LED lighting is harmful to health. Is there any harm to human health from LED lamps?

LED lamps have recently become a popular topic for discussing the benefits of new energy-saving technologies in lighting. As for saving energy, everyone is already well aware of the advantages that LED lamps have.
But, …

But it turns out that LED lamps can bring certain benefits to human health.
Fluorescent, metal halide lamps and other gas-discharge lamps, as well as incandescent lamps, create fluctuations in light output that are invisible to the human eye. Sometimes, as in the case of fluorescent lamps, where the oscillation frequency is not too high, flickering of the lamps can be noticed. It is clear that the human eye will get tired faster under the influence of such lighting. The consequence of such daily fatigue can be deterioration of vision.
Of the above types of lamps, the most harmless to human eyes are halogen lamps. The flickering frequency of such lamps is the highest. The most harmful are fluorescent lamps. These lamps have the lowest oscillation frequency.
Concerning LED lamps, then LEDs, as a light source, do not create vibrations harmful to the eye.
The light from LED lamps is clean and does not contain harmful UV radiation. Of course, modern halogen and metal halide lamps, as sources of increased UV radiation, have UV filters in their glass. But even these safety measures can only minimize harmful radiation.
Let me remind you that ultraviolet radiation can cause cancer. Therefore, well-known manufacturers, such as BLV, PHILIPS, OSRAM, GE, are required to use filters for their lamps. LED lamps, as you understand, do not need filters.
Fluorescent lamps, including CFLs (compact fluorescent lamps), are recognized as a source of increased danger to human health in the United States. The fact is that mercury vapor contained in fluorescent lamps can, if the lamp breaks, cause serious illness or even death. This is not a joke! Several lawsuits have already been filed in America against fluorescent lamp manufacturers!
LED lamps will not cause any harm to the human body, even if they break. LEDs are non-toxic and do not emit any harmful substances into the atmosphere.
LED lamps consist of more than just LEDs. The components of LED lamps are aluminum reflectors, metal bases, parts of microcircuits for LED power devices, and glass.
Aluminum products, when it comes to dishes or cutlery, can be harmful to health over many years of use. Aluminum accumulates in the body over time and can cause serious metabolic disorders. However, we are not going to eat with LED lamps!
As for other potentially hazardous parts of LED lamps, the glass used in LED ball, candle or T8 LED lamps is not glass at all. This is a thin translucent plastic that, even if it breaks, will not cut anyone!
The chip parts used in LED lamps, of course, may contain heavy metals or other harmful compounds. But serious poisoning with these quantities of harmful substances can only occur through prolonged direct contact or consumption.
LED lamps do not emit infrared radiation. Infrared radiation itself, as scientists say, is harmless to humans. But, in my opinion, the less radiation of any kind, the better. The absence of the infrared spectrum in the light of LED lamps turns out to be very useful from another point of view. When illuminating various objects with LED lamps, the light of LED lamps does not interfere with infrared sensors and video cameras. Companies offering security systems have already paid attention to this positive point.
Still, it’s worth being honest and saying that LED lamps create radio interference with FM receivers. We discovered this amazing fact recently while replacing a faulty incandescent lamp in our office with an LED lamp. Near the installation site of the LED lamp, at a distance of no more than 1 meter, there was an FM receiver. Apparently, the lamp power supply is causing this interference. In general, FM radio waves are not a source of danger to human health. However, it is still necessary to warn about this fact.
Another positive characteristic of LED lamps is the absence of thermal radiation. LEDs produce heat, but it is absorbed by the aluminum reflector of the LED lamp. The amount of heat generated is several times less than that of incandescent or halogen lamps.
Summarizing all of the above, LED lamps are practically harmless to human health. When used in indoor lighting, LED lamps can bring the greatest benefit to human vision. There is no flicker or harmful radiation. Also, LED lamps will help avoid harmful effects on the skin. And if it happens that the LED lamp breaks, then you will not be poisoned by mercury vapor, as is the case with CFLs.

