On this moment Flashlights with incandescent lamps should not be seriously considered: one of the main characteristics of any flashlight is efficiency, and in this regard LEDs there are no equals. However, LEDs are different from LEDs, especially when it comes to powerful models. The fact is that powerful LEDs They heat up quite noticeably, and overheating is literally like death for them: the rate of crystal degradation increases significantly. For cheap LEDs of unknown origin, the parameters even in the same series are seriously different, and in two externally identical flashlights, one will heat up, while the other will work without problems - and you are unlikely to like playing the lottery. Serious manufacturers (the undisputed authority here is Cree) provide much more accurate control of product parameters, and their crystals themselves have a considerable resource.
Best power supply, if you do not plan to use the flashlight for a long time in the cold, these are lithium-ion and lithium-polymer batteries, which have the best capacity-to-weight ratio at the moment. Although they are more expensive than conventional batteries, the possibility fast charging very quickly compensates for the difference in prices. If the flashlight will be used frequently, it is better to choose a model with quick-change 18650 batteries and an external charger; for occasional use, models with built-in USB charging are more convenient.
With the need for hull strength and especially protective glass, it’s hard to argue. It’s no wonder that American Maglite flashlights have earned popularity, as they can really work like a baton without the risk of damaging the flashlight itself. But, naturally, a flashlight with such dimensions is not always convenient, but modern tactical flashlights can be considered real all-rounders: they are compact (here the combination of LEDs with a lithium battery again demonstrates all its best sides), durable, and their dust and moisture protection is not an option, but norm. Therefore, they can be used even on a hike, even in the garage, or just carried “just in case” in your pocket. The main thing is to take into account the diameter of the flashlight body, since most barrel mounts are designed for diameters of 22 mm (7/8 inch) and 25 mm (1 inch).
Additional options will also not be superfluous: for example, why separately carry an external battery for gadgets on a hike, if you can buy a flashlight with a recharging function external devices? Well, a flashlight with an adjustable focus and a removable diffuser will serve both as a search spotlight and as a source of diffused light in the camp, if you turn down the brightness to minimum.
For comparison brightness a visual indicator is the maximum luminous flux, which is usually measured in lumens. Visual references are car headlights, which are also focused light sources: a regular halogen will produce about 1200 lumens, while xenon can provide 4000 lumens.
A flashlight is useful in a variety of situations: for illumination during a power outage, for searching for something that has fallen under the bed, for studying small parts or inspecting plumbing. Without this device it is difficult to imagine many types of outdoor activities, for example, it is indispensable for night fishing or cycling in the dark. Professional flashlight or simple model for household needs you can buy on AliExpress. To choose the ideal option, you need to consider the following: specifications:
- light source (incandescent lamp, LED);
- number of diodes (for LED flashlights);
- power and brightness;
- lighting range;
- presence of ultraviolet (UV) mode;
- maximum operating time;
- power supply (rechargeable or battery operated);
- protection from moisture and dust;
- additional functions;
- equipment.
Of course, you need to pay attention to user reviews. Ordinary people will talk about the advantages and disadvantages of the model in simple words, their opinion is worth listening to. The selection includes the best flashlights from AliExpress, which were appreciated by both experts and average buyers.
Best Handheld Compact Flashlights
Flashlights from this category are the most common type on AliExpress. They represent the perfect balance between functionality and size. Most often, hand-held models are purchased for daily household needs, but due to their small size and light weight, they are also suitable for forays into nature.
5 POCKETMAN 9LED
Best UV Flashlight
Price on AliExpress: from 126 rubles.
Rating (2019): 4.6
The miniature (8.8*2.5*2.5 cm) model from POCKETMAN will easily fit into your pocket and is convenient to carry. The body is impact-resistant, it is made of aluminum, the lens is plastic. Inside the device there are 9 LEDs that provide bright ultraviolet light. It is quite sufficient to work with small details, manifestations of invisible inscriptions and drawings. The illumination range here is quite modest - no more than 50 m, the beam of light is diffuse. No more is needed, given the specific nature of UV rays and the lack of standard white backlight.
The device requires 3 AAA batteries to operate; they are not included. If the batteries are replaced promptly, the service life reaches 10,000 hours, according to manufacturers. Speaking of disadvantages, some users complained about the sticky button. Reviews also note that the flashlight does not illuminate amber; it is more suitable for paper.
