LED lamps "Feron": reviews, pros and cons of the manufacturer + best models

What lamps should not be bought?

Since there are not only successful samples in the Feron line, but also clearly bad ones, you should also know them. Although there are few such products.

LB-91.Although it is almost a complete analogue of the high-quality LB-92, the difference in accordance with the declared characteristics is huge.

So, its color rendering index is slightly higher than 74 units, which is just a mediocre indicator. This means that this lamp should not be used in residential premises. The only plus is that it doesn't flicker.

LB-72. This luminaire differs significantly from the characteristics indicated in Feron, but the main drawback is the ripple.

That is, LB-72 is capable of causing damage, and significant damage, to health if the owner is in a room that it illuminates for at least a few hours. What often happens on winter evenings. Therefore, it is better to refrain from purchasing this product for residential use.

The simplest test for all kinds of LED lamps can be performed using a regular pencil. If you hold it in the light flux and the silhouette begins to double, then the choice should be stopped on another product.

But due to the durability, sufficient reliability and low cost, the LB-72 can be purchased for use in garages, outbuildings, that is, where a person stays for a short time.

Briefly about the mysterious manufacturer

Products with the logos of this company have been known to us for a long time and are even popular. But very little is known about the manufacturer itself, and all that catches your eye is the 1999 year of foundation. In addition, Feron products came to the post-Soviet territory in 2004.

And it is also clear that all LED lamps are made in China, their developers are also located there.

There are suggestions that the presented company is only a customer, and manufacturing is carried out at the sites of third-party manufacturers, and different ones, which often directly affects the quality of products.

Feron is not a top manufacturer of LED lamps, but is able to provide users with inexpensive and relatively high-quality products. Which, thanks to this, has become popular in almost the entire post-Soviet space

Despite all the secrecy, such lamps are in demand, and the brand itself has reached the sales levels of its most famous competitors. Among which are popular names all over the world.

Numerous reviews from the owners of products manufactured under this brand, in most cases, indicate that it is of decent quality, therefore it can serve for years even in difficult conditions.

Although over time, signs of degradation appear, namely, the brightness of the glow decreases, the color rendition changes. Although such negative features are inherent in all LED lamps without exception.

Also, users indicate that the marriage rate is quite low. And if, nevertheless, the purchased lamp did not work out the stated warranty period, then it can be replaced without unnecessary difficulties at the point of sale that served the person.

Overview of popular models

The quality, and hence the reliability and durability of LED light sources is directly related to the manufacturer. OSRAM, FERON, GAUSS, CAMELION, NAVIGATOR, SAMSUNG, PHILLIPS, UNIEL are considered bona fide manufacturers. Bulbs of these brands cost more, but the quality justifies the price. The products of SKYLARK, ECOLA, JAZZWAY are cheaper, but also have a good reputation among consumers.

Unfortunately, the reliability of LED lamps depends on the quality of the assembly and the LED elements themselves. Sometimes lamps of the same manufacturer, assembled at different factories, differ from each other.

Overview of the budget LED lamp Feron LB-70

We test an inexpensive Feron LED candle lamp on 6 SMD 5730 LEDs with a white luminous flux, install it in a wall lamp and a refrigerator.

There was trouble with the refrigerator, the backlight burned out and melted the ceiling that covered it, there was a regular 15 watt with an E14 base. Since the wife demanded that the lighting be restored, the led corn with the E14 base was removed from the chandelier, but the appearance of the chandelier immediately suffered and the corn had to be returned to its place.

The dimensions of the light bulb were small compared to the corn, but thanks to the elongated shape, it fit in the place of the previous one.

There were also thoughts of sticking a strip of LED strip on the wall inside and powering it through a small driver, but there was nothing suitable at hand.

Characteristics of Feron

Technical characteristics of Feron

• number of LEDs 6;
• color temperature 4000K;
• stream of light 300 Lumen;
• current consumption 25 mA;
• case is transparent;
• the service life was written 10.000 hours, but the box says 50.000 hours;
• price 110 rubles on January 21, 2015.

The specifications of the Feron LB-70 were perfect for my needs, so I bought 2 pieces.

Feron for 110 rubles.

Testing

Refrigerator lamp

The sweetheart climbed into the place of the old lamp, as expected, but naturally it sticks out significantly due to its large length, so the ceiling will not fall into place.

