Headlamp lighting is to liberate the freedom of hands, but also to achieve the purpose of lighting. What is the role of the headlamp, the application of those places, the use of the headlamp need to pay attention to what matters, please see Xiaobian below.

First, the main role of the headlamp
When we walk at night, if we hold a flashlight, one hand will not be free, so that we can’t deal with the unexpected situation in time. So. A good headlamp is what we should have when we walk at night. By the same token, when we camp at night, wearing a headlamp frees up our hands to do more.
Two, the application of headlamp
Headlamp is an indispensable equipment in outdoor activities, such as hiking at night, camping at night, although some people say that the effect of the flashlight and the headlamp is about the same, but the new headlamp using energy-saving technology, such as LED cold light technology, and high-grade headlamp lamp cup material innovation, are not comparable to the civilian price of the flashlight, so that the headlamp can replace the flashlight, A flashlight is no substitute for a headlamp.

Three, headlamp use precautions
1. Headlamps or flashlights are very important equipment, but the battery must be taken out when not in use to avoid corrosion.
2. A few head lamps waterproof or even waterproof, if you think waterproof is very important to buy such waterproof bulbs but it is best to rain proof, because in the field weather is not their own can manipulate;
3. The lamp holder should have a comfortable cushion, some are like a pen hanging next to the ear;
4 lamp holder switch must be durable, do not appear in the backpack will open a waste of energy or some situation, lamp holder switch design is best a groove, if you think there will be problems in the process of use the best cloth close, take out the bulb or take out the battery;
5. Bulbs do not last long, so it is best to carry a spare bulb with you. Bulbs such as halogen krypton argon will generate heat and be brighter than vacuumbulb, although they will be higher in use and shorten battery life. Most bulbs will be marked at the bottom, while the typical battery life is 4 amps/hour. It is equal to 8 hours of 0.5 amp light bulb.
6. When buying, it is best to try the lamp in a dark place. The light should be white, the light should be concentrated well, or the one that can adjust the light.

7. A method of testing LED: generally installed three batteries, first installed two batteries, the third section with a key short uniform lasting (compared to the headlamp without booster circuit), and lighting time is relatively long (brand [AA] battery about 30 hours), as a camp lamp (refers to in the tent) is ideal; The drawback of the headlamp with booster circuit is that it has poor waterproof performance (most of them are not waterproof).
6, if it is night mountaineering, it is best to use the bulb of the kind of headlamp main light source is ideal, because its light effective distance is at least 10 meters (2 batteries 5), and there are 6~7 hours of normal brightness, and most of them can be rain proof, and bring two spare batteries a night do not have to worry about (don’t forget to bring a spare flashlight, When changing a battery).