4 YAGE YG-337C
The most convenient battery charging system
Price on AliExpress: from 678 rub.
Rating (2019): 4.7
Unlike most flashlights from AliExpress, YAGE does not run on batteries, but on lithium ion battery. Moreover, the charging system is implemented very conveniently: the kit includes a USB cable, thanks to which the flashlight can be powered even from a laptop or power bank. A fully charged battery lasts for almost an hour continuous operation, there is an indicator showing the charge level. The remaining characteristics can hardly be called outstanding, although they are quite sufficient for everyday use: q5 LED, 5 lighting modes, beam range reaches 500 meters, brightness - 1000 lumens.
Unfortunately, the manufacturer decided to save on materials: the lens of the flashlight is plastic, the body itself is made of aluminum alloy. Among the shortcomings, reviews note the lack of elastic under the lens and the unusual connector for the charger, which makes it impossible to use cables not included in the kit.
3 Convoy S2+
High build quality
Price on AliExpress: from 1021 rub.
Rating (2019): 4.8
Convoy fully justifies the amount spent: high-quality materials were used for its production, the soldering is neat, and nothing is loose anywhere. When assembled, everything looks as if the head of the flashlight is inseparable from its main part, although in fact the device can be easily disassembled. The diode is located in the center - this is very rare for flashlights from AliExpress, where it often “moves out”. The lens has an interesting coating with a tint that changes depending on the lighting. The flashlight is powered by a lithium-ion battery.
The Convoy's low-profile hot spot makes it great for hiking and cycling in the dark. An additional advantage is the memory function: the device remembers what mode it was in before turning off, and next time it turns on with exactly the same settings. The model has one drawback: when operating at maximum power, the rechargeable flashlight heats up and quickly drains its charge.
2 Enjoydeal SGAA145A-d
The most compact. Beam width can be adjusted
Price on AliExpress: from 132 rubles.
Rating (2019): 4.9
Enjoydeal received a place in the rating for its compactness: the dimensions of the flashlight are only 9.3 * 2.5 * 2 cm. Its maximum brightness is only 2000 lumens, and the range does not exceed 200 meters, but this is quite enough for everyday use. There is only one mode, but the beam of light can be adjusted: the beam can be narrow or diffuse. The body of the flashlight is of high quality, it is made of metal. The surface is waterproof and will withstand raindrops or showers, but it is best not to place the entire device in water. The clip is rigid and holds tightly, the button is rubber and soft.
The device runs on one AA battery, it is not included. The only negative of Enjoydeal is that the compartment is too wide, the battery simply dangles in it. It’s difficult to call this a serious drawback, since it does not affect the operation of the SGAA145A-d in any way. Some users complain about the build quality, but for this price it's hard to find a better option.
1 Alonefire G700
Best brightness among hand-held flashlights
Price on AliExpress: from 372 rub.
Rating (2019): 4.9
The hand-held flashlight from Alonefire is loved by customers because of its brightness: 3800 lumens allow you to create almost daylight lighting in the room. The beam range, reaching up to 500 meters, also distinguishes the G700 from similar products from AliExpress. The flashlight body is made of high-quality aluminum alloy, so it is quite weighty, despite small sizes(13.8 cm when folded). The device runs on three AAA batteries; you can replace them with an accumulator, but it is not included in the kit.
The flashlight has five operating modes: strong, medium, weak, flashing and SOS. Reviews on the G700 are mostly positive, only occasionally there are complaints about a small defect in the form of play in the light beam adjustment unit or a biased diode. Those with large hands note that the cord here is quite narrow, making it difficult to carry the flashlight on your wrist.
The best headlamps
Flashlights from this category are placed on the head using special straps or elastic bands. The capabilities of head-mounted models are almost the same as those of hand-held models, with one exception: the mounting method allows you to free your hands and keep the light beam directed towards the person’s gaze. Thanks to this, you will be able to organize lighting exactly where it is needed, without having to constantly hold the flashlight in your hand.
5 Eshoo 3LED Headlamp
The most budget option. Attaches to headdress
Price on AliExpress: from 73 rub.
Rating (2019): 4.6
Eshoo's flashlight is not a headlamp in the traditional sense of the word. But thanks to the clip, the device can easily be attached to any headgear so that it illuminates the path. Your hands remain free, and you do not need to adjust the bandage for a long time or experience discomfort due to the heaviness of the device. The lamp rotates 90°, the clamp – 360°. The seller's assortment on AliExpress includes products in black, white and yellow.