Brightness in the evening

The luminous flux is an honest 300 Lumens, I can determine this quite accurately by eye, or by comparing corn, which I have been using for 5 years. In terms of dimensions, I can say that SMD 5730 LEDs are installed, the luminous flux of each is approximately 50 Lm according to the passport, respectively, 6 LEDs shine at 300 Lm.

In addition, I was surprised that at such an inexpensive price, flicker is completely absent, that is, the ripple coefficient is almost zero.A full-fledged driver is installed inside, and not a ballast capacitor with a diode bridge.

She is completely free of flicker, as can be seen from the photo

Before scratching the lamp, I thought that it was plastic and wanted to break the bulb with gentle blows, and it’s good that it didn’t break.

Before buying, pay attention to this, it was not written anywhere, and the glass bulb may not correspond to your operating conditions, especially if there are children in the house

Power consumption

Power consumption

The power consumption of the LED lamp corresponds to that stated in the technical specifications, and is equal to 3.4 watts, the measurements were carried out with a fairly accurate household wattmeter. After an hour of work, the base heated up to 52 degrees, during further work the temperature did not exceed this value.

Why LED lamps flash: causes and solutions

Some consumers, having installed LED lamps in the house, notice that their operation is accompanied by flickering. Such lighting tires the eyes and harms vision in general. Having understood the reasons for such a negative effect, one can find ways to fix it.

Why do LED lights blink when on?

There are several reasons why LED lamps blink when on. Why is this happening:

• incorrect installation - it is necessary to check all the contacts of the circuit, they must be strong;
• adapter power mismatch with the lamp used - you can replace the power supply with a new one that matches the power;
• significant power surges - the driver may not be able to cope with surges, the level of which is beyond the permissible;

LED lamps are able to work without problems with power surges

• defective product during production - it is necessary to replace the light bulb, since this product is accompanied by a guarantee;
• illuminated switch - it is not recommended to use such switches in conjunction with an LED light source, since when such a device is turned off, the circuit is in a closed state and contributes to the glare of the lamp;
• wire connection mismatch - the “zero” phase should be output to the lighting device, and the wire with the phase to the switch;
• the presence of household electrical appliances that create high-frequency interference;
• the life of the LED lamp has expired.

But many people also face another problem when LED lamps glow after being turned off. You can find out why this happens by familiarizing yourself with the functional features of led lamps.

Why do LED lamps blink or glow when the light is off?

The reason why the LED lamp is on when the switch is off or flickering intermittently may be a switch with an LED light. If you replace the illuminated appliance with a conventional switch, the lamp should stop flashing.

Spectrum of different light sources

The fact is that in the off state, the electrical installation device does not completely open the circuit: the main supply of electricity stops, and the backlight LED closes the circuit. The current passing through the diode charges the driver capacitor of the LED lamp, as a result of which it either blinks or emits a dim light.

Another reason why the LED lamp is on when the light is off is a poor-quality product. If you purchased an LED lamp at a low price and the manufacturer is unknown, it is likely that low-power components are installed in such a device.Light sources offered by leading manufacturers usually use capacitive capacitors. Of course, their cost is high, but they do not blink even when paired with a switch with LED backlight.

Why do LED bulbs burn out

The main reasons for the failure of LED light sources are poor product quality or external influences. The latter include:

a significant excess of the supply voltage - if there are power surges in the mains, you should give preference to models designed for 240V or more. You can also resort to the use of protective blocks and rectifiers;

To avoid problems, it is best to choose products from trusted manufacturers.

• poor-quality lampholders - poor-quality material of the cartridges tends to break down when overheated, the contacts are oxidized, thereby creating even more heating of the LED lamp base;
• the use of powerful lamps in closed-type plafonds that are not intended for the use of powerful light sources;
• use of the mode of frequent on-off of LED lamps - the working life of the lamps is noticeably reduced;
• incorrect connection diagram - if one lamp fails, the malfunction is transmitted to other light sources in the common circuit;
• poor-quality connection of wires at the nodal points of the electrical network - when connecting, it is recommended to use terminals, soldering or other modern connection options.

Every year the price of LED lamps is getting lower.

How to choose an LED light bulb

When choosing an LED lamp, you should pay attention to the following parameters:

1. Actual or equivalent power;
2. Light flow;
3. Colorful temperature;
4. Color rendering index;
5. Ripple factor.

LED lamp power may be defined in fact or equivalently. The first parameter shows how much electricity the device consumes. It can be very small - literally 6-10 watts, but this should not be embarrassing. Because LEDs consume a minimum of electricity. So, a 6-watt LED lamp shines as brightly as a 40-watt incandescent lamp; and a 10-watt LED is like a 60-watt incandescent.

