Lamp type

The type of lamp installed in the flashlight.

Nowadays, the most widespread models on LEDs(with or without a reflector). Halogen lamps are used much less frequently (alone or in combination with LEDs), xenon lamps, krypton lamps, fluorescent lamps, and in some models you can even find classic incandescent lamps. A separate type of light source is a laser. Here is a more detailed description of the most relevant options for today:

— LEDs. They can also be referred to as LED — an abbreviation of the English name. The most advanced type of lamps today, used in the vast majority of modern flashlights. One of the key advantages of LEDs is extremely high efficiency — as a result, they provide excellent brightness with low power consumption and small size, and they practically do not heat up during operation. LEDs can be made both in the form of separate point light sources and in the form of COB panels of a fairly large area; see Diode Model for details. Also, such light sources are resistant to shock, shock and low temperatures; with all this, they are generally inexpensive and have practically no noticeable shortcomings.

— LED with reflector. In lanterns with this type of lamp, LEDs (see above about them) are installed in special-shaped recesses covered with reflective material. Thank...s to this design, the light emitted by the LED to the sides is reflected and directed forward, in the same direction as the main stream. This significantly increases the overall brightness of the flashlight, which is especially important for compact models with a single LED of relatively low brightness. Actually, most compact types (see "Type") have just such a lamp design.

— Halogen lamp. One of the most popular modifications of a classic incandescent lamp: the light source is a hot metal spiral in a sealed glass flask filled with gas with the addition of bromine or iodine vapor (these substances are so-called halogens — hence the name of the lamps themselves). This has a positive effect on efficiency and allows you to achieve a fairly high brightness; so that modern lanterns with such lamps are usually referred to as hand-held lamps. At the same time, even in such devices, such lamps are becoming less and less common, being replaced by the LEDs described above.

— LEDs / halogen lamp. The combination in the design of the two light sources described above at once; usually the "halogen" is installed in the centre, and the LEDs are around it. At one time, this combination appeared as an attempt to create sufficiently powerful lighting devices that would consume less energy than analogues with halogen lamps, while costing less than pure LED ones. In addition, such a design provided additional features for adjusting the operating mode: it could be changed simply by turning on the existing light sources together or separately. However, with the development and cheapening of LED technologies, this option has practically lost its relevance; today it is extremely rare.

— Xenon lamp. This term can mean two types of light sources: one of the modifications of an incandescent lamp, where the bulb with a spiral is filled with an inert xenon gas, or a gas discharge lamp, in which the light source is an electric arc in the same xenon medium. The first variety was used mainly in small pocket flashlights, the second — in hand lamps. At one time, xenon lamps (both varieties) had very decent indicators of efficiency and brightness, although they were not cheap. However, again, the development of LEDs made the production of flashlights with such lamps impractical.

— Incandescent lamp. In this case, we mean classic incandescent lamps that do not belong to more advanced varieties — halogen, xenon, krypton, etc. Recall that the light source in such a lamp is a hot metal spiral in a glass bulb, which is filled either with vacuum (in miniature light bulbs), or a mixture of argon and nitrogen (in larger ones). Anyway, such lamps nowadays are considered completely obsolete — primarily due to low efficiency, which results in low brightness with significant power consumption, as well as strong heating during operation. However, nowadays this option can still be found in individual lamps — mainly hand-held lamps for the construction industry, powered by standard replaceable batteries for power tools. "Gluttony" in terms of energy consumption for such lamps is not critical, and the bulbs themselves are extremely cheap.

— Laser. The laser beam itself has a high effective range, but a small thickness. Therefore, flashlights with such light sources are usually equipped with adjustable optics, with which you can scatter the beam and turn its “imprint” from a point into a fairly large spot. Typically, laser flashlights have a specific purpose: illumination and target designation when hunting at night (for this, a mount on an optical sight is often provided), giving light signals, etc. Note that when using such devices, care must be taken: if it gets into the eyes, the laser beam can not only blind, but also cause irreversible damage, even at a fairly large distance.

The remaining types of lamps nowadays are practically ousted from the market by LEDs and are found mainly in frankly outdated models. It makes no sense to describe them in detail, we note only the key features:
  • Fluorescent lamp. One of the names for fluorescent lamps, known colloquially as "fluorescent lamps". The luminous flux itself turns out to be scattered, so such light sources were used mainly in tourist lanterns and individual models of hand-held lamps.
  • krypton lamp. An incandescent lamp with a bulb filled with krypton to increase brightness and reduce heat. Due to the high cost of the filler, such lamps were mostly made miniature and used in lanterns of the appropriate size.

Number of diodes

The number of LEDs (see "Lamp type") provided in the design of the lantern.

At first glance, the more LEDs, the more powerful this model. However, in fact, things are not so clear cut. Firstly, one high-end LED may well provide more light output than several inexpensive diodes. Secondly, modern luminaires can use both traditional LEDs and arrays of numerous miniature diodes on a common basis. Such arrays can be implemented using SMD technology or more advanced COB; the differences between these options are described in more detail in the Diode Model section, here we note that a solid SMD or COB plate is also considered to be 1 LED — despite the fact that in terms of luminosity it can exceed conventional LEDs by several times, or even orders of magnitude.

Thus, it is hardly worth directly evaluating the brightness and efficiency of the flashlight by this parameter. But what the number of diodes often directly affects is reliability: most “repeatedly charged” lamps are able to continue working even if some of the diodes fail. In addition, in some types of flashlights — in particular, tourist models and hand-held diffused lamps (see "Type") — each LED illuminates a separate sector, and together they cover a full 360 ° horizontally.

