LED lamp tests. Big test: LED lamps. Of course, these are not all good lamps

In the consumer-state relationship, there is a tireless game of cat and mouse. First, hot water became more expensive, and the population rushed to install electric boilers. Accordingly, the state decided to radically increase the cost of electricity, and at the same time cold water. The reasons that officials come up with to justify the constant increase in tariffs are, to put it mildly, designed for gullible people, therefore “saving drowning people is the work of the drowning people themselves.”

One of the ways to save your own budget is to completely switch to energy-saving technologies, including using only LED light bulbs for home lighting. But how can you be sure that the savings are real?

The requirements set by the state for the quality of LED lamps are specified in the document "Resolution of the Cabinet of Ministers No. 992 dated 10/15/2012 About the approval of LED lighting devices and electric lamps that are subject to inspection within the limits of Another source using the method of clarification" (hereinafter referred to as Resolution 992), which, although not a legacy of the USSR, is still morally outdated, since technologies are developing much faster than the laws governing them are written.

TESTING
In the current test there are 28 LED lamps with E14 and E27 sockets. All details are shown in the comparison table.

To make the terms and characteristics used on the labeling of light bulbs and, of course, in our testing clear and accessible, it is necessary to make a short overview of lighting technical terms. We will not explain too abstrusely and will start from the very beginning, i.e. from those characteristics that a potential buyer first notices.

Having collected some of the most common questions regarding the use of energy-saving and LED lamps, we have compiled a section “Lamps in questions and answers” ​​(at the end of this text...).

Power. Measured in Watts (written as W or W). The higher the power, the greater the energy consumption. The standards have a limit on the excess (+15% is allowed), but there is no limit on the lower limit. This is due to the fact that if the manufacturer was able to produce the same luminous flux at lower power, then this is even good for the consumer. But a good manufacturer will still indicate the power as close to reality as possible.

In light-emitting diode lamps (LED), there is practically no longer a “standardized” power to which manufacturers were tied, so there are very unusual ones - 4.5 W, 8 W, etc. This is due to the fact that a special organization for regulation and development of standards LED sources light Zhaga (www.zhagastandard.org) came to the decision that, taking into account the rapid development of LED lamps and the constant change in their characteristics for the better, it is necessary to regulate and rely not on power, but on the luminous flux. Thus, the main parameter is the level of luminous flux, not power.

Light flow. Measured in lumens (lm or Lm). This is probably the most important and responsible indicator of the lamp. As a matter of fact, they mean how light it will be in your room, i.e. how much light will “escape” from the lamp to the outside. The higher the number, the lighter it will be. It has a “bad habit” of decreasing over time of use.

As you can see on the packaging of the light bulbs, almost all manufacturers indicate that their lamps correspond to similar incandescent lamps. This is the practice everywhere in the world, but in order not to mislead consumers, the EU has developed the EU Ecodesign DIM2 directive, which stipulates.

In this Directive, when specifying the required luminous fluxes, the duration of combustion with loss of flux level is taken into account. Accordingly, the more long term combustion is promised by a lamp (for example, LED), the greater the luminous flux it should initially have.

When comparing the measurement results with the data in the table below from the Directive, it turned out that a significant part of the tested lamps DO NOT CONFORM to the declared analogy ()

Colorful temperature. It is measured in kelvins (written as K). The color indicator of the lamp, i.e. the shade of light that the lamp emits (yellowish, white, bluish). The most common three groups of color temperatures are:

• Warm color - “like a regular incandescent lamp” (color temperature, approximately 2700-3300 K); This is the color of the sky at sunset;
• Daytime color - (4000-4200 K), ordinary white color without tint; this is the color of a dim, diffused sky;
• Cold color (about 5000 K); bluish-white color;

By the way, a bright, pretty blue sky has a temperature of about 30,000 K, which means that the higher the temperature, the greater the transition to a blue tint, the lower - to red.

Here the manufacturers' imagination runs wild. The same color is called “soft neutral” by some, “cold” by others, “bright” by others, and “natural, daytime, neutral” by others.

Basement. The most common types of screw bases at home are E14 (the so-called minion) and E27. The indicated numbers mean millimeters of the diameter of this base. This type of base is also called the “Edison base”.

Light output. This is a set of indicators that can be called a coefficient useful action(but is not such), in particular the ratio of luminous flux to power. Displayed in lm/W. The higher the luminous efficiency value, the more economical the light bulb is. This figure would be a better guide if manufacturers always wrote the truth.

