To choose the right LED flashlight for spearfishing or diving, you must first familiarize yourself with the basic parameters of this device.
choose a lantern for divingWhat requirements should it meet? A quality underwater light has the following characteristics:
High water resistance
Reliable robust construction
Long working time
Convenience and ease of use
Battery reliability
In addition, it must be equipped with
Interchangeable reflectors, allowing choice depending on the circumstances
Reliable lace that does not undergo destruction in water
Tactical enable function
The existing IPX8 waterproof standard places quite stringent requirements on diving and spearfishing lights. These devices are checked and tested by repeated immersion. Testing is also carried out in pressure chambers. The data obtained is equally valid for diving in both fresh and seawater. Suitable for use are devices that can withstand immersion to a depth of 30 meters.
The LED flashlight has an undoubted advantage over the xenon flashlight in terms of operating time. If the latter have a limited service life (20-30 hours of operation), then American LEDs have an almost life-long lifespan of 50 thousand hours. If you use a flashlight for 3 hours a day, then it can be used for 40 years. Structural materials that meet American military standards give high strength and reliability to the lanterns.
The lace should be no less reliable. In American lanterns, it is resistant to moisture and has strong mounts so as not to get lost during the dive. It is preferable to choose a metal crab mount. The great advantage of underwater lights is their compatibility with original accessories. Rubber diffusers with different glass colors - green or red - have been developed especially for LED devices. The color is selected depending on the type of fish that they are going to hunt, since some fish do not react to light of a particular shade.
The most convenient type of power supply for flashlights is a rechargeable battery. Usually it is enough for 2 hours at maximum mode. The presence of intermediate brightness modes allows you to increase the operating time up to 10 hours. In these modes, the flashlight provides enough light and can be used continuously.
Underwater lights models
The Armytek Predator underwater torch provides powerful illumination, up to 300 meters in air. This super novelty from the Canadian manufacturer is especially useful for deep diving. Long range, compact optics, functional electronic filling make it indispensable for diving enthusiasts.
More economical, but no less productive, is the Olight T25 underwater LED operating on AA batteries. Air range - 120 meters. The model has an anodized casing and is highly sealed.
Both models are equipped with a tactical turn-on function, which provides convenient control and prevents them from turning off at great depths. Unlike other flashlights, in which the power button is pressed in under the influence of even slight pressure (at a depth of 1.5 - 3 meters), these devices will work flawlessly even when submerged to the maximum possible depth. All controls are optimally accessible in working positions. The ergonomic shape of the handle provides dynamic work of the arm muscles and makes it possible to use the device for a long time without straining.
Choosing the type of lighting
The choice of the type of reflector and diode with a certain shade depends on the purpose of the flashlight. For small dives, it is better to use a flashlight with a wide uniformly luminous beam and good side illumination. In this case, it is better to use a textured reflector. Deep diving requires a long-range and directional light that produces a smooth reflector. The shade of the light depends on the personal preference and needs of the user. A warm diode reproduces colors better and allows you to see fine details. A cold diode will give brighter light, but colors will be lost. For spearfishing, a warm diode is more acceptable, because the fish is frightened by the white bright light and instantly takes off.