Max. luminous flux

The maximum luminous flux provided by the lantern.

Luminous flux (denoted in lumens) can be described as the total amount of light produced by an LED or other light source and distributed in all directions where this source shines by itself (without lenses, reflectors, etc.). In fact, this means that the capabilities of the flashlight depend not only on the luminous flux, but also on the angle of illumination (see "Angle of illumination (light)"). For example, a relatively weak stream can be concentrated into a narrow beam, providing good range; and a large number of lumens will inevitably be needed to effectively cover a wide area.

Note that the coverage angle is not always specified in the characteristics, and even with such data it is difficult to immediately assess the real capabilities of the flashlight. Therefore, for such an assessment, it is best to use information about the actual illumination range (see below), and also take into account the general type of device (see above). For example, for the same number of lumens, a handheld flashlight with a reflector to form a directional beam will give a noticeably greater range than a tourist lamp with 360 ° coverage.

It should also be borne in mind that the high brightness of the flashlight is far from always justified, and it is worth choosing according to this parameter, taking into account the actual conditions of use. S...o, when working at short ranges, bright light can become a hindrance: it tyres the eyes and can blind others. In addition, an increase in brightness usually requires more powerful sources of both light and power, and the weight and dimensions of the lantern increase accordingly.

Lighting range

The maximum range at which the flashlight provides any effective illumination of objects. Different manufacturers have different criteria for this efficiency when measuring ranges, and therefore it is only possible to unequivocally compare among themselves in range only models of one manufacturer. At the same time, this parameter allows us to compare models from different manufacturers with some certainty: for example, flashlights with a lighting range of 15 m and 100 m will clearly belong to different range classes, regardless of manufacturers.

Note that the range of illumination depends not only on the maximum luminous flux provided by the lantern (see above), but also on the features of its design: the narrower the beam is provided by the reflector of the lantern, the greater the range will be, and vice versa — scattered light does not spread far. Some models allow you to adjust the beam width depending on the requirements of the situation (for more details, see "Adjusting the focus").

It is also worth bearing in mind that models with the same claimed lighting range can cover different spaces. For example, a hand lamp (see Type) with a reflector diameter of 20 cm will be able to provide a wider beam than a conventional hand lamp with a 5 cm reflector. And although in both cases the objects that fall into the light spot will be illuminated in the same way, however, in the first case, the size of the spot itself will be larger, and the actual efficien...cy of the flashlight will be correspondingly higher (in light of the fact that it is easier to "feel" individual objects with a wide beam, especially at a considerable distance).

Max. operating time

Maximum runtime of the flashlight without changing batteries or recharging the battery.

Note that in models with brightness control, this time is indicated for the most modest and, accordingly, economical mode. For example, in a flashlight with a maximum luminous flux of 1000 lm, the claimed operating time of 20 hours can be achieved at a brightness of only 30 lm, and at maximum battery life may not exceed half an hour. These nuances should be clarified according to the detailed characteristics. However, also note that additional modes of operation (see below) are not taken into account in this case: for example, if the flashlight from our example in SOS mode can operate for 30 hours, the characteristics will still state 20 hours.

It is also worth bearing in mind that for models with replaceable batteries, the actual operating time will also depend on the quality of such batteries. For example, for flashlights for AA and AAA elements, battery life is most often given when using high-quality alkaline batteries; if instead of them inexpensive saline ones are used, the operating time may be several times shorter.

In general, when choosing a flashlight according to the maximum operating time, it does not always make sense to focus on “long-playing” models: they often have either low power or impressive weight / dimensions, and the price can significantly “bite”. Flashlights with a long battery life will be useful first of all to those who have to s...tay “away from civilization” for a long time: extreme tourists, rescuers, military, etc. And for most everyday tasks in a modern city, and even for trips to nature for several days, up to 10 hours is enough.

Brightness levels

The number of brightness levels provided in the flashlight design. Most modern models have one level of brightness, but there are models with the ability to adjust. Several levels of brightness allow you to choose the best option for a particular case: for example, to view a small room, you can reduce the brightness and save battery power, while in a large warehouse you may need full power of the flashlight. Accordingly, the more brightness levels are provided in the design of the flashlight, the wider your options for choosing the best option will be.

Also note that in addition to step-by-step brightness adjustment, with fixed levels, modern flashlights can also be used with smooth adjustment. It is detailed below; here we note that the stepped format is technically simpler, cheaper, and therefore is used much more often. And in individual lamps, these options are combined — for them, the characteristics indicate both the number of individual brightness levels and the presence of smooth adjustment. The specific way to implement such a combination may be different. For example, a brightness control ring can have several fixed levels with clear values, and the ability to set any intermediate position between these values; the main mode of operation with smooth adjustment can be supplemented with a fixed level of reduced or increased brightness; etc.

Shockproof

Additional resistance of the flashlight to various kinds of shocks and shocks. The specific degree of shock protection for different models varies, sometimes quite noticeably; This point should be clarified according to the official documentation. At the same time, the vast majority of shock-resistant models are able to transfer at least a fall from their hands onto a hard surface without consequences, and anyway they are more durable than unprotected flashlights.

It is recommended to specially select a shock-resistant model, first of all, if your activity involves a corresponding risk — for example, extreme tourism, speleology, military affairs, security activities.
