As a practical outdoor lighting tool, high-intensity flashlights are favored by many people for their characteristics such as high brightness and durability. The following will introduce in detail the relevant knowledge of high-intensity flashlights and answers to some common questions.High-intensity flashlights usually use light-emitting diodes (LEDs) as their light source. The principle of their light emission is that under forward voltage, electrons are injected from the N region into the P region, and holes are injected from the P region into the N region. Some of the minority carriers entering the opposite region recombine with the majority carriers to emit light.
LED high-intensity flashlights are characterized by efficient conversion of electrical energy into light energy. Compared with traditional lamps, they do not generate a lot of heat energy, nor do they cause energy waste, and they will not cause fading of documents, clothes, etc.
Hiking: Hiking generally does not require extremely high brightness, but since it takes a long time, it is better to choose a lighter flashlight with a long battery life. At the same time, it should have a moderate balance between spotlight and floodlight. However, team leaders need flashlights with higher brightness and a certain range to make it more convenient when exploring the terrain.
Camping: For camping, the floodlight effect must be good. The demand for brightness is relatively low, but it is essential to choose an outdoor flashlight with a long battery life, preferably one that can illuminate continuously for a whole night or more. This will be more advantageous in terms of convenience and usage cost.Night riding: Due to the relatively high speed, night riding requires good brightness and a long battery life, preferably capable of continuous lighting for 4 hours. Floodlight is quite important for night riding, while the spotlight part should not be too concentrated. Moreover, night riding flashlights are not sensitive to weight, so you can appropriately choose larger ones, and pay attention to whether they are easy to operate and clamp.
Hunting: High-intensity flashlights used for hunting must have high brightness, and their battery life can be relatively shorter. At the same time, it is better for such flashlights to have impact resistance to avoid damage caused by the recoil of some firearms. The floodlight of such flashlights does not need to be too wide, and the spotlight should be moderate.
Searching: For searching, the brighter the flashlight, the better, and the range is also very important. Weight and size have to take a back seat, so you can choose bright and large flashlights.
Diving: Diving flashlights emphasize absolute waterproofness and reliability, and also have high brightness requirements, while the lighting time is sufficient as long as it is enough. There are no strict requirements on volume and weight; a slightly larger hand-held lamp is better for holding, with good flexibility in use. The switch must be able to withstand water pressure, so it is best to have a hand strap with a locking function to prevent accidental falling off.
Caving: The environment for caving is quite harsh. Due to the low reflectivity of rocks inside caves, the flashlight must have high brightness. The presence of water in caves requires the flashlight to be highly waterproof. Meanwhile, the potential emergencies at any time demand the flashlight to be sturdy and durable, able to withstand impacts from rocks and falls without being damaged.
