Instructions for purchasing outdoor lighting tools

 1. The choice of outdoor flashlight-considering the performance of outdoor flashlight

  1, high reliability

   Outdoor sports requires lighting tools to be "ready to use". Lighting tools with poor reliability are fatal if they fail to work at critical moments, and the most serious may lead to life-threatening. Therefore, high reliability is the most important principle for choosing an outdoor flashlight.

  2, good waterproof performance

Relative to home, the first problem to be solved outdoors is waterproofing. Of course, the reassuring waterproof standard is IPX-8. Outdoor flashlights can be used normally if they are immersed in shallow water (generally within 2 meters). Of course, they can resist rain. Down, in a sense, waterproofing is also a content of outdoor reliability.

  3, good battery life

   It is impossible to carry a large number of batteries for outdoor activities, so it is necessary to use high-efficiency outdoor flashlights to ensure sufficient brightness and long battery life. It is best to have a flashlight with a low brightness level that can reach more than tens of hours, so that in extreme cases, it can continuously illuminate for more than a week every night.

  4, high brightness

   The environment for outdoor activities is complicated, and no one can guarantee what kind of situation you will face. When high-brightness lighting is required, it is very dangerous for a flashlight to be inadequate.

   Therefore, a high-brightness outdoor flashlight is an indispensable lighting tool, especially for exploring unfamiliar road sections. The maximum brightness of the outdoor flashlight is preferably more than 100 lumens.

  5, small and light

   Outdoor flashlights should be as small as possible and light in weight. It should be carried out without increasing the load and save energy. It is best to control personal outdoor flashlights within 100g. Of course, powerful outdoor flashlights need to be more expensive in weight and volume.

  6, multi-level dimming

  You can choose the most suitable brightness for different purposes such as camping, hiking, searching, etc., while reasonably saving valuable electricity. At the same time, the multi-speed dimming technology also derives many auxiliary functions, such as the SOS distress signal, which can send out the Distress Morse code when encountering danger, and ask for help from search and rescue personnel. In addition, there is a flashing function. When you encounter an emergency, a beast or a person with good intentions, you can turn on the flashing function in time to make the opponent's eyes temporarily blind, so you can take this opportunity to escape.

  7, constant brightness

While the outdoor flashlight is working, as the energy consumption voltage of the battery decreases, the brightness of the traditional 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. Replace the battery. At this time, the battery often has half the power, so this part of the power is wasted.

   The emergence of the latest constant current circuit technology has solved this problem. The lighting tools using this technology can maintain the same brightness in actual use, provide a more comfortable lighting experience, and use electricity more effectively.

   8. The battery is easy to get

  Outdoor flashlights are best to use batteries that can be purchased in small village shops around the world. In most cases, the ideal battery with this characteristic is an AA battery. However, considering the small battery capacity of AA batteries, large-capacity rechargeable lithium-ion batteries (18650 batteries) and cold-resistant disposable lithium batteries (CR123A batteries) are also recommended batteries.

   Second, the choice of outdoor flashlight-according to the use of choice

  1, on foot

   Hiking does not need too high brightness. Due to the longer time, you can choose a lighter flashlight as much as possible, and at the same time have a longer battery life. In general, outdoor flashlights need to take into account moderate concentrating and flooding. However, the team leader still needs a brighter flashlight with a certain range, which is more convenient when exploring terrain.

  2, camping

   The floodlight must be good, and the need for brightness is low, but you need to choose an outdoor flashlight with a long battery life. It is best to continuously illuminate more than the night. Such outdoor flashlights have advantages in convenience and cost of use.

  3, night ride

  Because of the fast speed, it needs good brightness, and also has higher requirements for battery life. It is best to keep lighting for 4 hours. Floodlight is very important for night riding, and the light-focusing part should not be too concentrated. Night riding flashlights are not very sensitive to weight, so in order to meet performance requirements, you can choose a larger flashlight, and pay more attention to whether it is easy to operate and whether it is easy to install on the handlebar.

   For night riding flashlights, you must choose an outdoor flashlight that is not easy to skip gears, otherwise you would rather choose a single-speed non-dimming flashlight. Because in the violent bumps, flashlight jumps, it will bring unpredictable serious consequences!

   4. Search

   The need for brightness is almost as bright as possible. Range is also important. Weight and volume have to be considered second, and bright and large outdoor flashlights can be chosen.

   5. Cavern

The environment corresponding to the    cavern is relatively dangerous, and the rock in the cave has low reflectivity, so the brightness of the outdoor flashlight must be high! There is water in the cave. Generally, outdoor flashlights are required to have good waterproof characteristics. At the same time, possible dangerous situations require the flashlights to be sturdy and durable, withstand the impact and fall of stones without being damaged.

  6, EDC

   EDC is the abbreviation of Every Day Carry, which means to carry a flashlight with you. Such outdoor flashlights are generally miniature backup flashlights, which must be small and light so that they can be carried and used at any time. In some emergencies, it is often this kind of flashlight that you carry around can save your life. Due to the limitation of the power supply volume, the brightness of EDC flashlights is generally lower. Some flashlights with gear adjustment will have a long battery life and not many functions.

   Third, the choice of outdoor headlights

  Headlamp (headlamp), as the name suggests, the lamp worn on the head is a lighting tool that liberates hands. In many aspects, the selection criteria for headlights are similar to flashlights. The following additional three important performance indicators of headlights:

  1, waterproof

  It is inevitable to encounter rain in outdoor camping and hiking or other night operations, so the headlights must be waterproof, otherwise rain or flooding will cause the circuit to short-circuit and cause the circuit to go out or turn on and off, causing safety hazards in the dark. Then you must see if there is a waterproof mark when purchasing a headlight. If the waterproof level of the general headlight is IPX-6, it is enough for normal outdoor activities.

   2. Fall resistance

A headlamp with good performance must have drop resistance (impact resistance). The general test method is to freely fall from a height of 1 meter without any damage. In outdoor sports, it may also slip off due to various reasons such as wearing too loose. If the shell is cracked, the battery falls off or the internal circuit is faulty due to the fall, it is a very terrible thing to find the fallen battery in the dark, so such headlights are definitely not safe, so you should also look at it when buying Check whether there is an anti-fall mark.

  3, cold resistance

Mainly for outdoor activities in northern areas and high-altitude areas, especially headlights with split battery boxes. If the headlights with inferior PVC wires are used, it is likely to cause the wire skin to become hard and brittle due to the cold. The internal core is broken, so if you want to use outdoor headlights at low temperatures, you must pay extra attention to the cold-resistant design of the product.

   Fourth, the choice of outdoor headlights-consider the environment of use

  The special requirements of lamps and lanterns in ordinary outdoor environments are not very high, but in some special environments, we must prescribe the right medicine.

   1. Alpine environment

  Battery performance is greatly reduced under low temperature. In winter or snowy mountain environment, it is best to have a dual-light source headlamp with an external battery box. It must be noted that the operation of the headlamp can be easily completed with thick gloves.

  2, cave

The environment that    caverns deal with is a bit more sinister. Flowing water, falling rocks, etc. require headlights to be strong and waterproof. Of course, it should be easily integrated with a helmet. High brightness is necessary. In order to deal with the unimaginable dilemma caused by the sudden extinguishment of the headlight during the process, and to turn on the second light source in a timely manner, a dual-light source lamp is the most suitable. At the same time, the range of the headlight is also very important.

  3, search

  If it is used for outdoor rescue and search use, there is no doubt that brightness and range are in the first place, so two choices of sacrifice are usually made, sacrificing weight and volume.
