlight operation is too cumbersome, but the multi-speed design is actually very useful. First, it helps to dissipate heat, and second, you can freely select the brightness mode. When you encounter danger outdoors, you can press the SOS gear tightly, send out the morse code for help, and ask the rescuer for help. When encountering dangerous people or beasts, it can be adjusted to the flash mode to gain the priority of escape or fighting.

Tips for adjusting gears: Because some beasts become more dangerous due to irritability under strong light stimulation, you must be careful when adjusting the brightness!

6

Excellent battery life

As the saying goes, "A flashlight that does not emit light is not a good flashlight." The battery gives the flashlight its inner soul. Common batteries include AA, AAA batteries, 18650 and built-in battery packs. AA and AAA batteries are cheap and can be bought everywhere. The 18650 lithium battery is a rechargeable battery with a small straight barrel shape and strong battery life. If necessary, you can bring a few more sets for the trip.

7

Good waterproof performance

Compared with home, the big problem that flashlights must solve outdoors is waterproof. A good flashlight will come with a waterproof gasket and a waterproof rating above IPX6. Even if it is immersed in shallow water (generally within 2 meters), it can be used normally, and it is even more convenient to fight against violent storms.

Choosing an outdoor flashlight is not that the more expensive the better, but that you should choose the "third eye" that suits you best in combination with the parameters and environment. By the way, it is recommended that you should not use the mobile phone's own flashlight outdoors, because the flashlight of the mobile phone is easy to burn out, and the mobile phone also needs to maintain the power. Maintaining the communication (playing games) is the right choice.

The above tips, I hope they can serve as a little reference when you need to choose a flashlight. I hope anyone who loves outdoor activities can get their own satisfactory flashlight and get a better outdoor experience.
