Submersible flashlight is a kind of underwater light. The earliest submersible flashlight is only used as a diver, but as people are more interested in the sea, as well as the exploration of underwater ancient articles, National Oceanographic exploration, the latest trend of underwater wedding photography and so on, underwater cameras are widely used on the seabed, thus the development of underwater photography lights is driven by diving. The escalation of the flashlight is a higher demand diving flashlight.

The original diving flashlight was the button switch, then thought of the magnetic ring, and the diving flashlight mostly used toggle switch or rotary switch. The diving depth is basically 30 meters, 60 meters, 100 meters, 150 meters, 200 meters, etc.

Diving can be divided according to different standards. According to the waters, it can be divided into fresh water diving (in inland rivers, lakes, dives) and saltwater diving (dive in the coastal and saltwater lakes), and can be divided into diurnal and nocturnal dives according to the day and night. According to the depth of the diving, it can be divided into shallow dives (less than 30 meters) and deep diving (30-100 meters), according to the location of the diving. Can be divided into field diving and indoor diving!

Different scuba diving demand for submersible flashlight is also different, fresh water diving for the submersible electric power shell slightly weak, because of low corrosion, and fresh water is very clear, so the light is not very high, but the salt water corrosion is very strong, an aluminum alloy diving hand power is very suitable! Of course, the appearance of aluminum alloy must be military regulations, three grade hard oxidation is more corrosion resistant! Strictly speaking, the difference between the night submersible and diurnal submersible is not very big, but the bright scuba dive is more perfect for the night submersible, because at night it is the most active time for the creatures of the seabed, and the plant and the animals play a silent Symphony together! Diurnal potential may feel only general! As for shallow diving, the water repellency and luminance of the scuba dive are not very high, and deep diving requires that the light of the submersible flashlight is farther and brighter, because the danger is bigger and the danger is responsible for life ahead of time. Indoor diving can basically do not require diving flashlight! The best one outdoors!

According to diving purposes, it can be divided into scuba diving lighting flashlight, engineering diving lighting flashlight, fishing lighting flashlight, diving photography flashlight! According to the design mode of diving flashlight, it can be roughly divided into integrated and split diving flashlight. The split type hand lamp is separated from the barrel. It is connected by a specific insulation line. The lamp head can be worn or handheld. It is suitable for different diving occasions and is more flexible and changeable.
