Tips for choosing headlights

The selection and use of headlights is one of the most important equipment for survival in the wild. "If you want to do a good job, you must first sharpen your tools." The correct choice of tools can make it easier for you to cope with different environments. There are many kinds of headlights, and we will have different choices according to different effects.

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

Consider use

a. If you don't know how to walk at night, and don't use it to search for water at night, you don't need to use too complicated lamps just for a leisurely dinner in the camp. In this case, the simplest LED lamps are enough. The lighting time is long, the use is economical, and the convenience is small. The most popular 25 yuan 5LED small head lamp is a cheap choice, and various ordinary small flashlights are also good (although sometimes it is better to use DIY small head band).

B. If you are often in the wild, you may have the experience of driving on the mountain road in the rain in the middle of the night. In this case, you may have an incandescent light source lamp with sufficient brightness. It has good waterproof and reliability, saves power, and has a long range. In short, you need a lamp with good balance. If you want to save money, the domestic imitation L flashlight and some domestic headlights are not bad, but their weight and volume are too big for their brightness.

c. If you plan to make a long journey, you need not only enough lighting time, but also necessary lighting brightness. At the same time, lamps with two different types and different batteries may make you more depressed. Therefore, dual light source lamps are your best choice.

Environment to be considered

The particularity of lamps in ordinary outdoor environment is 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, the best choice in northern winter or snowy mountain environment is the dual light source lamp with an external battery box. You must pay attention to that the operation of the headlights can be easily completed with thick gloves.

B. Diving

The diving lamp emphasizes absolute waterproof and reliability, sufficient lighting time and high brightness requirements, and it is better to have a spare bulb that can be used immediately. The requirements for volume and weight are not very strict, and the use of hand-held lamps is flexible.

C. Exploratory cave

The environment for exploration is more dangerous. Running water, falling rocks, etc. require that the headlights must be solid and waterproof. Of course, they should also be conveniently combined with helmets. Calcium carbide lamps used for exploration for a long time are not used here for the time being. High brightness is a must. In order to deal with the unimaginable difficulties caused by the sudden extinguishment of the bulb in the process, and to turn on the second light source in a timely and convenient manner, the dual light source lamp is the most appropriate, while the range of the LED is obviously not enough, so the head lamp of the dual lamp bowl and dual Halogen bulb can be used.

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 choices of sacrifice are usually made: sacrifice weight and volume; Or sacrifice the life of the bulb for brightness, and sacrifice the continuous use time for small volume.