LED lamps and LED lightening in general, it is used in our lives more and more often. It is used for lighting industrial and domestic premises, residential buildings, streets, and is also used in computer screens, televisions and other gadgets. And this is justified. With very little energy consumption, we can get a powerful luminous flux and a long service life. But today this is not what interests us. We are interested in the safety of LED lamps, their impact on human health and physiology, and the harm of LED lighting.

Without a doubt, incandescent lamps are the safest; they do not contain any complex components or heavy metals, do not emit ultraviolet radiation, do not flicker, and produce light most similar to natural lighting. With the advent of fluorescent lamps, people began to think about their safety. They contain mercury vapor, which will cause very negative consequences when the lamp is broken, constantly flicker and this is harmful to the eyes, and also emit electromagnetic radiation due to the use of electromagnetic coils.

When LED lamps appeared, it seemed like a panacea; they consume minimal energy, do not contain harmful substances and almost do not flicker. But is everything as good as it seems? In this article we will try to figure it out. Undoubtedly, the safety of LED lamps is higher than daylight, but they have their own dark side.

Safety of light

Scientists from Spain working at the University of Madrid have found that staring at an LED lamp for a long time can damage your eyesight. In most LED lamps to obtain white light A combination of blue and yellow LEDs is used. The yellow LED is not dangerous, but the blue one can cause problems. It emits blue and violet light at very short wavelengths with great energy and power. Looking at such a light source for a long time and continuously can damage the retina of your eye. LED lamps cause three types of damage to our eyes: photomechanical (impact energy from the light wave), photothermal (heating of tissue from radiation) and photochemical (photons of light can cause chemical changes in molecules).

But this drawback is easy to deal with. Just don't look at the bright LED lamp for too long. The same rule applies to fluorescent lamps; in this regard, they are much more harmful, since they emit direct ultraviolet light, which, in terms of harm to the eyes, is not comparable to the radiation of LED lamps. It was necessary to mention the dangers of light from LED lamps so that you do not think that they are safe in this regard.

LED lamps and physiology

Israeli scientists conducted a study of the effect of lighting on the release of the hormone melatonin. It is produced by the pineal gland and affects sleep patterns, blood pressure and brain function. But most of all, this hormone controls sleep; the more hormone in the blood, the more a person wants to sleep.

Scientists have found that white and blue colors reduce the release of melatonin. The bright blue color has the greatest effect on the release of this hormone. This happens because over the centuries our body has become accustomed to the fact that in blue light, we need to stay awake during the day, and when yellow light When the sun sets, it's time to sleep. This harm from LED lamps applies to any bright artificial light sources. For bedrooms, it is recommended to use incandescent or LED lamps with a low color temperature - 1000-1500 Kelvin. It is also recommended not to look directly at a bright light source two to three hours before going to bed.

Harm from flickering lamps

It would seem that LED lamps do not flicker, but not everything is so simple. In fact, all the lamps are flickering, we just can’t see it. Even incandescent lamps running on mains power alternating current flicker at a frequency of 100 Hz. Low-quality LED lamps may flicker at an even lower frequency. For LEDs to work you need D.C., and the network has alternating current, the easiest way to get direct current is to weed out some of the pulses, which will give an uneven flow of electricity and, as a result, flicker. Our consciousness is not able to notice the flickering of lamps due to its inertia, but the brain can detect it up to a frequency of 300 Hz. Fluctuations from low-quality LED lamps can cause some harm to the body; they change hormonal levels, reduce performance, and increase fatigue.

In high-quality LED lamps from well-known manufacturers, the flicker frequency is above 300 Hz and our brain cannot detect it, therefore it does not affect. This reduces lamp flicker to zero. You can check for yourself whether your lamp is flickering; all you have to do is look at it through your phone’s camera. If the flicker frequency is below 100Hz, you will most likely see flicker. See more details:

Electromagnetic radiation

electromagnetic radiation safety

Each LED lamp contains an electrical circuit. As I already said, to power the LEDs you need constant pressure. Therefore, to transform AC voltage a special one is used on a regular basis electrical diagram, generating high-frequency pulses (to avoid flickering). Electromagnetic interference is created around the light bulb, which can disrupt the operation of household appliances. It is not recommended to place devices such as radios, televisions or other sensitive equipment close to the lamp.

