LED Power Lights

Today, a lot of effective solutions are presented on the market of lighting devices. The most powerful lanterns are distinguished by narrow angles of dispersion, an impressive range of action. However, due to the variety of designs in choosing a flashlight, you can come to some confusion. So let's try to figure out which characteristics are of particular importance when selecting a good flashlight.

Appointment

Powerful lights are designed for use in the most difficult conditions. The need for their operation arises when it is necessary to create bright, stable lighting, which can be maintained for a long time period.

Headlamps powerful are often used in the course of rescue operations, hiking tours, speleological sorties. To devices of this category are, first of all, tactical and search lanterns. Sufficiently high user characteristics are characterized by underbarrel and camping lighting devices. Thus, selecting powerful lanterns, it is necessary to start from features of the future application.

Defining requirements

Proceeding from difficult conditions in which the powerful lanterns are predominantly used, the following requirements for the characteristics and design of such devices are required:

• Moisture resistance and impact resistance of the case;
• The use of materials with high heat conductivity as production bases, which facilitates the rapid removal of thermal energy from the source of illumination;
• High battery capacity;
• The possibility of adjusting the luminous flux in a wide range;
• Reliability of fasteners and additional components.

Differences of LED lighting from incandescent lamps

A flashlight with a powerful LED has obvious advantages over devices where an incandescent lamp is used as a source of illumination. First of all, they are heavier to damage, since the LED is no more than a miniature semiconductor with a light-emitting coating.

The efficiency of incandescent lamps reaches about 30 lumen / Watt. At the same time, a powerful LED flashlight is capable of displaying more than 130 lumens per watt of power consumption. As a result, LED-based devices provide a stable light flux for a longer time with a similar energy reserve.

Lantern LED powerful is able to function for 50,000 hours of continuous operation. For incandescent lamps, this indicator is not more than 5,000 hours. At the same time, the use of LED elements as an illumination source opens the possibility for brightness adjustment in the widest range.

Housing

The most high-strength today is the search model of LED lights. The anodized duraline is often used as the basis for the body. The material is durable and light, resistant to corrosion, shock, scratches.

Such bodies in the main body are made in the form of a monolithic tube, which simultaneously plays the role of a container for the batteries and the handle of the lighting fixture. However, there are duralmine shells with remote handles.

Distribution of light

Hand and headlamps powerful are most often classified according to the light source. However, the determining factor here is the direction of the light flux. Based on this indicator, the following types of lanterns are distinguished:

1. Projectors - a light beam covers a wide range. The most powerful lantern of this plan is able to illuminate objects at a distance of about 500 m.
2. Long-range models - a beam of light is distinguished by a rather narrow focus, which leads to the formation of one bright spot on the object. The range of action here can reach about 1500 m.

The projectors are effective at medium and short distances. Their defining characteristic is the formation of a bright light flux without the appearance of a deep shadow. This is due to the specific design of the reflectors. As a result - floodlights are the ideal solution for hunting, outdoor activities, fishing.

Completely different destination for long-range devices, which are widely used by speleologists, search crews, miners. The design features of optics and reflectors contribute to precise focusing of the light beam. Important here is not the scattering of rays, but the formation of a saturated light spot at one point.

The nature of the light flux

The LED flashlight can reproduce a warm or cold glow. It is determined by different color temperature. The choice of a "warm" light emitting diode, yellow, blue or any other shade depends on the individual perception of the user and the tasks assigned.

If to speak about a cold glow, here there is a worse color rendition. When the cold diode glows, the same grass may not look green, but rather gray. However, this comparative disadvantage does not matter when using a lantern in winter or using it indoors.

When using flashlights in certain fields of activity, the value of preserving the illuminated objects of natural color is of importance. Especially when it is necessary to distinguish between small shades of objects. For these purposes, "cold" LEDs may not be suitable.

Food

Supply of a lighting source with energy is possible from a battery or batteries. Lantern battery powerful is expedient to operate in conditions when there is an access to the electric network that allows to make timely recharging of storage elements. The use of battery-powered devices looks like a rational solution when organizing long trips. Naturally, the latter option is more expensive in terms of material.

Operating modes

Powerful lights usually work in three modes, each of which is characterized by a separate power consumption. In each lighting device, it is planned to operate at minimum power, when the lamp gives a moderately bright illumination, as well as in the nominal and forced mode, where the brightest light is produced.

In addition to the above modes, powerful lights are able to work in additional modes:

1. Stroboscopic - activated if self-defense is necessary by disorienting the enemy with a saturated or frequency light pulse. Is not present in all models of high-power LED lights.
2. SOS mode - used in emergency situations to attract the attention of rescuers or others.

Finally

As a result, it should be noted that choosing the most powerful flashlight, preference should be given to LED devices, since devices with incandescent lamps are obsolete by modern standards. LEDs are extremely durable and economical in terms of energy consumption. Thanks to a long service, the lighting source does not need to be replaced frequently. In general, choosing the most powerful flashlight should be based on the goals for which it will be used.
