The flashlight itself is used frequently in our daily life, especially the headlight, which is widely used in many applications. The head-mounted headlight is easy to use and liberates the hands to do more things. How to charge the headlight, so we are choosing When buying a good headlight, you need to choose products with different characteristics according to your own use occasions, so do you know about headlights?
What are headlights?
Headlamp, as the name suggests, is a lamp worn on the head, which is a lighting tool for freeing hands. When we are walking at night, if we hold a flashlight, one hand cannot be free, so that we cannot deal with unexpected situations in time. So, a good headlight is what we should have when walking at night. By the same token, when we camp at night, wearing headlights can free up our hands to do more things.
The scope of use of headlights:
Outdoor products, suitable for various places. It is an essential item when we are walking at night and camping outdoors. Headlights may be helpful when you:
Canoeing, trekking poles in hand, tending a campfire, rummaging through attics, peering into the depths of your motorcycle engine, reading in your tent, exploring caves, night walks, night runs, disaster emergency lights. …..
Several kinds of batteries commonly used in headlights
1. Alkaline batteries (Alkaline batteries) are the most commonly used batteries. Its power is higher than that of lead batteries. It cannot be recharged. It only has 10% to 20% power at low temperature 0F, and the Voltage will drop significantly when used.
2. Nickel-cadmium batteries (Nickel-cadmium batteries): can be recharged thousands of times, it can maintain a certain power, it can not be compared with the electric energy stored in alkaline batteries, it still has 70% power at low temperature 0F, rock climbing It is best to carry a high-energy battery during the process, which is 2 to 3 times higher than a standard battery.
3. Lithium battery: It is 2 times higher than the general battery voltage, and the ampere value of a lithium battery is more than 2 times that of two alkaline batteries. It is like using at room temperature at 0F, but it is very expensive, and its voltage can be maintained constant. Especially useful at high altitudes.
There are three important indicators for outdoor protable headlights:
1. Waterproof, it is inevitable to encounter rainy days when camping outdoors, hiking or other night work, so the headlights must be waterproof, otherwise, when it rains or is soaked in water, it will cause a short circuit and cause the circuit to go out or flicker, causing safety hazards in the dark . Then, when purchasing headlights, you must see whether there is a waterproof mark, and it must be greater than the waterproof level of IXP3 or above. The larger the number, the better the waterproof performance (the waterproof level will not be repeated here).
2. Fall resistance. A headlight with good performance must have drop resistance (impact resistance). The general test method is to fall freely from a height of 2 meters without any damage. It may also be caused by wearing it too loosely during outdoor sports. There are many reasons for slipping, if the shell cracks, the battery falls off or the internal circuit fails due to the fall, it is a very scary thing to find the fallen battery in the dark, so such headlights are definitely not safe, so in When purchasing, you should also check whether there is an anti-fall mark, or ask the shopkeeper about the anti-fall performance of the headlight.
3. Cold resistance, mainly for outdoor activities in northern regions and high-altitude areas, especially for headlights with split battery boxes. If you use poor-quality PVC wires for headlights, it is likely that the skin of the wires will become hard due to the cold. It becomes brittle, which causes the internal wire core to break, so if you want to use the outdoor headlight at low temperature, you must pay more attention to the cold-resistant design of the product.