Heavy metals and hazardous substances

Unlike fluorescent lamps, LED lamps do not contain any hazardous elements. All that is there is a completely safe semiconductor from which the LED, lens and housing plastic are made. Fluorescent lamps contain mercury vapor, while the lamp is sealed, it is completely safe, but when the integrity of the housing is compromised and mercury spreads throughout the room, it can cause damage to the respiratory system. But, fortunately, this disadvantage is not inherent in LED lamps.

Fire safety

In this aspect, the safety of LED lighting is also at a high level. As you know, ordinary lamps incandescent bulbs get very hot, and if you touch a light bulb that is not working, you can get burned. But the LED lamp will be barely warm even after several hours of operation. It does not heat the air around it and will not cause a fire even if it comes into contact with flammable substances.

Danger of direct light

harm from direct light

Looking at bright light sources is not recommended. This can cause serious harm to your eyes and cause retinal burns. If you look at an incandescent bulb or most LED bulbs with a diffuser for a few seconds, you probably won't have any problems. But direct exposure to a bright, unscattered light beam can damage the retina. This does not apply to household LED lamps, but is suitable for other devices, such as flashlights.

conclusions

LED lamps are not as dangerous as fluorescent lamps. They do not contain any harmful substances that can be released into the atmosphere if you break the lamp, they do not have very harmful low-frequency flicker that affects the eyes, but they still have disadvantages that you need to learn to work around. Now you know what to consider when buying an LED lamp. The harm of LED lamps can be minimized by choosing a quality product. First of all, you need to take a quality product that will not harm your health and will last you a very long time.

LED lamps appeared on the world market relatively recently, but today they are in quite high demand. This is explained by a number of advantages of these light sources. For example, unlike conventional incandescent lamps, they do not heat up, due to which they use electrical energy economically and last much longer.

You can name a number of other advantages that LED lamps have. But thanks to marketers, almost every person who has at least once been faced with the choice of light sources for their home knows very well about them. In this article we will look at fairly common statements that these products are harmful to human health, and we will also try to find out which of them can be called truth and which is a myth.

The lamps contain substances that are harmful to health.

We'll start with the most common horror story, which claims that LED lamps contain toxic substances and are therefore harmful to human health. Is it so? To answer this question, let’s consider in detail all the design elements of the product:

• body, for the manufacture of which polymer materials are used. It is quite possible that in low-quality light sources it is this that poses a danger, since little-known Chinese manufacturers often skimp on raw materials. But if you choose branded devices, you can be sure that the plastic is safe;
• base Materials: nickel-plated steel. Exactly the same from which the base of a regular incandescent lamp is made;
• a driver responsible for the uninterrupted operation of the product during voltage surges. It is equipped with radio components that are also absolutely safe;
• radiator providing effective heat removal. Made from anodized aluminum, which today can be found in the design of a wide variety of products used in everyday life;
• printed circuit board on which the microcircuits are located;
• diffuser, which is a flask. Unlike fluorescent and halogen light sources, it is not filled with gas, which indicates a high level of safety.

So, the presence of toxic substances in the design of the product is a myth.

In fact, they are just as harmful as any modern electronic device.

Flickering lamps harm your eyesight

Like other sources, LED lamps flicker during operation. Their pulsations can negatively affect the human nervous system. And even if you don’t observe any glare. Therefore, statements about harm are true? Let's not rush to conclusions.

The thing is that high-quality LED lamps are equipped with very efficient drivers, the output voltage of which is filtered and almost completely eliminates the variable component. Thanks to this, the pulsation coefficient of such devices does not exceed 10 percent, which is the norm. Yes, LED lamps with a high-quality driver are expensive. But they also serve for a very, very long time, without causing any harm to eye health.

LED light sources inhibit melatonin production

Another popular horror story tells us that the bright light of LED sources triggers hormonal changes and prevents the production of the sleep hormone melatonin, which is why they are very harmful. This statement is partly true, since the brightness of the product is quite high. To eliminate the negative impact of lamps on the body, you should not use LED lamps in the bedroom.

In addition, we can recommend avoiding working at the computer (modern digital devices use LED backlighting), and turning off the TV at least an hour before bedtime. This will restore normal melatonin secretion, as well as normalize oxidative processes in the body, leading to early aging.

