1. High brightness. Usually, the environment for nighttime travel or adventure activities is complex, and no one can guarantee what kind of situation you will face. Therefore, a high brightness flashlight is a necessary lighting tool, especially for exploring unfamiliar road sections. The maximum brightness of a flashlight is best to exceed 100 lumens. When high brightness lighting is needed, it is very dangerous for a flashlight to be inadequate
2. High reliability. Our requirement for lighting tools is "always available", therefore, high reliability is the most important principle for choosing motion lighting tools. Poor reliability of lighting tools can be fatal if they fail to work at critical moments, and in the most serious case, can lead to life-threatening situations
3. Good waterproof performance. Compared to staying at home, the first issue to be solved when exploring outdoors or outdoors is waterproofing, which is even more important in combating rainy and humid environments. In a sense, waterproofing also belongs to outdoor reliability
4. Compact and lightweight. Outdoor flashlights should be as light in weight, small in size, and carry without increasing the load when going out, saving energy. Generally, it is best to control personal outdoor flashlights within 100 grams. Of course, powerful outdoor flashlights require greater cost in terms of weight and volume
5. Range capability. Try to use high-efficiency flashlights to ensure sufficient brightness and extended battery life. It is best to have a low brightness flashlight that can last for tens of hours or more, in case of extreme circumstances, it can continuously illuminate for more than a week every night
6. Constant brightness. While the flashlight is working, as the energy consumption voltage decreases, the brightness of the regular flashlight also decreases, and the lighting effect gradually deteriorates. When the brightness of the flashlight drops to a certain level, it is no longer possible to provide suitable lighting, and only the battery needs to be replaced. At this time, the battery often has less than half of its capacity, so this amount of power is wasted in vain. The emergence of constant brightness technology has solved this problem. Constant brightness flashlights can ignore changes in battery voltage and provide almost constant brightness for most of the time. This not only improves the lighting effect, but also fully utilizes every minute of battery energy
7. Multi level dimming. Multi level dimming technology, selecting the most suitable brightness for different purposes, while reasonably saving valuable electrical energy. At the same time, multi level dimming technology has also derived many auxiliary functions, such as SOS distress signals, which can send out distress Morse codes to search and rescue personnel in case of danger.