The flashlight operates continuously for up to 5 hours; it is powered by two batteries included in the kit. The dimensions of the 3LED Headlamp are simply ridiculous - 4*2.9*2.5 mm, there are 3 LEDs inside the light bulb. Their brightness is low, only 45 lm, but this is quite enough for a late bike ride or night fishing. Some users have complained in reviews that the batteries do not work. This is due to the fact that the seller puts a protective film between them. It will need to be removed before using the flashlight.
4 BORUiT RJ-3000
There is an ultraviolet mode
Price on AliExpress: from 1017 rub.
Rating (2019): 4.7
The main feature of BORUiT RJ-3000 is the presence of UV illumination (wavelength - 395 nm). It has three lighting modes: high White light, low white and ultraviolet. The model's body is waterproof, some parts are made of aluminum alloy. The headband is elastic and easy to adjust different sizes. The light bulbs rotate 90°, this allows you to direct the beam in the desired direction.
The flashlight is powered by two batteries (1200 and 2200 mAh); a full charge will take about 7–8 hours. Manufacturers promise a service life of up to 100,000 hours. There are different configuration options: with a charger for home and car, with and without batteries. The reviews note good quality assembly and complete set. The only negative is that you cannot use white and ultraviolet illumination at the same time. In most cases this is not required, so the disadvantage can be considered insignificant.

For the convenience of users, the seller offers sets with different configurations: with and without zoom, in gift wrapping, and with a car charger. The only drawback of TRLIFE BL254 is that the same button is used to turn on, select a mode and turn off the device. Because of this, you have to manually go through all the options each time.
2 Tooniu T001
The best lens. RoHS, FCC and CE quality certifications
Price on AliExpress: from 396 rub.
Rating (2019): 4.8
Reliable and convenient, Tooniu has several advantages over its competitors. Firstly, instead of ordinary glass, a real lens is installed here. Secondly, the device has a special mechanism for focusing the light flux. And the last argument in favor of the model is that thanks to good heat dissipation, the likelihood of overheating is minimized. The Tooniu T001 has an impressive list of supporting documents: in addition to the standard PRC quality certificate, it has RoHS, FCC and CE (European Certificate of Conformity).
The power of the head-mounted device is 10 W, the brightness is adjustable in the range of 3500–5000 lm. The average illumination range is 350 m, the maximum is up to 0.5 km.

The modern lighting market offers a huge selection of lighting devices with narrow scattering angles and a long range. These are spotlights general purpose, spotlights for transport, theater stages, studios, construction sites, airfields and many others. Such lighting devices also include powerful battery-powered flashlights.
When choosing the most suitable, modern and effective flashlight, you may immediately become confused, since with all the variety of their designs, types of light sources used, range and beam scattering angle and other parameters, it is difficult to immediately settle on a specific model.
In this article we will try to understand the most important technical features of flashlights that influence the correctness of their choice.
The purpose of powerful flashlights
Powerful flashlights designed for use in difficult conditions, where a stable, bright luminous flux is required, the maintenance of which is ensured over a long period of time. Most often they are used in their work by rescue services, employees of the Ministry of Internal Affairs, speleologists and tourists. Typical representatives of this class of lighting devices are search or tactical flashlights. Also powerful are under-barrel flashlights, which are attached under the barrel of a weapon using special fasteners, camping or tourist flashlights that have a long operating time, headlamps or headlamps, the fastening of which allows them to be mounted on the head. Therefore, when choosing a powerful flashlight, you should always pay attention to what purpose it is intended for.
Special conditions, which usually use powerful flashlights, dictate special requirements for their design and light characteristics. Namely:
- shock resistance and moisture resistance of the case;
- the presence in lanterns of materials with high thermal conductivity, ensuring effective heat removal from the light source;
- battery capacity, the value of which directly affects the duration of the flashlight and the stability of its luminous flux;
- universal design of the container for installing batteries;
- possibility of adjusting the angle of dispersion of the light flux;
- the reliability of special fastenings, the effectiveness of anti-slip inserts or notches on the handle of the flashlight, the presence of a strap for carrying the flashlight on the shoulder and other nuances.