Continuing the topic, we can say that LED lamps activate the production of a hormone such as serotonin in the human body. Unlike the already mentioned melatonin, it increases performance. That is why it is best to use LED devices where you intend to work - in an office or library, in an office.

White light from LED bulbs negatively affects vision

When purchasing LED lamps, you need to pay attention not only to such an indicator as the pulsation coefficient (as we have already found out, the smaller it is, the safer the device), but also the color temperature. If it exceeds 3200 K, the intensity of radiation in the blue spectrum increases significantly, which negatively affects human vision. Its constant exposure can lead to dystrophic changes in the retina and cornea of ​​the eye, and other very unpleasant consequences.

Cold white light is dangerous for children's vision. The thing is that the child’s visual system is at a developmental stage and any negative impact on it can lead to undesirable consequences. To prevent this from happening, we recommend paying attention to the following characteristics of LED bulbs:

• pulsation coefficient – ​​no more than ten percent. As we wrote above, this result is achieved by using high-quality and very expensive drivers. But health is more valuable;
• Colorful temperature. It is best if it is in the range of 2700-3200 K;
• lamp power. You should pay attention to this parameter if you use lamps or chandeliers with two or more light sources. In this situation, it is better to use not too powerful LED lamps (maximum 40-60 watts) to minimize harm to eye health.

Harmful infrared and ultraviolet radiation

We will immediately declare this horror story a myth, and here’s why. All LED lamps produced today are manufactured in two main ways:

• the first involves producing white light by installing three crystals - red, blue and green. They are housed in one plastic case, work smoothly and do not emit in either the IR or UV ranges. Devices with a similar design are the safest, but they are quite expensive;
• The second way to produce white light is to use a substance such as a phosphor, which is applied to blue LEDs. In this case, the lamps do emit infrared radiation, but the intensity of such radiation is no more than 15 percent. This is significantly less than conventional incandescent light bulbs.

Is LED lighting harmful to human health, what effect does such light have on the retina of the eye, why is cold light dangerous for children, and which LED lamps are safe? You will find answers to all these questions in our review.

Cool or warm light?

It has long been known that LED lamps, LED panels, spotlights and other LED-based devices consume energy sparingly and have an extremely long service life. Many people also know about the advantages of new lighting devices, such as no need for maintenance and repair, operation without heating, excellent light contrast and a high color rendering index. But as for eye safety, which is claimed by manufacturers and sellers, everything is somewhat more complicated.

Over the hundred-year history of using an incandescent lamp (Il), no damaging effect on the eyes of the artificial light produced by this device has ever been detected. LN created an acceptable level of lighting in the evening and night hours, which did not cause noticeable discomfort.

But time dictated the need to find more economical light sources, since electricity tariffs always tended to increase, and saving on lighting was inconvenient and harmful to vision. Thus, fluorescent lamps appeared in commercial, industrial, and later residential premises, and in recent years, light-emitting diode lamps (LED).

At first, few people paid attention to such an indicator as color temperature. Moreover, it was believed that the so-called daylight white light was as close as possible to midday sunlight on a cloudless day, and therefore good for the eyes. As it turned out later, this is not so, or rather not entirely so. Users of fluorescent and LED “white” lamps themselves began to notice that in the evenings this lighting irritates the eyes and causes noticeable discomfort. Why?

It's all about the wavelength!

A study of lighting parameters with LED lamps showed that white LED lamps have a pronounced emission band in the blue-blue range with a wavelength of about 450nm. If a person is exposed to short-wave cold white light in the evening or early morning, the production of melatonin in his body sharply slows down. This does not have the best effect on health, since this hormone affects many functions of the body. In particular, it regulates natural biorhythms and supports the normal functioning of the immune and hormonal systems. In addition, melatonin has powerful antioxidant properties, influencing the aging process to slow it down.

Scientists have found that melatonin production is most strongly inhibited by lamps with a high color temperature, which shine in the blue-blue spectrum. Use the same LED lamps(LED) with color temperature 4000K and below is not associated with such harmful action. The lighting created by such lamps is similar to the warm yellowish light of LN.

