How to choose a diving flashlight?

We often use flashlights when diving, so how do we choose the right flashlight? Don't choose at random. Today, Bian Xiao will arrange information about diving flashlights for you. If you still don't know, you can find out!

Classification of diving flashlights 0 1. The classification of waters can be divided according to different diving standards! Different diving requires different diving flashlights.

Fresh water diving has a slightly weaker requirement for the shell of diving flashlight, because the corrosiveness is low and the fresh water is very clear, so the lumen requirement for light is not very high.

Salt water is very corrosive, and aluminum alloy diving flashlight is very suitable. Of course, if military regulations and three-stage hard oxidation are needed, the appearance of aluminum alloy is more corrosion-resistant.

Strictly speaking, there is not much difference between night diving and day diving, but a bright diving flashlight is more suitable for night diving, because at night, when underwater creatures are most active, plants and animals play a silent symphony together!

Thanksgiving may feel ordinary! As for shallow diving, the waterproof and brightness requirements of diving flashlights are not very high.

Moreover, deep diving needs a flashlight to shine farther and brighter, because the danger is greater, and predicting the danger in advance is responsible for life!

There is basically no need for diving flashlights for indoor diving, so it is best to prepare one outdoors.

03. Usage classification According to diving usage, it can be divided into scuba diving lighting flashlight, engineering diving lighting flashlight, fishing lighting flashlight and diving photography flashlight.

04. Style classification According to the design mode of diving flashlight, it can also be roughly divided into integrated and split diving flashlight.

The lamp holder of the split flashlight is separated from the cylinder and connected by a specific insulating wire. The lamp holder can be worn or held by hand, which is suitable for different diving occasions and is more flexible to use.

For example, DIV09 and DIV 10 of luminous Brintye are split designs, which can not only meet the needs of leisure diving, but also be competent for technical diving occasions such as cave diving.

Performance analysis of accessories 0 1. Magnetic switch of diving flashlight switch: The switch port pressure is limited, which is easy to be infiltrated by seawater impurities, and some sealing aprons are even easy to be corroded, so the diving depth is generally less than 30 meters, and the service life is very limited.

Rotary switch: strictly speaking, it is equivalent to basically eliminating the fatal weakness of switch opening without switch. Widely used in high-end deep waterproof diving flashlight, the waterproof depth is above 100 meters.

02. CREE series led of flashlight light source is widely used, especially Q5/R5/T6/SWC 100W. Lumen is the unit of light, and 100 lumen is approximately equal to 1W high power.

CREEQ5, the brightness can only reach below 230 lumens; CREER5, the brightness can reach about 350 lumens; CREET6, brightness up to 1000 lumens; SWC 100W, and the brightness can reach 10000 lumens.

03. Batteries used in flashlights Different types of batteries have an impact on the brightness and battery life of flashlights, and different numbers of the same batteries also have a great relationship.

04. Gun barrel material Plastic gun barrel: it is light in weight and flexible to use, but it is easy to age and be corroded by seawater over a long period of time. If it is accidentally dropped on land, the gun barrel is likely to be scrapped and not durable.

Aluminum alloy barrel: slightly heavier than plastic barrel, slightly less flexible, but very corrosion-resistant and impact-resistant! The price is also much more expensive. The high-end brand aluminum alloy diving flashlight 1.5 meters can fall freely, and the appearance of military regulations is difficult to oxidize!

05. Flashlight lens glass lens: good light transmission, but not impact-resistant, so be especially careful when using it!

Acrylic lens: poor light transmission, better impact resistance than glass, not an ideal material!

Bullet-proof PC lens: good light transmission, and very impact-resistant, hammer can not break! But the price is expensive, and the cost of flashlight increases. It is indeed the most ideal diving flashlight lens!

Misunderstanding 1: The higher the brightness of strong light, the better. The first method is: the flashlight should trudge in the bright light, from the lamp holder to the reflective bowl, battery, motherboard plane and so on. International and domestic brand-name goods have undergone strict planning and inspection to ensure service life and safety.

The second method is: choose to remove the battery maintenance board and finish it by increasing the voltage and current: overclocking.

Therefore, a flashlight distributed at 100 yuan is marked with 3000 lumens or even higher, resulting in unlimited heat. Because of the mismatch between the two, the repeatedly burned lamp holder and lithium battery often discharge excessively. From light to light, it can only be repaired for a few minutes, and from heavy to high fever, it will cause a fire.

Myth 2: Misguided by false parameters, many sellers intentionally or unintentionally mark the virtual lumen value. Goods that originally needed only a few hundred lumens were forcibly marked with 2000 or even higher.

In terms of power, regardless of common sense, false signs such as 10W 12W or even higher often appear. The material aspect is even more ironic. Slogans with China characteristics, such as the brightest lamp caps imported from foreign countries, are endless.

Ok, let's collect this information, and pay attention when choosing a diving flashlight!
