I often hear that my travel companions get lost and trapped in the wilderness because they have prepared food and water, warm clothes, etc., before setting off but have ignored the lights. As one of the emergency equipment, the "headlamp" should be placed in the backpack. So for the selection of emergency equipment headlamps, is the highest lumen (lumen/lm) the best? In fact, this is not the case. We should refer to some numbers to gauge which one is best for our purpose.
Why are headlamps preferred for hiking at night instead of flashlights? The reason is simple, free your hands to use tools, or use your hands to support your body, climbing and groping in an emergency. Headlamps can allow you to keep maneuvering on the mountain, but when many people choose headlamps, they will immediately pay attention to the lumen (lumen/lm) marked on the headlamps. The higher the lumens, the greater the brightness power of the headlamps and the higher the visibility.
In fact, the light transmittance of headlamps is by no means the only measure of good or bad. The brightness of the light is undoubtedly beneficial, but in fact, the lumen of the headlamp and the durability of the battery affect each other, and different environments and uses have different selection criteria.
Understand, if a user chooses a headlamp of more than 200 lumens in the camp, but it can only last for 2 hours, what about the long night? And if you run the mountain in the middle of the night, choose a headlamp that lasts more than 24 hours but only has about 50 lumens. The light path was not enough to judge the sudden situation, but he fell down but failed to complete the remaining distance. It can be seen that when choosing a car light, which position is suitable can only be considered according to factors such as personal itinerary and purpose, but we can still refer to some numbers to judge which position is the most suitable.
Today we first talk about the difference between lumens. In simple terms, we can be divided into 100 lumens or less, 100 to 250 lumens and 250 lumens or more. For headlamps below 100 lumens, due to the low energy consumption, the backup battery time is usually longer, but the illumination range is not enough and can only illuminate the soles of the feet. For group camping or mountaineering, as well as emergency equipment, this luminosity is sufficient, and there is no need to worry about the radiation intensity that will harm other people's eyes.
100 to 250 lumens, the luminosity is still limited, but if you walk the night mountain alone, walk slowly, and have time to judge what is in front of you slowly is still enough.
100 to 250 lumens, the disadvantage is that the weight and volume will increase, and the luminosity will increase, but it is still limited. As a camping light, it may be a bit dazzling, but if you need more complex activities such as cooking in the camp, it doesn't matter how bright the light is. At this time, pay more attention to the battery consumption time and whether it can meet travel needs.
Finally, the headlamp is more than 250 lumens. The larger the headlamp, the greater the power consumption and the more expensive the price. If it is used for mountain running, mountain biking, etc., it needs to be fast and fully grasps the surrounding environment. Headlamps of 250 lumens or higher are required. It is related to issues such as athletic performance and safety. High-power headlamps consume more power, so you need to prepare a lower lumen but more durable headlamp for emergency use.
The above is the introduction about the difference between headlamp lumens. Do you know how to choose the headlamp that suits you?