Actually, it is this parameter that can be indicated on the package - “equivalent to a 40 W incandescent lamp”, “equivalent to a 60 W incandescent lamp”.

Light flow - a parameter that determines the brightness of the light bulb. More objective than actual or equivalent power. LED bulbs with a flux of 400 lm are similar in brightness to 40-watt incandescent lamps, 600 lm - to 60-watt, and 1000 lm - to 100-watt.

Colorful temperature - a parameter that describes whether the lamp will shine with warm or cold light. So:

1. Up to 2800 K - “warm yellow”, like old incandescent lamps;
2. About 3000 K - "warm white", like modern incandescent lamps;
3. About 4000 K - "neutral white", for kitchens and office space;
4. About 5000 K - "cold white", for utility rooms. In a house with such a lamp it will be uncomfortable, and it causes a strong strain on the eyes.

Color rendering index - an important parameter that determines how much light from a light bulb will affect the shades of surrounding objects. It is denoted by the characteristics CRI or Ra. It is recommended that the color rendering index be at least 80, and preferably 90 or higher.

A low color rendering index will cause objects around you to appear gray or unnaturally yellow, which affects not only the mood, but also the overall level of comfort in the room.

The ripple coefficient shows the uniformity of the glow. For most good LED lamps, it is about 5%. If the ripple factor is more than 35%, it is better not to use such a lamp - it will lead to a serious strain on the eyes.

Other characteristics do not have a special effect on operational parameters. Therefore, they can not be considered - well, or choose LED bulbs based on your wishes and requirements.

How to choose a Feron lighting fixture?

In order not to become a participant in the lottery upon purchase, you should initially read the reviews, the results of independent tests.

But often there is a minimum of information about Feron products, especially when the release of a model has just begun. And to avoid an unsuccessful purchase, you can check it yourself. Why should you take your smartphone with you to the store?

The fact is that pulsation can be easily detected with a camera. Why you only need to look through it at a working product. If there are no flickers, then the test is passed, and if interference is visible, then it is better to refuse the purchase.

Nevertheless, Feron is a reliable supplier, so all products are provided with a long warranty. And you can exchange the lamps at the same point where the purchase was made

10 Jazzway

Shockproof body. Dimmable LED lamps
Country: Russia (produced in China)
Rating (2018): 4.0

Jazzway trademark, which offers LED products, announced itself on the domestic market in 2008. Currently, the range of the company includes over 1,500 items of goods. A significant place in the catalog is dedicated to dimmable LED lamps ("DIM"), which are suitable for creating soft and dimmed light with the ability to control the level of illumination.

The branded line "Power" offers high power LED lamps combined with maximum luminous flux, and the "Eco" collection - low-cost LED lamps. Special attention deserves a series of energy-saving lamps with a filamentous emitter, acting as an analogue of traditional incandescent lamps. The highlight of the range - special LED lamps for refrigerators, plants, balconies and terraces

The reviews emphasize that all the lamps are enclosed in a strong shockproof case, do not flicker, give an even light, heat up slightly, and, importantly, do not hit the pocket

Overview of the main disadvantages

Each buyer needs to be prepared for the fact that most Feron lamp models do not meet the main declared characteristics, and significantly.

For example, often the power and brightness are a quarter less than indicated on the box and base. Bypassing any such marketing ploy is easy - you need to purchase a more powerful model, but you will have to pay more.

The color rendering index also meets the standards for only a part of the products. What happens as an unpleasant surprise is that the transmitted color may differ significantly from the expected result.

In some cases, the accuracy of this parameter does not exceed 75 units.This means that not all colors of the illuminated objects will be transmitted correctly. And although the indicated index corresponds to the “good” rating, lamps with this characteristic should not be used at home.

The advantages of the manufacturer include the ability to choose an LED bulb in any case, and inexpensive, for example, for a table lamp

In addition, individual representatives of the Feron product line can pulsate, which is considered one of the main disadvantages in the field of lighting technology.

This phenomenon can significantly affect human health, namely:

• eyes get tired much faster;
• irritability appears;
• varying degrees of headaches;
• partial loss of performance.

