Instructions for purchasing outdoor lighting tools
First, the choice of outdoor flashlight - from the perspective of outdoor flashlight performance
1, high reliability
The requirement for lighting tools for outdoor sports is “ready to use”. Unreliable lighting tools that are not working at critical moments are fatal and can be life-threatening. Therefore, high reliability is the most important principle for choosing outdoor flashlights.
2, good waterproof performance
Relative to the home, the first problem to be solved outdoors is waterproof. The reassuring waterproof standard is of course IPX-8. The outdoor flashlight is immersed in shallow water (generally within 2 meters) and can be used normally. Of course, it is not against rain. Under the circumstance, in a sense, waterproof is also the content of outdoor reliability.
3, good life
It is impossible to carry a large number of batteries for outdoor activities, so try to use high-efficiency outdoor flashlights to ensure sufficient brightness and long battery life. It is best to have a low-light flashlight that can reach tens of hours or more in order to be able to illuminate every night for more than a week in extreme cases.
4, high brightness
The outdoor activities are complex, and no one can guarantee what kind of situation you will face. When high-intensity lighting is required, it is dangerous to have a flashlight.
Therefore, a high-brightness outdoor flashlight is an essential lighting tool, especially for the exploration of unfamiliar road sections. The maximum brightness of outdoor flashlights is preferably more than 100 lumens.
5, small and light
Outdoor flashlight should be as small as possible and light in weight. It does not increase the load and saves physical strength. The general personal outdoor flashlight is preferably controlled within 100g. Of course, a powerful outdoor flashlight requires more expense in terms of weight and size.
6, multiple file dimming
You can choose the most appropriate brightness for different purposes such as camping, hiking, search, etc., while saving valuable electrical energy. At the same time, multi-level dimming technology has also derived a number of auxiliary functions, such as SOS distress signal, when the danger is met, you can send a Moss password to ask for help. In addition, there is a strobe function. When you encounter an emergency, a beast or a person who is not bad, turn on the strobe function in time to make the other person's eyes suddenly blind, then you can take the opportunity to escape.
7, constant brightness
While working outdoors, the battery is getting lower and lower with the energy consumption. The brightness of the traditional flashlight is also reduced, and the lighting effect is gradually worsened. When the brightness of the flash is reduced to a certain level, it is unable to provide suitable illumination. The battery is replaced, and at this time, the battery is still half as small as the battery, so this part of the power is wasted.
The emergence of the latest constant current circuit technology solves this problem. The lighting tool using this technology can maintain the brightness in the actual use, providing a more comfortable lighting experience, and the power consumption is more effective.
8, the battery is easy to obtain
Outdoor flashlights are best used in batteries that can be purchased all over the world, even in small mountain stores. In most cases, the ideal battery with this feature is the AA battery. However, considering the battery capacity of the AA battery is small, a large-capacity rechargeable lithium-ion battery (18650 battery) and a cold-resistant disposable lithium battery (CR123A battery) are also recommended batteries.
Second, the choice of outdoor flashlight - according to the use of choice
1, on foot
You don't need too much brightness on foot. Because of the long time, you can choose a lighter flashlight and have a longer battery life. Under normal circumstances, outdoor flashlights need to balance moderate spotlights and floodlights. However, the team leader still needs a higher brightness flashlight and has a certain range, which is more convenient when exploring the terrain.
Floodlight must be good, low brightness demand, but need to choose outdoor flashlight with long battery life, it is best to continuously illuminate all night, such outdoor flashlight has advantages in convenience and cost of use.
3, night riding
Because of its high speed, it requires good brightness and high requirements for battery life. It is best to continuously illuminate for 4 hours. Floodlight is very important for night riding, and the concentrated part should not be too concentrated. Night riding flashlights are not very sensitive to weight, so to meet performance requirements, you can choose a larger flashlight, pay attention to whether it is convenient for operation and easy to install on the handlebar.
To ride the flashlight at night, be sure to choose an outdoor flashlight that is not easy to jump. Otherwise, you can choose a flashlight that does not dim in a single gear. Because in the violent bumps, the flashlight jumps, it will bring unpredictable serious consequences!
The demand for brightness is almost as bright as possible, and the range is equally important. The weight and volume have to be considered next. You can choose a bright and large outdoor flashlight.
5, caving holes
The environment corresponding to the cave is more sinister, and the rock reflectivity in the cave is low, so the brightness of the outdoor flashlight must be high! There is water in the hole, and the outdoor flashlight is generally required to have good waterproof characteristics. At the same time, the dangerous situation of the hand should be strong and durable, and it can withstand the impact and fall of the stone without being damaged.
EDC is the abbreviation of Every Day Carry, which means carrying a flashlight with you. Such outdoor flashlights are generally micro-standby flashlights, which must be small and light so that they can be used at any time. In the event of an emergency, it is often the kind of flashlight that can be carried around you to save your life. Due to the limitation of the power supply volume, the EDC flashlight will generally have a lower brightness. Some flashlights with gear adjustment will have a long battery life and will not function too much.
Third, the choice of outdoor headlights
Headlamps, as the name implies, are lights that are worn on the head and are the lighting tools that free the hands. In many respects, the selection criteria for headlights are similar to those of a flashlight. The following three additional important performance indicators for the supplemental headlights:
It is inevitable to encounter rainy days when camping on outdoor camping or other nighttime work, so the headlights must be waterproof. Otherwise, rain or water immersion will cause short circuit of the circuit to cause extinction or light and darkness, posing a safety hazard in the dark. Then you must see if there is a waterproof logo when purchasing the headlights. Generally, if the waterproof level of the headlights is IPX-6, it is enough for normal outdoor activities.
2, resistance to fall
A good performance headlamp must have resistance to impact (impact resistance). The general test method is that the height of 1 meter is free to fall without damage. In outdoor sports, it may also fall due to various reasons such as wearing loose. If the battery is broken or the internal circuit is broken due to falling, it is a terrible thing to look for the battery to fall off in the dark. Therefore, such a headlight is definitely not safe, so you should watch it when you purchase it. Whether there is an anti-fall mark.
3, cold resistance
Mainly for the outdoor activities in the northern region and high altitude areas, especially the headlights of the split battery box. If the headlights of inferior PVC wires are used, it is very likely that the wire skin is hard and brittle due to the cold, causing The internal core is broken, so if you want to use the outdoor headlights at low temperatures, you must pay more attention to the cold-resistant design of the product.
Fourth, the choice of outdoor headlights - consider the environment used
The special requirements for lamps in ordinary outdoor environments are not very high, but in some special circumstances, we must prescribe the right medicine.
1. Alpine environment
At low temperatures, the performance of the battery is greatly reduced. In the winter or snowy environment, it is better to have a dual-source headlight with an external battery box. It must be noted that the operation of the headlight can be easily performed in the case of wearing thick gloves.
2, caving holes
The environment that the cavern responds to is more sinister. The headlights, such as running water and falling rocks, must have the characteristics of strong waterproofing. Of course, it is also convenient to be combined with the helmet. High brightness is a must. In order to deal with the unimaginable dilemma caused by the sudden extinction of the headlights in the process, it is convenient to turn on the second light source in time. The dual-light source lamps are most suitable. At the same time, the range of the headlights is also very important.
If it is used for outdoor rescue, search and use, no doubt the brightness, range is in the first place, then usually two choices of sacrifice, sacrifice weight and volume.