The theoretically achieved maximum value for complete conversion of energy into visible light for white light is 199 lm/W. A conventional incandescent lamp has a low luminous efficiency - a little more than 10 lm/W, which is its main disadvantage.

Color rendering index (denoted as Ra or CRI). In simple words, it means how well our eyes will perceive the colors of objects that we see in artificial light. The better the lamp light illuminates objects, the better the human eye will distinguish between their colors and shades. The standard is considered to be sunlight (100). The numbers in the lamps should be at least 70, but there are nuances here. In the EU, the norm is at least 80, and values ​​​​less than this figure can be used for street or industrial lighting. In Ukraine, according to the Resolution of the Cabinet of Ministers, the standards specified are 70 for indoor lighting and 60 for outdoor lighting. The color rendering index is of great importance when lighting any premises where accurate determination of color is important: artists’ and fashion designers’ workshops, darkrooms, fitting rooms and, especially, children’s rooms, because the better it is (and higher), the better the child’s brain will determine real colors in the future will perceive them correctly.

In testing, we analyzed a special parameter: a special color rendering index (R 9). An interesting indicator. In general, color rendering indices reflect how realistically we see the colors of objects, so R 9 is interesting because it shows how well we will see rich red color. As well as the quality characteristics of the LEDs themselves used in the lamps. By the way, a very important indicator for illuminating operating rooms.

But in general, discussions and attempts to achieve uniform standards in color rendition designations, so that they reflect real quality characteristics, are still ongoing.

Pulsation coefficient (KP, %). As a matter of fact, this is the same flicker that we can see in low-quality or old tubular lamps. Such flickering not only tires, but can also stimulate deterioration of vision and well-being, and can even provoke an attack of epilepsy.

Brightness (light intensity). It is measured in candelas (written as cd or cd). Not found on household light bulbs, since it describes the amount of light distributed in a given direction, while consumer lamps, as a rule, shine in all directions. The brightness data should be on the so-called The higher the number, the brighter, but also a bit harsh for the eyes.

Illumination. It is measured in lux (lux or lux). It is not directly related to the technical indicators of the lamps; it relates to the level of illumination of the place, i.e. how the same lamps illuminate, for example, a school classroom or room.

Labeling and Packaging
There were no comments about the packaging this time; the lamps were packed in cardboard. All flasks are plastic, i.e. not as fragile as incandescent or fluorescent lamps.

There are some comments regarding the labeling, although there are much fewer of them than in our previous tests. There were no such obvious violations, such as not indicating the luminous flux, this time.

The rating for the Osram lamp was reduced for discrepancies in the power data on the packaging. In one place the power is indicated as 9 W, in another as 9.5. There are also differences in the warranty period, 2 and 3 years, respectively.

The marks were reduced for misleading the consumer regarding the manufacturer as the country of origin. All lamps in testing were made in China, and there is no need to indicate the manufacturer as an EU country or Ukraine.

Also, the rating for E-stars lamps was reduced by one point for the lack of compliance with similar incandescent lamps indicated on the packaging. This is an optional item from a regulatory perspective, but since not all consumers know what to expect from a 6W lamp, we believe it is very important.

Technical tests
Light flow. First of all, the quality of a lamp is determined by the luminous flux. This value shows the total amount of light emitted by a given source. All lamps are required to indicate this value on their labeling. And this time everyone did it, although in most cases they did not correspond to reality, but that’s another conversation.

Firstly, it is necessary to explain how deviations in the level of luminous flux were assessed and, accordingly, how this affected the estimates. Both in EU standards and in Ukrainian, a loss of luminous flux of 30% is accepted as such, that the lamp is actually considered inoperative (although, of course, it can still burn). With our five-point scale, we divided 30% into grades and found that for every 6% deviation downward, the grade decreases by 1 point. For example, the Eurolampturbo lamp (e27) stated a luminous flux of 700 lm, but actually has 461 lm, which is 34% lower. Accordingly, the rating for such an indicator can only be “very bad”.

Unfortunately, there are quite a lot of deviations in this most important parameter of light bulbs. Ratings were reduced to varying degrees: Electrum (e14), Feron (both types), Gauss (both types), Videx (e14), Emilight (e27), Eurolamp (all 3 positions), "Online" (e27) and Jazzway ( e14). See the comparison table for more details.