However, all of the above applies rather to household lighting devices. In industrial and street lighting(main luminaires, lanterns, LED spotlights, etc.) it is allowed to use LEDs with higher color temperatures.

Features of using LEDs for lighting children's rooms

For children's eyes, short-wave cold light produced by light-emitting diode (LED) lamps is doubly dangerous, since it can eventually cause damage to the retina and a sharp decline in vision. Reason: the lens of a child's eye is twice as transparent as an adult's in the blue-blue spectrum.

In this regard, there is a risk of photodamage to the retina under the influence of cold white LED lamps with a large proportion of blue or violet in the spectrum. Research in this area is still underway, but from the results obtained we can already conclude: in children's rooms it is advisable to use only light-emitting diode (LED) lamps, which emit the same warm yellowish light as incandescent lamps. The color temperature of these lighting fixtures should not exceed 3000K.

For adults, cold short-wave light is dangerous only in the evening and night hours, as it interferes with the normal production of melatonin. Experts warn that LEDs with a color temperature of 6500K and above it is better not to use even by adults. In any case, until research data appears that refute the harmful effects of short-wave light on the human body. In the meantime, when purchasing household LED lamps, which undoubtedly have many advantages, you should pay attention to such an indicator as color temperature. As a rule, it is indicated on the packaging.

This is, of course, the most important issue, since the world today is on the threshold of a new era in lighting technology and we need to be sure that LED lighting is not harmful to health. To date (2014), this issue cannot be considered thoroughly studied, since the period of introduction of LED lighting into human life is still quite short and the necessary amount of statistical data for analysis has not yet been accumulated. However, at the moment there is a huge amount of facts and opinions of professionals in this field, indicating the absence of any harm from LED lighting. Moreover, it is believed that it is even useful. However, as always, there are few who are cautious in their assessments, or who claim the possible harm of LED lamps. However, there is no clear evidence of harm yet. Let's wait. On the other hand, there is interesting fact, that in many developed countries incandescent lamps have already been banned from production, fluorescent “energy-saving” lamps are on the verge of a ban or are simply not “promoted” or advertised. LED lighting has been given the green light and is being introduced everywhere. Below are generally accepted facts about the influence (or lack thereof) of LED lighting on humans.

Infrared and ultraviolet radiation

Infrared or thermal radiation in itself is harmless to humans. This is especially true for conventional incandescent lamps and is completely absent in LED lamps. With ultraviolet radiation it is more difficult. The most famous source of ultraviolet radiation is sunlight. Without going into details, we can say that this type of radiation is harmless in small quantities, but we all know how “excessive” sun affects the skin, so it is better to avoid this spectrum of radiation if possible. In this regard, LED lamps look preferable, since white light LEDs (household) with a color temperature of 3000-4000 (warm and neutral) and 5000-6500 (cool white) are deprived of the ultraviolet spectrum. Although, if necessary, using LEDs, you can achieve a wide variety of radiation spectra, including ultraviolet.

Radioactive elements and heavy metals

In this sense, incandescent and halogen lamps are safe for humans, unlike fluorescent lamps (they are often called energy-saving), which contain mercury vapor. If the seal of such a lamp is not broken, then it does not pose a danger, but if destroyed, mercury vapor can cause damage to the respiratory system, kidneys and other internal organs. With prolonged exposure to even relatively low concentrations (on the order of hundredths and thousandths of mg/m3), damage to the nervous system occurs, in some cases with death. It is for this reason that fluorescent lamps must be used very carefully and not allow the bulb to lose its seal. If they fail, such lamps must be disposed of in a special way, that is, they cannot simply be thrown into the trash.

LED lamps do not contain radioactive elements, and the content of heavy metals in the lamp microcircuits is no more than in an electronic alarm clock or radio and can only harm a person if they (the microcircuits) are consumed as food, and in large quantities. Thus, one more significant advantage of LED lamps can be recorded.

