Do you use the kind of flashlight for outdoor sports?
In outdoor activities such as hiking through the fields, we inevitably have to walk in poorly lit areas. Therefore, the importance of lighting at night, and sometimes it is related to life safety. So having a good outdoor lighting device is very important. Almost all outdoor sports participants who need night activities will give themselves a flashlight to use. However, you can find out carefully that some people choose flashlights that are large and bright and scary, while others have more compact flashlights. . What is the difference between them?
What's the difference between outdoor flashlights?
Hiking and camping
Walking does not require too high brightness, due to a long time, you can try to select a lighter flashlight, while having a longer battery life. Under normal circumstances, flashlights need to balance moderate light gathering and floodlighting. Therefore, it is best to use a hiking flashlight with a weight of about 100g, and the battery life is several hours.

The use of flashlights for camping must be better, and the demand for brightness is low, but it is necessary to choose flashlights with long battery life. The card has sufficient brightness and long battery life. It is best to have a flashlight with a low profile that can reach tens of hours or more in order to prepare for continuous lighting for more than a week in extreme cases.
The first problem to be solved in the outdoors is waterproofing. The reassuring standard for waterproofing is of course IPX-8. This level of waterproofing protects the rain and soaks no more than 2 meters. However, this waterproof performance is a joke when diving.
Diving and caving
The diving flashlight emphasizes absolute waterproofness and reliability, and the brightness requirement is also very high. The lighting time is enough. The switch must be resistant to water pressure. In addition, it is preferable to have a locking hand strap to prevent accidental removal. The environment corresponding to the cavern is rather treacherous, and the rock reflection inside the cave is low, so the brightness must be high! There is water in the cave, and the flashlight is generally required to have good waterproof properties. At the same time, the flashlight may require strong and durable flashlight. Can withstand the impact and fall of the stone without damage.
EDC (Every Day Carry)
This kind of flashlight is generally a miniature spare flashlight. It must be small and light so that it can be carried around at any time. When some emergencies occur, it is often the type of flashlight that you carry with you that can save you a life. EDC flashlight due to power supply volume restrictions, the general brightness will be lower, some with a gear adjustment flashlight, battery life will be very long, the function will not be too much.

What kind of outdoor flashlight?
If you understand the characteristics of flashlights required in various outdoor sports above, then the specific choice of flashlight is the next step. As a flashlight, there are two most important parts. One is a light bulb and the other is a battery. The two complement each other, and the powerful light bulb lighting capability creates a huge power consumption, and the larger power carrying capability also supports the brightness and endurance.
What type of flashlight do you use for outdoor sports?
Current outdoor flashlight bulbs are generally LED, long life, high brightness. Of course, there are also non-LED bulbs, and even halogen lamps, but these are for special purposes or special circumstances. Here we only introduce the LED, LED choose the United States CREE. Divided into a variety of models, the list is as follows:
XRE grades are P3 P4 Q2 Q3 Q4 Q5 R2
XPG grades are R3 R4 R5 S2 S3
XML levels are T4 T5 T6 U2 U3
What type of flashlight do you use for outdoor sports?
The further down, the better. Common on the market are: XRE Q5-WC, XPG R5-1A, XML T6-1B and so on. We recommend choosing R6 or above T6. The most cost-effective. An R5 LED light requires 20 or more yuan for import. Therefore, if you see the entire flashlight on the Internet for less than 30 yuan, forget it.
It is very important that the battery is related to the life and safety of the flashlight. Remember, unless you really understand the truth, choose the 18650 lithium battery. 18650 is the highest density of rechargeable lithium batteries, originally used for laptop batteries. Small size, light weight, wide range of uses, cheap (about thirty dollars).
