The flashlight has multiple functions that allow the user to operate the buttons efficiently. Today, rechargeable flashlights are loved and welcomed by everyone because they have many new features. There are many factors to consider when shopping for a new flashlight. According to our daily usage scenarios and needs, buy a suitable rechargeable flashlight.

1. Stable performance and high reliability The requirement of outdoor sports for lighting tools is "available at any time and functions can be used". Lighting tools with poor reliability cannot work at critical moments is fatal, and may lead to life-threatening in the most serious cases. Therefore, high reliability is the most important principle for choosing outdoor sports lighting tools. Stable quality and good environmental adaptability are the first things to consider when purchasing outdoor flashlights.

2. Good waterproof performance Compared with ordinary household use, outdoor flashlights need to solve the waterproof problem first. The reassuring waterproof standard is of course IPX-8, which can be used normally when immersed in shallow water (generally within 2 meters). Rain is not a problem, in a sense, waterproofing is also part of outdoor reliability. Outdoor flashlights often have good sealing performance and are protected by multiple waterproof rubber rings to ensure sufficient waterproof capability.

3. Easy to carry Outdoor flashlights should be as easy to carry as possible. Carrying out will not increase the load and save physical strength. General personal outdoor flashlights are best controlled within 100g. The shape of the strong light type outdoor flashlight should not be too large, and the weight is recommended to be controlled within 200 grams.

4. Power saving At present, the strong light flashlight usually uses a rechargeable lithium battery 18650 as the power source, and the continuous lighting time of the strong light is usually 2.5 hours, which requires us to bring backup batteries as needed. At the same time, in the actual use process, an appropriate selection of medium light or low light illumination is beneficial to prolong the lighting time of the flashlight. In addition, you can also consider choosing a flashlight powered by multiple batteries, which will last longer.

5. Multiple gears Many friends who are primary candidates for outdoor flashlights always feel that the operation of multiple gears is too cumbersome. In fact, it is not necessary for the outdoor flashlight to have multiple gears, at least with strong light, weak light, and flashing functions. The single-speed flashlight is not flexible enough, and the flashlight with medium-light or low light can be switched in time, which helps to dissipate heat and prolong the lighting time of the flashlight. It is best to have a flashlight with a low brightness level that can reach more than tens of hours, in order to prepare for continuous lighting every night for more than a week in extreme cases. The emergence of multi-level dimming technology makes brightness and battery life appear on the same flashlight. You can choose the most suitable brightness for different purposes such as camping, hiking, and searching, while reasonably saving precious power. At the same time, the multi-level dimming technology has also derived many auxiliary functions, such as the SOS distress signal, which can send out the Morse code for help in case of danger to ask the rescuers for help.

6. High brightness The outdoor activity environment is complex, and no one can guarantee what kind of situation you will encounter. When high brightness lighting is required, it is very dangerous that the flashlight is not enough. At the same time, the long-range light can also make it easier for others to find it in an emergency. Therefore, a high-brightness flashlight is an essential lighting tool, especially for the exploration of unfamiliar road sections. The highest brightness of the flashlight is preferably more than 200 lumens, and the lighting distance is more than 100 meters.

7. The brightness is constant. While the flashlight is working, the battery voltage becomes lower and lower with the energy consumption, the brightness of the conventional flashlight also decreases, and the lighting effect gradually deteriorates. When the brightness of the flashlight drops to a certain level, it can no longer provide suitable lighting. For lighting, the only way to replace the battery is to replace the battery. At this time, the battery often has half the power, so this part of the power is wasted. The emergence of constant brightness technology solves this problem. The constant brightness flashlight can ignore the change of battery voltage and provide almost constant brightness most of the time, which not only improves the lighting effect but also makes full use of every power of the battery.

8. Batteries are easy to obtain. Outdoor flashlights are the best t use batteries that can be bought in stores all over the world, even in small mountain villages. In most cases, the ideal battery with this characteristic is the AA battery. If you use a battery that is not convenient to buy, prepare enough spare batteries according to the situation before travelling.
