Flashlight Rechargeable LED: specifications, prices

A flashlight is a necessary device in any household. The need to illuminate the dark space can also arise during the movement along the street at night, and when performing repair work in hard-to-reach corners. There are also specialized modifications designed for mining workers, tourists, emergency service employees, etc. On the market of technology today you can find a flashlight battery LED, which has many significant differences from traditional models.

Main characteristics

Any flashlight is estimated for two main parameters: the range of luminescence and brightness. Often, these characteristics are interrelated and flow from each other, but there are also special versions in which this relationship does not work. As for the first parameter, powerful LED flashlights with a lens can provide a range of about 150-200 m. But even the lens does not always help maintain the width of the light coverage. To ensure a long range, it is necessary to focus the beam as it narrows. Accordingly, the beam will be "long-range", but modest in diameter. The most often used models with a range of 50-120 m. In this case, even modest in power lanterns without a lens can provide a significant diameter in the light spot.

The situation with brightness, which is expressed in lumens (Lm), is also ambiguous. The initial segment represents models at 300-350 lm. Such devices rarely provide a range of more than 100 m, and also do not differ in large spots of light. Professional devices have LEDs of 900-1800 Lm. This allows, at least, to expand the coverage zone, but in terms of range, the number of diodes used will play a significant role. For example, a rechargeable LED flashlight with two glow elements is quite capable of delivering light at 150 m in small dimensions, with a brightness of not more than 350 lm. Is the exchange of high brightness justified for the second LED? In cases where it is important to optimize the energy supply, such a configuration is indeed economical.

Battery characteristics

On the market there are still traditional lanterns on 2-3 batteries, but they are increasingly being replaced by battery models. Actually, there are two versions of batteries of this type - modern Li-Ion and aging Ni-Cd. The average voltage in both cases is 4-6 V. The volume, on which the duration of the device depends, is in the range of 1-4 A * h. Depending on the performance, the same brightness and the number of LEDs, the battery can maintain a capacity from several hours to 24 hours in continuous glow mode. And here the important thing is the battery itself, which is equipped with a flashlight rechargeable LED in a specific performance.

Nickel-cadmium blocks are characterized by resistance to temperature fluctuations, high charge velocity, but at the same time, and a short service life. More demanded lithium-ion cells, which for compact dimensions can have a large volume. But they are more expensive. By the way, you should not completely abandon the battery models, if on the other characteristics they are suitable. They can be improved by replacing the power supply system - such an operation is often subject to professional headlamp LED battery lights. Modernization at home will be reduced to the removal of the battery compartment and the installation of the battery holder. The latter can be taken from the line of conventional mobile devices.

Protective qualities of LED flashlights

Even if we are not talking about specialized applications, lanterns can be exposed to various factors of external influence - from high humidity to unforeseen mechanical impacts. And yet the most advanced in this regard are flashlights LED headlamp batteries, designed for work in mines. They are characterized by a level of protection class IP68, which means high resistance to physical damage. There are also special versions for tourists. In this case, the emphasis can be placed on the properties of water resistance. Modifications of this type, for example, can be immersed in water to a depth of about 1-2 m.

Manufacturers

In the budget variant, you can find interesting proposals from domestic manufacturers of lighting equipment. Under the brands "Bright Beam" and "Svetozar" are low-cost, but high-quality models for home use. As for special versions, modifications for construction and industry are to be found in the Camelion, Dewalt and Bosch families. Noteworthy are the hybrid LED flashlights from Hangliang. In particular, the modification of the HL-W110 is not only a flashlight, but a baton. This model is characterized by a high-strength body and a powerful stream of light. Devices with combined functionality are also offered by JTC, Enkor and others.

How much is a rechargeable LED flashlight?

The most affordable flashlights on LEDs are up to 500 rubles. This is the simplest version of a home device without special operational advantages. The market of goods also offers medium-sized models, available for 1-1,5 thousand. At the same time, much depends on the manufacturer that produces LED flashlights. China in this respect is the most democratic - for example, multifunctional versions from TrustFire cost up to 1000 rubles, but at the same time show the same power as some modifications from Bosch worth 2 thousand.

How to choose the right flashlight?

In addition to the characteristics described above, you should not forget about the functionality, adjusting capabilities and additional equipment. For household needs, there will be enough models with minimal settings. But the professional sphere may require the device to have several modes of operation, high energy-saving and auxiliary means of attachment.

Thus, LED flashlights with a lens for a powerful flow in a mine or under water are usually supplemented with special locks - wrist or the same headlamps. Regarding the adjustment possibilities, depending on the application conditions, the user will be able to optimally adjust the distance of the beam and the diameter of the spot.

Conclusion

The modern market of LED devices is steadily developing both in terms of optical filling and ergonomic properties. A successful combination of several technical and operational parameters is different even for budget LED flashlights. China also contributes to the popularization of such products attractive and because of low prices. Another thing is that quality in this case is inferior to European, and often domestic products. At the forefront of the external appeal and functionality, but the durability of battery cells and LEDs still leaves much to be desired.