Body material and handle design
Since it so happens that search lights are the most popular on the market, we will take a look at them as an example.
For the manufacture of the body of modern powerful search lamps, anodized duralumin is often used, lightweight, durable and corrosion-resistant, on the outer surface of which either anti-slip polyurethane coating is applied, resistant to scratches and impacts, or longitudinal, transverse and diagonal notches. The body of such flashlights is mostly made in the form of a tube that simultaneously performs two functions - a handle and a container for batteries. But there are flashlights with a remote handle. Examples of cases and handles can be seen in the images below.
The images also clearly show the radiator fins, which increase the efficiency of heat removal from the light source. The ribs are made by turning the body metal mass closer to the optical part of the flashlight.
Waterproof
Flashlights have different degrees of protection against foreign objects and moisture getting inside their housing. Since all flashlights have minimal protection capable of trapping dust particles, but are not able to work when they are exposed to drops and splashes of water for a long time, they can be divided into two groups: non-moisture-resistant and moisture-resistant flashlights. According to the classification system for degrees of protection (IP - Ingress Protection Rating), non-moisture resistant ones can be assigned the value IP50, that is, dust-proof and moisture-permeable. Housings for moisture-resistant flashlights are usually produced with the ability to immerse all flashlights under water. Therefore, their degree of protection starts from IP67 and ends with IP69. Sometimes the number indicating the penetration of foreign objects is omitted and the letter “X” is placed instead of the first number (IPХ7 - IPХ9).
Let's decipher the meaning of numbers 7 - 9. Number 7 indicates the possibility of briefly immersing the flashlight to a depth of up to 1 meter. The number 8 indicates the possibility of long-term immersion of the flashlight to a depth of more than 1 meter. The number 9 indicates the possibility of long-term immersion of the flashlight to a very great depth, where there is high fluid pressure.
Sources of light
The light source is perhaps the most important element that characterizes the consumer and operational parameters of flashlights. Conventional incandescent lamps are becoming a thing of the past and are no longer used in modern powerful flashlights. Modern high-power flashlights use halogen incandescent lamps, xenon discharge lamps (HID) and light-emitting diodes (LED) as light sources.
Halogen lamps
This is an improved type of incandescent lamps and we can only talk about their advantages in comparison with traditional options. Filling the bulb of an incandescent lamp with halogen additives made it possible to increase its luminous efficiency at the same power and extend its service life by half (up to 2000 hours) by reducing tungsten burnout.
The lamps have an average light output of 22 Lm/W. This is almost twice as high as a conventional incandescent lamp, but it is still very low considering that the lamp must be operated in a portable flashlight and the energy source has a limited resource. Lamps are very sensitive to frequent switching on, during which they mostly burn out.
Like conventional incandescent lamps, halogen lamps are becoming a thing of the past as they find it difficult to compete with the long-lasting and energy-efficient LED and xenon light sources.
Xenon lamps
A characteristic feature of xenon lamps is that the electrical discharge of the lamp occurs in the inert gas xenon, at high pressure and high current densities. For this reason, the lamps have very high brightness and a visible emission spectrum close to sunlight with a color temperature of 6100 - 6300 K.
Xenon lamps have a high ignition voltage and therefore require the use of special ignition devices. After ignition, the lamps light up within approximately 15 seconds.
Xenon lamps are very sensitive to changes in supply voltage. When the supply voltage changes by ±5%, the lamp power changes by ±20%. For this reason, when using lamps of this type, it is necessary to use stabilizing devices that maintain the voltage at the same level as the battery discharges.
The light output of a xenon lamp ranges from 80 to 100 Lm/W. Xenon discharge has the highest brightness. According to theoretical estimates, its maximum brightness can reach 2000 MKd/m².
The bright, powerful luminous flux of the daytime spectrum allows you to evenly illuminate a large area, which makes such lanterns an indispensable tool for search work in accident sites, in conditions of heavy dust and gas contamination in mines, deep wells and caves. The light of the xenon flashlight is noticeable even during the day long distance, which is very important during rescue operations in the mountains and taiga.