Heating of lamps, risk of burns

Even children know that you cannot touch a working incandescent lamp with your hands - you can get a severe skin burn. Moreover, the glass bulb of the lamp cools down slowly and if you do not wait 5-10 minutes after turning it off, you can get burned on a non-working lamp. Fluorescent lamps also heat up, but much less than incandescent lamps - their temperature on the surface of the bulb is about 50-60 degrees Celsius, that is, there is no fear of skin burns. LED lamps practically do not heat up during operation. A small amount of the heat they generate goes inside the lamp and is absorbed by special radiators. And in this case, LED lamps are a clear winner.

Presence of glass in the structure, danger of cuts

Everyone knows how carefully you need to handle incandescent lamps and energy-saving lamps. A fall even from a very small height leads to the destruction of the glass bulb of the lamp and the formation of a large number of fragments, which in itself already carries the danger of cuts. The situation is further complicated by the fact that the glass used in them is extremely thin, and the fragments are much sharper than those of a broken glass glass. LED lamps are much more durable in their design, since the bulb is made of unbreakable materials (plastic, polycarbonate, etc.).

The effect of flashing (pulsating) lamps

It is impossible to notice these ripples with the naked eye because they occur at a high frequency and are caused by fluctuations in the supplied voltage. The problem is that when such a high-frequency pulsation hits the retina of the eye, it is corrected and perceived by vision as an even light; however, it has been proven many times that these invisible pulsations are perceived by the brain and cause increased fatigue, headaches and poor health. Some studies also confirm the negative effect of pulsation on vision. This effect occurs in incandescent lamps and, to a much greater extent, in fluorescent lamps.

As you probably already guessed, LED lamps do not have this drawback, BUT with the correct design. U Low-quality LED lamps from unknown brands can be a threat to the eyes, the manufacturers of which save money and do not install special “drivers” in these lamps (you can read about them in the article about the design of an LED lamp), which prevent the lamp from flickering. Without a driver hidden in the lamp body, it will blink at a frequency of 100 times per second, which is impossible to notice, but poses a potential threat to the human nervous system. For this reason STRONGLY We recommend purchasing only high-quality LED lamps from well-known and trustworthy manufacturers.

Direct exposure of light rays to the eyes

Look at working incandescent lamps and energy-saving lamps not recommended, but they do not pose a great danger with short-term exposure of a few seconds. Even a short-term direct hit from a directed and very bright beam LEDs into the eyes - this may cause damage to the retina. Such direct contact must be avoided. Household LED lamps are always equipped with a special diffuser, which significantly reduces this risk, so the main attention should be paid to other household devices with relatively bright LEDs that do not have diffusers: flashlights, key rings, pointers, etc.

Positive effects of LED lighting

Research in the field of psychiatry notes that the soft and even light of LED lamps has a positive effect on a person’s emotional background, calms them down, and supports mental health. All office owners are recommended to switch to LED lighting - this will help increase the productivity of employees, reduce tension in the team, improve mood, and relieve eye fatigue.

A number of studies in the field of medicine show that LED lighting accelerates the regeneration of tissues and neurons, and therefore can be successfully used in the treatment and prevention of many diseases. After the discovery of this effect, a large number of new studies and experiments have begun in recent years in several specialized medical areas, and by 2015-2016 we may have much more information on this topic.

Researchers from Germany Andrei P. Sommer and Dan Zhu found that when exposed to intense light LED sources lighting, daily for several weeks, the skin becomes more elastic and looks younger, the complexion improves, and the depth of wrinkles is significantly reduced. Scientists have also elucidated the molecular basis for this effect of light. Protein molecules - elastin, which form the elastic basis of the skin, can be hydrated - covered with a kind of “film” of water molecules. Hydrated elastin fibers partially lose their elasticity, which leads to a decrease in skin elasticity. It turned out that high-intensity visible light emitted by LEDs penetrates the thickness of the skin and gradually splits off water from elastin fibers, restoring elasticity to the skin.

Articles about LED lighting

This article is for those who have asked a similar question for the first time and do not have a technical education. LED lighting is the lighting of something using relatively new light sources - LEDs. An LED is an industrially produced crystal that, when connected to electricity, begins to emit light. To be fair, LED cannot be called a new light source, because... it was invented several decades ago, but it began to be actively developed and used in all spheres of our lives only at the beginning of 2000, thanks to new discoveries in the technological field and a significant reduction in production costs.

