As the name suggests, the headlamp is a light source that can be worn on the head or hat, freeing your hands and illuminating.

Headlights are currently often used in trail running competitions. Whether short distances of 30-50 kilometers or long distance races of 50-100 kilometers, they will be listed as mandatory equipment to carry.

In the call-up posts of outdoor activities, headlights are often listed as essential equipment. The road conditions in the mountainous areas are complicated, and the plan is often not completed within the set time. Especially in winter, the daytime is short and the nights are long. It is also crucial to carry a headlight with you.

So how should you choose your first headlamp?

👉Brightness

Headlights must be "bright" first, and different activities have different requirements for brightness. You can't blindly think that the brighter the better, because artificial light is more or less harmful to the eyes. The unit for measuring brightness is "lumens." The higher the lumens, the brighter the brightness.

If your headlight is used for outdoor trekking, it is recommended to use a headlight between 100 lumens and 500 lumens.

If it is used for caverns and deep into a dangerous environment in complete darkness, it is recommended to use more than 500 lumens. If the weather is bad and there is heavy fog at night, you need a headlight of at least 400 lumens to 800 lumens. If possible, try to use yellow light, the penetrating power will be stronger, and it is not easy to cause diffuse reflection.

👉Headlight battery life

The battery life is mainly related to the power capacity of the headlights. The usual power supplies are divided into two types: replaceable and non-replaceable, and there are also dual power supplies. The non-replaceable power supply is generally a lithium battery rechargeable headlamp. Because the battery shape and structure are compact, the volume is relatively small and the weight is light.

The replaceable headlights generally use No. 5, No. 7 or 18650 batteries, and the ordinary No. 5 and No. 7 batteries must be used with reliable authentic products purchased from regular channels, so that there will be no false standard power or Will cause damage to the circuit.

The 18650 battery is also a kind of battery. The working current is relatively more stable. 18 represents the diameter and 65 is the height. The capacity of this battery is usually very large, basically above 3000mAh, so many headlights that are good at battery life and brightness are all Willing to use this 18650 battery. The disadvantage is that it is bulky, heavy, and slightly expensive. Use caution in low-temperature environments.

For most outdoor lighting products (using LED lamp beads), usually 300mAh power can be used to maintain 100 lumens brightness for 1 hour, that is, if your headlight is 100 lumens and you use a 3000mAh battery, then there is a high probability that it can be bright for 10 hours .

👉Light range

The range of the headlight is commonly known as how far it can shine, that is, the intensity of light. Its unit is candela (cd).

200 candelas have a range of approximately 28 meters, 1000 candelas can have a range of 63 meters, and 4000 candelas can have a range of 126 meters.

200 to 1,000 candela is sufficient for ordinary outdoor activities. For more information, please consult us at any time.

👉Headlight color temperature

Color temperature is a piece of information that we often overlook. Just think that the headlights are bright enough to shine far enough. As everyone knows, there are many kinds of light. Different color temperatures also have an impact on our vision.

The color temperature used for headlights is mainly concentrated in the range of 4000-8000K, which is visually comfortable. The warm white of spotlights is generally about 4000-5500K, while the bright white of floodlights is about 5800-8000K.

👉Weight 

Some people are now very sensitive to the weight of the equipment. There is no special epoch-making product for headlights, and it can maintain continuous navigation while at the same time. The larger capacity must be heavier, and the lighter one must be sacrificed. Therefore, it is very difficult to find a headlight that is light, bright, and has a particularly long battery life.

👉Durability

Headlights are not disposable products. Good headlights can be used for at least ten years, so the durability is also worthy of attention. There are three main aspects:

• One is resistance to fall. We can't avoid bumping the headlight during use and transportation. If the shell material is too thin, it may be damaged after being dropped several times. However, if the circuit board is not welded firmly, it may be directly powered off and not bright after using it several times. Therefore, it is best to choose a headlamp with a long warranty.

• The second is low temperature resistance. The night temperature is often much lower than the daytime temperature, and it is difficult to imitate the extreme low temperature in laboratory tests, so some headlamps will not work well in an extremely cold environment (around -10°C). The root of this problem lies in the battery. Under the same conditions, keeping the battery warm will effectively extend the life of the headlight. If it is predicted that the ambient temperature is very low, it is necessary to bring more spare batteries.

• The third is corrosion resistance. If the circuit board is stored in a humid environment, it is easy to mold and grow hair. If the battery is not taken out from the headlight in time, the battery will leak and corrode the circuit board. This requires us to carefully maintain the headlight every time we use it, remove the battery in time, and dry the wetted components as soon as possible.