The listed negative points are caused by an insufficiently stable electric current, which the equipment of LED lamps cannot stabilize to the desired parameters. That is, the pulsation additionally indicates the mediocre quality of individual Feron products.

And yet such a disadvantage is the cause of flashing when the switch is off, equipped with a backlight. And this is a common disadvantage.

As a result, a person will have to immediately change the purchased lamp to another model or upgrade it by replacing the driver or smoothing capacitor with a new one. Although such procedures are not financially burdensome and are carried out quickly, but who will be pleased with them?

For the sake of objectivity, you should know that pulsation occurs only in individual models. But still, there is no guarantee that the choice will not fall on her.

Customers need to be aware that Feron LED lamps have different color rendering, so they can well enhance the aesthetic properties of any interior. The main thing is to make the right choice

For example, LB-92 lamps and almost its analogue LB-91 are in traditional demand. At the same time, the first one practically corresponds to the declared characteristics, and in addition, it is distinguished by durability, lack of pulsation.

But the second one is significantly inferior to it, and in all respects. But it is difficult for an outsider to distinguish them, since the markings are similar, and outwardly both varieties are generally identical.

This leads to the conclusion that the choice of LED lamps must be approached competently, having certain knowledge. And when buying, be sure to check them for the absence of pulsation, which is easy to do even without special equipment.

And this is another drawback, since the products of leading companies, for example, the Dutch Philips, do not have to be bought with such difficulties. Because it has an extremely low percentage of defects, stability of characteristics, but it also costs more.

Lists of the best

Above, we have presented you with a rating of the TOP 7 energy-saving lamps according to their characteristics and price. Now I would like to highlight the best in these categories:

• Halogen.
• Luminescent.
• LEDs.

Let's talk about another type of light bulbs - halogen lamps. They were created to replace incandescent lamps, and are distinguished by a high luminous flux. Their light is much brighter, and the service life is several times longer than that of conventional light bulbs. They have a standard base and are suitable for conventional cartridges. Halogen incandescent lamps consist of a bulb filled with gas (bromine or iodine) and a base. Flasks may vary in size. Usually they are used in car headlights or in lighting devices that require high brightness.

Halogen – Uniel led-a60 12w/ww/e27/fr plp01wh

Rating of the best LED lamps for the home

Let's start the review with the leader among these models, taking into account the characteristics of the product and customer reviews.“The Gauss company offers high-quality and efficient lighting equipment. This brand is superior in many respects to its competitors. Among the main advantages: a seven-year product warranty, 50,000 working life (in hours), aluminum radiators, original design. The range includes dimmable, capsule, soffit, mirror and standard modifications. Among more than 170 items, there are LEDs with a beam angle of 360°.

The quality of products is largely due to the automation of the entire production process, as well as careful control at each stage. The responses of customers note the packaging, which is made of thick laminated cardboard, with a reliable lamp retainer, which eliminates moisture and mechanical damage. It contains all the necessary information to help you choose the right light element.

Plinth g9 - description, dimensions

Historically, the pin base was introduced in the second half of the 20th century, when it was necessary to create miniature light sources. The reduction in the size of the flasks has led to the appearance of pin bases other than screw bases. This design made it possible to further reduce the size of light sources, reduce the amount of materials for manufacturing.

Over time, the pin type g became widespread, second only to the screw type. The pin base is designated by the letter g and a number. G9 means that the distance between the contact centers is 9mm.

Pin contacts are made of different materials: ceramics, glass, plastic. The material depends on the type of light source and its heating during operation. The hotter the light bulb heats up, the more thermally stable the base should be.For example, for halogen lamps, the operating temperature reaches 300⁰С. The base for them is made only of glass or ceramics. The LED light source glows slightly (up to a maximum of 70⁰С). Plastic can withstand this heat.

Also, depending on the type, the shape of the steel contacts is slightly different: for "halogens" these are loops, and for led - petals.

Plinth options g9

For fastening use a special cartridge.

Cartridge

The difference between a g9 LED lamp and a g9 halogen lamp

Please note that some models of g9 LED lamps have an insulating plastic housing that is somewhat wider than the length between the contacts of the g9 base, as a result of which the lamp does not fit into some fixtures. To connect this lamp to the cartridge, you must use a file and remove the excess body width

The design of the plafond is protected from moisture and dust. The plafond is fixed in the luminaire with screws or threads. Depending on the operating conditions, it is made of ceramic or plastic. Ceramic is not subject to short circuits, does not crack from heating. Such a ceiling is best installed in lamps that work for a long time. The plastic cover is suitable for led, it is lightweight, it will not break when dropped.