Colorful temperature. There are standards for the permissible deviation of color temperature in one direction or the other. In our testing, FeronOptima (both types), Gauss (both types) and JazzWay (E14) lamps deviated from the required parameters, which certainly reduces the quality rating.

Power is a familiar, but no longer so important, characteristic of household lamps. All lamps had a power slightly lower than declared, which is quite acceptable; moreover, if the luminous flux corresponds to the declared one, then it’s completely good.

Color rendering index (Ra or CRI). In Ukraine, existing standards indicate 70 and 60 for indoor and outdoor lighting. In the EU, the standard for indoor lighting is 80. Based on the color rendering parameter itself (i.e., the more, the better), we decided that the ratings here will be given based on the manufacturer’s self-declaration (no less than what he himself stated), this is how it should be no less than 80.

Here the ratings were reduced by ELM (both types, less than 80), Videx (both types, less than declared), Svetkomplekt (e27, less than declared), Gauss (both types, less than declared), Eurolamp (all 3 positions, less than declared).

We did not reduce the ratings for the special color rendering index; it is recommended and promising for understanding. Moreover, none of the manufacturers indicate it on the packaging.

Pulsation of light. As we all understand, pulsating light will irritate the eyes. The level of pulsation is standardized depending on the type of premises and is regulated (in our opinion, very specifically) by building codes (DBN). As a rule, the numbers are in the range of 10-20%. Fortunately, in testing only the Navigator (e14) and Emilight (e27) lamps have clearly overestimated pulsation figures - 38% and 75%, respectively, which leads to lower ratings. The rest either have no pulsation (the specificity of the device that determines pulsation is that it does not allow you to show the figure 0%, so 1% means that there is practically no pulsation), or much lower than visible.

Economic characteristics
Compliance with incandescent lamps. Given the available compliance data for incandescent lamps, we decided to include this indicator in the estimates. For deviations of more than 10 W, the rating was reduced. Moreover, consumers often focus on power rather than luminous flux, and such data is very clear to them.

It is important to clarify and remind consumers (and it seems like most manufacturers) that there is no “nice proportional relationship” between power and luminous flux. Therefore, equivalent inscriptions on compact fluorescent lamps(CFL) up to 5 times and LED up to 10 times are not true. In order for the consumer to have an idea of ​​what equivalents exist, the EU has created the EU Ecodesign DIM2 document, which provides comparable data on luminous fluxes different types lamps in relation to incandescent lamps (link). For example, a Eurolamp (e27) lamp with a power of 10 W is stated as an analogue of a 100 W incandescent lamp, which is not true, since the luminous flux of a 100 W incandescent lamp is 1340 lm. And with Eurolamp, even the declared one is only 1000, but in fact it is generally 801 lm, which is only suitable for a 60 W lamp.

Inconsistencies in this indicator led to lower ratings for lamps: Electrum, ELM, Videx, Svetkomplekt, Feron, Eurolamp, Gauss and “Onlight”.

Luminous output- a value that shows how efficiently consumed power is converted into light. This term refers exclusively to light bulbs; it is a kind of indicator of energy efficiency (not efficiency, although it is very similar), and is expressed not in %, but in lm/W.

Previously there were no requirements in the regulations, but now there are. Thus, from July 1, 2014, in lamps with a temperature of 2700-3500K, the luminous efficiency must be at least 70 lm/W, with a temperature of 4000-5000K - 80 lm/W, and with a temperature of 5700-6500K - 90 lm/W.

We calculated this indicator based on the actual data received, and not on the declared ones. With current standards, there are no comments on the results obtained.

Good to know!
Bad news: We were unable to verify such an important indicator as operating life during laboratory tests, since this would have required decades; Therefore, you will have to check the honesty of manufacturers in this matter yourself.

Good news: As a rule, LED lamps have a fairly large guarantee period, so you can replace the burnt-out light fixture with a new one if you do not lose the receipt and packaging. Therefore, do not throw away the receipts and make a note for yourself of where the receipt is and from which lamp.

