What is Flashlight and Headlights?
2024-10-18
  • Main functions of headlights : When we walk at night, if we hold a flashlight, one hand can't be empty. In this way, we can't deal with accidents in time. Therefore, a good headlight is what we should have when we walk at night. When we camp at night, wearing headlights can make our hands free to do more things.

  • Application scope of headlamp, Rechargeable Headlamp
    Outdoor products, suitable for various places. It is essential for us to walk at night and camp outdoors. Headlights may work when you are doing the following:
    Canoeing, holding a climbing stick, looking after the campfire, rummaging through the attic, staring at the depths of your motorcycle engine, reading in your tent, exploring caves, walking at night, running at night, disaster emergency light source.


  • Common light sources of headlights, LED Headlight

    Incandescent lamp, high pressure gas discharge lamp, LED (light emitting diode), hybrid bulb.

    Common Battery
    1. Alkaline batteries are the most commonly used batteries. Its electric energy is higher than that of lead batteries. It cannot be charged. When it is at low temperature 0f, it has only 10% ~ 20% power. When it is used, the voltage will be significantly reduced.
    2. Nickel cadmium batteries: it can be recharged thousands of times and can maintain a certain power. It can't compare with the electric energy stored by alkaline batteries. 0f at low temperature still has 70% power. It's best to carry a high-energy battery during rock climbing, which is 2 ~ 3 times higher than the standard battery.
    3. Lithium battery: it is 2 times higher than the electric energy of ordinary batteries. Two alkaline batteries with an ampere value of a lithium battery more than 2 times / hour are used at 0f as at room temperature, but it is very expensive, and its voltage can be kept constant. Especially useful at high altitudes.


    First class selection skills

    The selection and use of lamps and lanterns and headlights is one of the very important equipment for field survival. "If you want to do well, you must first sharpen your tools", and the correct selection of tools can make it easier for you to deal with in different environments. There are many kinds of headlights. We will have different choices according to different effects.

    The selection of lamps is a troublesome problem. The function, price, weight, volume, versatility and even appearance will affect your final decision. Then start from the most basic needs, and specifically how to select specific lamps at a specific time and in a specific environment.



  • Consider use

    a. If you can't walk at night and don't need to use it to search for water at night, you don't need to use too complex lamps and lanterns just for leisurely dinner in the camp. In this case, the simplest LED lamps are enough. The lighting time is long, the use is economical, convenient and compact. At present, the most popular 25 piece 5LED small head lamp is a cheap choice, All kinds of ordinary small flashlight are also good (but sometimes it's best to DIY a small headband).
    b. If you are often in the wild, you may have the experience of driving up the mountain road in the middle of the night in the rain. In this case, you need an incandescent light source lamp with sufficient brightness, which has good waterproof and reliability, relatively power saving and long range. In short, you need a lamp with good balance. If you want to save some money, the domestic imitation l flashlight and some domestic headlights are OK, but its weight and volume are too big relative to its brightness.
    c. If you plan to do a long-distance donkey trip, you need both sufficient lighting time and necessary lighting brightness. At the same time, lamps with two different types and different batteries may make you depressed. Then, dual light source lamps are your best choice.



  • Consider the environment in which it is used

    The special equirements for lamps in ordinary outdoor environment are not very high, but in some special environments, we must suit the remedy to the case.

    A. Winter

    The battery performance is greatly reduced at low temperature. Unless you have the strength to carry enough spare batteries, it is the best choice in northern winter or snowy mountain environment. It is best to have a dual light source lamp with an external battery box. You must pay attention to that the operation of the headlamp can be easily completed with thick gloves.

    B. Diving

    Submersible lamps emphasize absolute waterproof and reliability, sufficient lighting time and high brightness requirements, and it is best to have standby bulbs that can be used immediately. The requirements for volume and weight are not very strict, and the use flexibility of handheld lamps is good.

    C. Exploratory cave

    The environment of the exploratory cave is more dangerous. Running water and falling rocks require that the headlamp must have the characteristics of firmness and waterproof. Of course, it should also be easily combined with the helmet. The calcium carbide lamp used for long-term exploratory cave will not be explored here for the time being. High brightness is necessary. In order to deal with the unimaginable dilemma caused by the sudden extinction of the bulb in the process and turn on the second light source in time and conveniently, the dual light source lamp is the most appropriate, and the range of the LED is obviously not enough, then the head lamp of the dual lamp bowl and dual halogen bulb has a place to play.

    D. Search

    If it is used for outdoor rescue and search, there is no doubt that brightness and range are in the first place, then two sacrifices will usually be made: sacrificing weight and volume. Or sacrifice the life of the bulb for brightness, and sacrifice the continuous use time for compact volume.