Modern technologies do not stand still and scientific and technological progress does not ignore such an area of ​​our life as lighting. Development is taking place both in the direction of increasing lighting technical characteristics and in the direction of the emergence of additional related technological devices that increase the usefulness of lamps and lighting systems in general. We are talking about numerous varieties of LED lights with built-in sensors.

We decided to make a review in which the most interesting reviews about LED lamps will be collected. We collected these reviews both from our customers (and continue to collect) and from the Internet - from various forums, blogs, thematic portals and other resources. Having received a large amount of data, we systematized it, anonymized it, and we got a certain set of interesting opinions and advice from real people who use LED lamps at home, in the country, in the office, etc.

Customers of our online store often ask questions - which LED lamps are the best, from which companies? Why exactly are they better? Can you trust the characteristics of the lamps indicated on the packaging? Is it possible to buy LED lamps made in China? Can LED lamps be used in children's rooms? These are just some of the questions that buyers ask when choosing the best option for themselves. Moreover, such questions arise when the buyer already knows what type of lamps is needed and with what characteristics. In this article we will try to give answers to all these questions and avoid new puzzles for the consumer :-)

An LED is a semiconductor device that transforms electric current into light radiation. LED has a generally accepted abbreviation - LED (light-emitting diode), which literally translated into Russian means “light-emitting diode”. The LED consists of a semiconductor crystal (chip) on a substrate, a housing with contact leads and an optical system. The light emission directly comes from this crystal, and the color of the visible radiation depends on its material and various additives. As a rule, there is one crystal in the LED housing, but if it is necessary to increase the power of the LED or to emit different colors, several crystals can be installed.

This is, of course, the most important issue, since the world today is on the threshold of a new era in lighting technology and we need to be sure that LED lighting is not harmful to health. To date (2014), this issue cannot be considered thoroughly studied, since the period of introduction of LED lighting into human life is still quite short and the necessary amount of statistical data for analysis has not yet been accumulated. However, at the moment there is a huge amount of facts and opinions of professionals in this field, indicating the absence of any harm from LED lighting.

This article is for those who do not understand light bulbs, the types of their sockets and electricity in general, but already understand that using LED lamps is much more economically profitable than incandescent lamps and even than fluorescent lamps (they are often called “energy saving”). Selecting the right LED lamps is very simple and we will help you make the right choice by following the instructions below. Or you can call us right away and we will be happy to help you with your choice.

In this article we will talk about the benefits of using LED lamps compared to fluorescent (often called “energy saving”), halogen and incandescent lamps. In the second part we will provide an economic calculation of the payback when replacing lamps with LED ones. The economic efficiency of LED lamps is so obvious that you do not need any special knowledge to draw your own conclusions.

One of the challenges that is often encountered during deep renovation or construction of residential and office premises is the level of sufficient lighting. In a situation where ordinary incandescent lamps are used as light sources, from experience you can roughly determine the required number and power of light bulbs, but if you have an idea to make your home more modern and comfortable, and at the same time regularly save quite significant amounts on lighting, then It makes sense to take a closer look at LED lighting. So, how many and what kind of LED lamps do you need to install to make the room comfortable?

In one of our articles we talked about what an LED is and how it developed. Now we want to dwell in more detail on the current industry leaders - those who produce LEDs and LED lamps. This is not the same thing, since lamp manufacturers do not always make LEDs and, conversely, LED manufacturers do not always mass produce lamps based on them. According to official data from IMS Research, as of February 2013, LED production is concentrated in China (more than 50%), then Taiwan (about 20%), South Korea (about 10%), Japan, USA, Europe and other regions (total 20%) .

This article is a practical guide for those who are planning to make major renovations in an apartment or house and are thinking about how to make the lighting of their future home comfortable, cozy, unique, easy to maintain, but at the same time economical and environmentally friendly. Today, indeed, there is something to think about, since LED lighting is becoming very inexpensive. The choice of power, size and external design of light sources is very rich and you don’t have to limit your imagination. Where to start? How to approach the task correctly? To do this, you need to understand what exactly you want to do, and then find the most effective solutions from both a practical and economic point of view. It is not as difficult as it seems and we will be happy to help you with this.