This type of light source confidently replaces incandescent lamps and gas-discharge lamps from modern flashlight models. This fact is easily explained by the following advantages of LEDs:
- the LED, unlike a xenon lamp, is inertia-free and when a supply voltage is applied to it, it instantly reaches the nominal glow mode, just like a halogen lamp;
- the heating temperature of the LED is much lower than the heating temperature of halogen and xenon lamps;
- Since when the LED lights up, less energy is spent on heating, LEDs today have the highest efficiency - up to 45%. By comparison, a halogen lamp has an efficiency of about 5%, a xenon lamp - up to 30%;
- The maximum luminous efficiency of LEDs used in industrial production is 120 Lm/W. The average luminous efficiency of LEDs used in battery-powered flashlights is 80 - 95 Lm/W, that is, comparable to the luminous efficiency of xenon lamps.
Light distribution
Powerful flashlights can be classified both by the type of light source and by the direction of the light flux. Speaking about the direction of the light flux, we can distinguish two types of powerful flashlights:
- spotlights. The beam of light from such lanterns has a wide front and is capable of illuminating objects located at a fairly large distance, more than five hundred meters;
- long-range flashlights. The beam of light from such lanterns has a very narrow focus so that one bright spot is projected on the illuminated object, but the range of such a beam reaches one and a half kilometers. For information: the range of the flashlight is determined by the distance at which the illumination level is equivalent to the light intensity of the full moon, which is taken equal to 0.25 lux and is optimal for safe movement.
Spotlights are most effective at short and medium distances up to five hundred meters. Their most important characteristic is not the range, but the brightness of the light flux over a maximum area without deep shadow. This is ensured thanks to the special design of the reflectors. Spotlights are an ideal option for outdoor activities, hunting and fishing.
Long-range flashlights have a completely different purpose. Long-range flashlights are used by speleologists, searchers, and miners.
Long-range flashlights usually include flashlights with a lighting range of 500 meters or more. This is also ensured by the design of reflectors and optics, which allow the light beam to be focused. What is important here is not the scattering of light, but its concentration at one point, the formation of a bright light spot.
Very often, the functions of spotlights and long-range flashlights are combined in one flashlight. Structurally, such lanterns have a movable (in the axial direction) diffuser and a lens installed at the outlet. By adjusting them, they achieve the creation of a light spot of the required diameter. When adjusted, the angle of light redistribution and the focal distance between the lamp (LED) and the illuminated object change.
Rechargeable batteries
Powerful search LED flashlights mainly use two types of replaceable batteries for power supply, these are 26650 and 18650, with an output voltage of 3.7 V. Such rechargeable batteries are produced by many companies, have different prices, declared capacity values, discharge and charge times. Batteries of these types are widely used not only for powering flashlights, but also, for example, for making laptop batteries. Therefore, there should not be any difficulties in purchasing such batteries.
Different flashlight models have different numbers of batteries installed. Basically these are 2, 3 elements. There are a large number of flashlight models with a universal container designed to install 1, 2 or 3 elements by adding it to the handle special insert supplied with the flashlight.
Since 18650 and 26650 batteries have the same length, 65 mm, some flashlight models can use batteries of both types. To prevent the 18650 elements from “dangling” inside the container, a plastic adapter sleeve is included with the flashlight.
In small lanterns it is possible to install 1 element. It happens that instead of 1 18650 element, 2 CR123A elements are used.
More powerful battery-powered LED flashlights can be equipped with D-type cells with a capacity of 10,000 mAh and a voltage of 1.2 V.
In general, when choosing a flashlight, you should definitely be interested in what batteries are used in them, and what they can be replaced with. To assess the possibility of such a replacement, see the tables of standard sizes of galvanic cells.
If you decide on a search light model, remember that for it to be successful, reliable and long work Need quality batteries. I think that if you are going to spend a significant amount of money on a flashlight, you should not skimp on its most important element.
In the case of flashlights that work with a xenon lamp, from the point of view of choosing a power element, everything is much simpler. All flashlights have their own batteries, which are supplied with the flashlight. Therefore, when choosing a flashlight, you don’t need to think about anything. However, if you look at this from an operational point of view, then over time there may be problems with replacing them.
Although there are exceptions. For example, the flashlight shown in the photo below is powered by four 18650 batteries.
Operating modes
The operating modes of flashlights with a xenon lamp, due to the inertia of turning on the lamp and the limited number of its on-off cycles, as a rule, have three operating modes, namely these are the modes in which the lamp operates at different powers. Each lantern has an operating mode at minimum power, at which the lamp glows stably, an operating mode at rated power, and a forced mode, at which maximum brightness is created. When operating in the latter mode, the battery capacity is naturally consumed very quickly.
