The main common a flashlight, outdoor
1, high reliability
Requirements for outdoor exercise on a lighting tool is "always with", lighting work of poor reliability, unable to work at a critical moment is fatal, the most serious may lead to life-threatening, therefore, high reliability is the most important principle to choose the outdoor lighting tool.
2, good waterproof performance
Relative home, outdoors is the first problem to be solved is waterproof, waterproof standard reassuring the IPX-8 of course, soaking in shallow water (usually two meters) can be used normally, of course against rain would be nothing difficult, in a sense, waterproof also belongs to the outdoor reliability content.
3, compact and lightweight
Outdoor flashlight should as far as possible to the small volume, light weight, portability does not increase the weight, save energy, general personal outdoor flashlight best control in 100 grams, of course, a strong outdoor flashlight to give greater spending on weight and volume.
4, energy saving
Outdoor activities can not carry a lot of battery, so as far as possible to choose efficient flashlight, ensure that there is sufficient brightness and long life time. Had better have a low light file can reach tens of hours to prepare a flashlight, and in extreme cases can continuously for more than a week night lighting.
5, Gao Liangdu
Outdoor environment is complex, there is no guarantee that you will face what kind of situation, the need for high brightness lighting flashlight but ambition is very dangerous, so lighting tools a high brightness of the flashlight is essential, especially in the exploration for not familiar with the road, the highest brightness torch best over 100 lumens.
6, multi gear dimming
Multi speed adjusting light technology, finally the brightness and duration of the fish in the bear's paw in with a torch, you can choose the most suitable brightness in the camp, hike, search for different purposes such as, at the same time reasonably to save valuable energy. At the same time, multiple files dimming technology has led to a number of auxiliary functions, such as S0S rescue signal, danger can send a Moss code, help to search and rescue people
7, the brightness constancy
In the work at the same time, the battery with voltage and energy consumption is low, the brightness of conventional flashlight has also decreased, lighting effect gradually becomes poor, and other electric intensity decreased to a certain extent has been unable to provide proper lighting, only the replacement of the battery, and battery and a half when there is electricity, so this part of electricity is wasted. Brightness constant technology to solve this problem, change the constant bright flashlight can ignore the battery voltage, providing brightness almost constant in most of the time, not only improve the lighting effects, but also makes full use of every minute power battery.
8, the battery is easy to obtain
The best outdoor flashlight can be used all over the world, even small village stores to buy batteries, but also the best battery has good versatility (such as with the camera, GPS radio, you can swap battery). Have this feature in most cases the ideal cell is AA cell.