Price and quality

Despite the large number of bad ratings and a lot of comments on the actual performance of the tested lamps, there is still some good news. Firstly, the overall quality of light bulbs is gradually improving. Of the 28 positions in testing, 10 have an overall rating of excellent and another 4 are good. Those. almost half. Secondly, the leaders who did not let consumers down before remain so. They were joined by some "newbies" who, we hope, will not worsen their grades in the future. The following brands are rated “excellent”: E-stares (both types), JazzWay (e27), Maxus (both types), Osram (both types), Philips (both types) and Svetkomplekt (e14). Rated “good”: Electrum (e27), ELM (e14), VidexE-series (e27), Svetkomplekt (e27). Thirdly, prices for LED products have decreased significantly compared to previous tests. Replacing all the lamps in the house leads to a very significant reduction in energy consumption and, as a result, a change in bills. As for lamps rated “bad” and “very bad,” we think they should also be listed here: Eurolamp (all 3 positions) - for discrepancy in luminous flux, similarity to incandescent lamps and color rendition. EMILIGHT (e27) - for discrepancy in luminous flux and crazy pulsation (75%). FeronOptima (e27) - for discrepancy between luminous flux, color temperature and similarity to incandescent lamps. Online (e27) - for the discrepancy between the luminous flux and the similarity to incandescent lamps. Gauss (e14) - for discrepancy between luminous flux, color temperature, color rendering and similarity to incandescent lamps. JazzWay (e14) - for discrepancy between luminous flux and color temperature.

Lamps in questions and answers

How consistent is the indicated ratio of similarity of lamps, such as “20 W corresponds to 100 W”?

This ratio is, in principle, incorrect, since it makes sense to compare not the power, but the level of luminous flux. But CFL and LED lamps do not directly correspond to this comparison. Only halogen lamps(see material on ratios and comparisons of different types of lamps...).

Why do some lamps flicker even when turned off?
This occurs due to a small current leakage into the lamp itself, most often when using an illuminated switch. Inside such lamps there are capacitors that allow the combustion to start; the current leakage is enough to “work”, but not enough to maintain it. Therefore, the lamps light up and immediately go out, in other words, they blink. And while in CFLs this may be hardly noticeable, because they take time to burn up, then LEDs flash very convincingly.

But some lamps already indicate on the label the possibility of using them on backlit switches, respectively. no blinking.

Why do the new LED lamps have such strange power?
This is due to the fact that a special organization for regulating and developing standards for LED light sources, Zhaga (www.zhagastandard.org), came to the decision that, given the rapid development of LED lamps and the constant change in their characteristics for the better, it is necessary to regulate and build on from power, but from luminous flux. Thus, the main parameter is the level of luminous flux, and not its power.

Is it possible to install such lamps outdoors?
It is possible, but only in protected cases, i.e. not just open. The operating conditions indicated on the markings allow their operation in winter conditions down to -20 0 C.

What CFL and LED lamps do not like is hermetically sealed housings and high humidity. This is important when installing, for example, in cellars, swimming pools or saunas.

Can energy-saving and LED lamps be used in light controllers and timers?
Energy saving lamps (CFLs), as a rule, do not. LED lamps can be used without restrictions with timers and motion sensors, but only lamps that have a special designation on the packaging - a circle with an arrow inside - support luminous flux control.

Most of the LED lamps that I test and write about can only be bought in specialized online stores, but ordinary buyers usually buy lamps in hypermarkets. I went to Auchan and Leroy Merlin stores, bought 48 models of LED lamps there and tested them. I returned the lamps back to the stores, as they have a return option. Today - 22 lamps from Auchan.

As you can see, quite a few lamps turned out to be bad. First of all, they have a high pulsation (flicker) of light. I consider all lamps with a pulsation level of more than 45% to be substandard. Such flickering is visible visually and is located in a room illuminated by lamps.

As you can see, quite a few lamps turned out to be bad. First of all, they have a high pulsation (flicker) of light. I consider all lamps with a pulsation level of more than 45% substandard. Such flickering is visible visually and being in a room illuminated by lamps with high pulsation is very uncomfortable.

None of the tested lamps provides the luminous flux promised by the manufacturer and only two lamps have a luminous flux of 99% and 97% of the promised one, which fits into the requirements of GOST R 54815-2011, according to which the measured initial luminous flux of an LED lamp must be at least 90% of rated luminous flux. These are Osram LED Star PAR16 35 35 AA74222 GU10 and Vitoone 1510590 Bulb lamps, which fall into the good group. The remaining 20 lamps have a luminous flux of 61-88% of the nominal and do not comply with GOST.