A powerful LED rechargeable flashlight, in addition to the listed operating modes of xenon flashlights, has two additional modes work is:
- stroboscopic mode. This mode designed for self-defense from an attacking enemy, by disorienting him in space with very bright and frequent light pulses;
- SOS mode or beacon to attract the attention of strangers to you.
To summarize, we can conclude that powerful flashlights with halogen incandescent lamps have faded into the background. The leadership is shared by flashlights with xenon lamps and flashlights with LEDs. However, LED high-power flashlights have characteristics comparable to flashlights equipped with xenon lamps, and therefore are increasingly used.
And finally, we invite you to watch a video review of two portable, powerful rechargeable LED flashlights made in China and Germany.
The most powerful flashlight is chosen by those whose profession or lifestyle involves extreme conditions. These are employees of the Ministry of Internal Affairs, volunteers in rescue teams, rescuers from the Ministry of Emergency Situations, as well as tourists and speleologists.
Such lighting devices must constantly maintain a bright and stable luminous flux for a long time. The leading positions in this niche are occupied by search or tactical flashlights. Also quite powerful are under-barrel models, which are attached under the barrel of a gun, and tourist models, which have a long operating time.
Characteristics
The special operating conditions of powerful flashlights dictate special requirements both for the design and for the light parameters:
- High brightness. Basically, the brightness of powerful flashlights starts at 1000 lumens. About this much is required to properly illuminate an open area.
- Long range. To illuminate not only the space around you, but also at long distances. Maybe from 500 meters or more.
- Nutrition. The flashlight must have several batteries and a powerful battery so that its owner does not find himself in the middle of a night forest without light.
- Several modes of use. The powerful mode is used in open areas, the weaker mode is used in confined spaces, and the minimum mode is used to preserve charge and emergency lighting.
- Shockproof and waterproof case. For use in extreme conditions, search lights are made of heavy-duty materials and are completely waterproof.
- Heatsink. Good heat dissipation is prerequisite safe use, because powerful diodes heat up the case very quickly.
- Lamps. Today, LED flashlights and models with a xenon lamp are popular. This is due to the fact that they are more durable, heat up less and have greater light output. But halogen incandescent lamps are becoming a thing of the past.
Weight, ergonomic design and dimensions also play a role when choosing a powerful flashlight, but they do not always come first, giving way to other, more important characteristics.
Spotlights
A powerful flashlight can serve as a replacement for a long-range flashlight and, in some respects, is one. His distinguishing feature is a flood light that has a large illumination radius (from 300 to 500 meters). This is why it is great for search operations.
Externally, the flashlights are a fairly large structure, including several powerful diodes and an external battery. They can be charged from a regular outlet, and most models also provide charging from the cigarette lighter in the car.
The operating time of spotlights varies within an hour, if used on full power. The brightness of this lighting device is from 5000 to 8000 lumens, depending on the model. For comparison, a 100-watt light bulb has only 1,500.
For all their advantages, such powerful portable flashlights are inconvenient because they weigh quite a lot and do not have a very ergonomic design. And this can create problems with long-term use, when you need to move on foot.
Hand flashlights
A hand-held flashlight has a familiar shape and is more convenient to use than a spotlight. Although it is unlikely that it can be carried in a pocket. High power requires appropriate batteries. The brightness of such lighting devices starts from 1000 lumens and is limited only technical capabilities.
The Torch is recognized as the most powerful hand-held flashlight in the world today. The brightness of this flashlight is 4100 lumens, and its light can illuminate a large area. But, as always, there is a fly in the ointment: such power also requires appropriate power, the batteries will be discharged in about fifteen minutes.
Headlamps
The headlamp has gained great popularity among those who need bright lighting and at the same time free hands. Of course, its brightness will be significantly inferior to long-range flashlights, but all this is relative.
The brightness of powerful headlights ranges from 600 to 1000 lumens. The strongest in this class has a brightness of 1010 lumens. It should be noted that a bright flashlight will not help so much as hinder. After all, the light source is located directly above the eyes and can simply blind, and this is already fraught with consequences.
As you can see, all flashlights are different, and each can be called powerful in its field. It all depends on the scope of application and the desired characteristics.