Compared with the screw pin g9 is hermetic, versatile. If desired, a lamp with g9 can be inserted into any lamp: you just need to buy a special adapter.

Disadvantages and disadvantages of LEDs, as well as lamps assembled on them

The main and main drawback is the warranty. The guarantee is not only for LEDs, but for light sources assembled on their basis. Each lamp manufacturer, in pursuit of its buyer, offers a guarantee for the uninterrupted operation of its products for 3-5 years.Here it is worth considering ... Why so few? After all, the service life of the diodes themselves is an order of magnitude higher !!! The answer is simple. Any lamp is not only LEDs. This is a complex device that contains numerous electronic components. It is they who fail before the diodes. So, if the warranty of your lamp is 3 years. and it broke after three years and one day, then with a high probability you will be left without a lamp and without money. And that means you won’t get a “fat plus” in the form of energy savings. The average payback period for a good light source is at least 5 years. It's not pleasant, but tolerable. Especially if you give preference not to cheap fakes, but to high-quality lamps from famous manufacturers.

The first and most important drawback is pulsation

1The most annoying problem with LED lamps is flickering. High-frequency flickering, pulsation. This is the scourge of today's lamps. A more detailed description of this problem will be discussed in one of the following articles.

In the meantime, let's take into account that ripple is the main drawback of LED lamps. Often Chinese lamps suffer from it, in which capacitors are used instead of drivers.

And if you take into account the advantages and disadvantages of LEDs (any), then this criterion often plays a role in refusing to buy LEDs, since many do not know how to deal with pulsation, flickering of LED lamps and diodes directly.

The high price of chips

2The cost of LEDs and lamps. This characteristic has remained and will be relevant for Russian buyers for a long time. For high-quality and expensive LEDs from eminent Nichia, Philips, Osram, the prices are simply “ahovskiye”. But you want cheap and beautiful))) But in this aspect, this is not suitable. In LED lighting, cheap is never good. Not that market.

I spent a lot of time assembling various LED derivatives. And as expected, I bought a large number of chips on the well-known Aliexpress site. Everything seemed to suit. Cheap and cheerful. But at that moment I was young and green in LED lighting. Somehow I got into herb diodes from Nichia ... There was no limit to surprise. With a similar power of light, I received almost three times more than Chinese ones. This prompted me to mentally reflect on the advisability of buying Chinese components. But I didn’t have enough for a long time) I had to look for the “golden mean” again on Ali. Only after a long painful search did I manage to find suppliers who sell fairly high-quality diodes for quite a tolerable price. Not much worse than the famous ones. If you are interested, write, I will give a link. Not cheap. But qualitatively. Small difference. Advantages and disadvantages in such LEDs will suit everyone.

Driver

3Earlier, I already announced that all diode lamps have a driver in their composition. The higher the quality of the power supply, the more expensive the final cost of the product will be ... I will also attribute this to the minuses and disadvantages of LEDs. I would like it to be cheaper.

Dimming, beam angle and color temperature

4Dimming. It can also be attributed to the cost. Any LED lamps do not work with dimmers from incandescent lamps. And this means you need to buy a new dimmer, and the lamp itself, which supports dimming, is also not cheap. Again minus karma.

5Small angle of dispersion. Diodes emit light in a narrow direction. In order to get more or less normal light, you have to use secondary optics. Lamps without lenses and collimators look less than respectable. Again costs ... Again an increase in cost (.

6. LED bulbs are available in various color temperatures. For an apartment, you can select from 3500 to 7000K. Without a clear understanding, it is not possible to choose a lamp of the desired glow for an inexperienced buyer. And most manufacturers do not always correctly indicate the temperature.

7. And one more interesting observation. Buying in two stores for an incandescent lamp, we get a “flask” identical in light. In the case of LEDs and LED lamps, this will not work. In nature, there are no identical diode lamps. Therefore, two lamps bought in different stores of the same glow and power will most likely shine differently. Of course, if it happens that the lamps are assembled on diodes of the same brand and released at the same time, then the distortion will be minimal. But then again, this is from the realm of fantasy. Who does not believe. Can try. ) As you know, smart learns from the mistakes of others. I didn’t have examples, I checked))) The light show is still something!)