9 lamps have a CRI below 80. They should not be used in residential areas.

I will say a few words about the lamps of each of the tested brands.

Osram.

One lamp tested. All parameters correspond to the stated ones. Nice light bulb.

Vitoone.

Two lamps tested. I tested a 4-watt candle of this brand in the spring and everything was bad with it - an unacceptable level of pulsation and a low CRI. Everything is much better with the new lamps. The pulsation of one lamp is 25% (this is quite acceptable), the second has practically no pulsation. CRI is more than 80, luminous flux is 97 and 88% of the declared value. For the price they are quite decent light bulbs.

Wolta.

Two lamps tested. Wolta has two series of lamps - regular in orange boxes and simple in white. All the orange ones I tested were good. Many whites have unacceptable levels of light pulsation. So, a 5.5-watt ball lamp has practically no ripple, while a GU5.3 spot has as much as 66%. This lamp cannot be used. As for the ball, the only complaint about it is 81% of the declared luminous flux. It shines like a 45-watt incandescent lamp, and the manufacturer claims the equivalent of 50 watts.

Space.

Four lamps tested. First of all, "Cosmos" misleads the consumer with its equivalent. On a 5-watt candle, the equivalent of 60 W is written in large letters, and in very small letters, 340 Lm, but this is not a 60 W equivalent, but only 40. In fact, this is not even the case - the lamp gives only 242 Lm and shines like a 30-watt incandescent lamp . The same is true with other lamps - a 7 W bulb has an actual power of 5 W, gives 422 lm instead of the promised 540, and shines like a 50-watt incandescent lamp, but not at all like a 75-watt one. A 5-watt spot consumes only 3.5 W, produces 226 lumens instead of the promised 370, and shines like a 40-watt halogen spot, not like a 50-watt one. The 3-watt R39 mirror lamp produces 199 lumens instead of the promised 240, but here the manufacturer made a mistake with the equivalent in the other direction. The fact is that mirror bulbs provide much less light than regular bulbs. A 30-watt R39 incandescent mirror bulb produces only 160 lumens, so 199 lumens is the equivalent of 35 watts. All lamps have good CRI values ​​of 82.3-83.1. The light pulsation of the first three lamps does not exceed 31%, but the R39 lamp has a pulsation of 47% and it is already visible, so I am forced to reject this lamp.

Camelion.

Two lamps tested. Both lamps have no light pulsation, but their CRI turned out to be very different. The candle has 82.5, but the ball has 74.4, so it is better not to use it in residential premises. Luminous flux is about 80% of the declared one.

Era.

Two lamps tested. Both lamps have no light pulsation, CRI 85.7 and 82.5. The luminous flux of the pear lamp is 86% of the declared one, the equivalent of 65 W (promised 70 W), but the luminous flux of the R63 DSLR is only 66% of the declared one, but this is most likely a manufacturer’s error with the luminous flux and the equivalent of DSLRs. The tested lamp shines like a 70-watt DSLR (the equivalent of 75 W is declared). Nice light bulbs. When purchasing, you just need to mentally subtract 5-10 W from the promised equivalent.

We are witnessing a revolution in lighting. LEDs are replacing other types of lamps in all areas. They have many advantages - with the same luminous flux they consume 6-10 times less electricity, emit much less heat and are more durable.

But not all lamps are equally useful. Chinese "watts", pulsations, narrow luminous flux are just some of the disadvantages that you may encounter when purchasing LED lamps. In order to really imagine what you can buy from us in Dzerzhinsk, we took 11 lamps and tested them. By the way, if you want to purchase them, it is indicated at the end of the material, Where can this be done and how to get it discount.

The lamps were tested in a laboratory using professional equipment.

So, first, a little educational program.

Power consumption (P)- the power consumed by the lamp from the electrical network.

Luminous flux (Lm)- the power of the luminous flux that the lamp emits. The higher it is, the brighter the lamp illuminates the space surrounding it. For 100W. incandescent lamps luminous flux is 1200-1350 lm. For an incandescent lamp with a power of 150 W, the luminous flux is 2000-2200 W.

Color rendering index (CRI) affects the perception of color. If the lamp has a low CRI, the color of objects may be distorted and the difference between similar shades becomes invisible. The closer it is to 100%, the better.

Ripple factor- a very important parameter that describes the pulsation of a light source. A lamp with a high pulsation rate can cause discomfort and headaches. SNiP 23-05-95 “Natural and artificial lighting” states that the pulsation coefficient of illumination of the working surface of the workplace should not exceed 10% - 20%. SanPiN 2.2.2/2.4.1340-03 “Hygienic requirements for personal electronic computers and organization of work” states that the lighting pulsation coefficient when working on a PC should not exceed 5%.

Let's get started!

The first lamp that came to us for testing is also the most powerful. This .

The manufacturer claims that a 20-watt lamp produces 1800 lumens of luminous flux, which, according to the manufacturer, corresponds to a 180-watt incandescent lamp. This is a significant exaggeration. An incandescent lamp with a power of 130-140 W will produce 1800 lumens.

As you can see, the passion for “Chinese watts”, which appeared in the 90s, does not let go of the Chinese to this day. But the lamp has a good color rendering index and low pulsations. Adjusted for the overestimated power ratings, the lamp is recommended for purchase. It can serve as an excellent replacement for a 100-watt incandescent lamp.

ASD-A60 15W, 3000K, E27. The second most powerful lamp in our test.

A real equivalent to an 80-watt lamp, it does not have the best color rendering coefficient and can serve as a replacement for an incandescent lamp in corridors and other non-residential premises.

Next patient - ASD LED-A60 11W, 4000K, E27 base.

The manufacturer promises 11 W of power and 990 Lm of luminous flux. What do we really have?

Well, the watts are too high as always, color rendering is already closer to satisfactory, and the ripple factor is excellent. The light bulb will be an excellent replacement for a 70-watt incandescent lamp for a bathroom or toilet, where color rendering is not so important.

Our next hero ASD LED-A60 7W, 4000K, E27 base.

7W of power and 630 lm of luminous flux are promised. Is it so? Let's get a look:

Traditional "Chinese" watts and as a result - insufficient luminosity, poor color rendering coefficient and traditionally low ripple. Such a lamp is only suitable for a closet or cellar. In another place, its light will clearly not be enough.

Next up are the lamps base E14, and our patient: meet LED-BALL 7.5W, 3000K.

As we see, everything is the same. The actual power is lower than declared, the color rendering index is mediocre and ripple performance is excellent. This lamp is well suited for additional illumination in rooms, but screwing it into table lamp we don't recommend it.

Next lamp - ASD LED-R50, 5W, 4000K, E14.

It's the same story in terms of power, but the equivalent power corresponds to the declared one. But! Ripple factor amounted to 30%, and this is simply unacceptable. Taking into account the fact that in other lamps from this manufacturer the pulsations were normal, let’s assume that we simply received a defective sample.

Now let's move on to the second manufacturer - Jazzway. This company also comes from China and now we will find out if this company has a penchant for "Chinese watts".

First test subject - Jazzway PLED-ECO-A60, 11W, 4000K, E27 base.

So, let's look:

The manufacturer has overestimated the power here, but the luminous flux does not differ so much, and the tested equivalent power corresponds to the declared one. The lamp also has a low pulsation coefficient. The only thing is that the color rendering index is a little less than truly good.

Next up - Jazzway PLED-ECO-A60 7W, 4000K, E27 base.

And ours first winner! Almost identical power and luminous flux, excellent color rendering index and low ripple. Strictly recommend this lamp in bedrooms and study rooms.

Now comes the turn of the most interesting lamp in our review - Jazzway PLED A60 OMNI 6W, 2700K, E27 base.

This is a lamp with filament emitters, and should completely replace traditional incandescent lamps. She looks the part. Well, let's see?

And this really the best lamp in our testing! Ideal lighting angles, power and luminous flux are even a little higher than stated, no pulsations and excellent color rendering index. Here she is, here she is the lamp of my dreams! We recommend apply it everywhere as a replacement for incandescent lamps for everyone who did not like the “classic” LED lamps.

And finally, let's see how things are going with Jazzway lamps in the E14 base.

Jazzway PLED-SP45, 7W, 5000K, E14

We have a slight overestimation of power, but the luminous flux practically corresponds to the declared one. The low color rendering index means that these bulbs are perfect for illuminating any room.

Jazzway PLED-SP R50, 5.5W, 5000K, E14

Everything is the same as with the previous lamp. The lamp is also great for illuminating rooms.

Even taking into account the love of manufacturers to inflate the parameters of lamps, our test shows that among them there are excellent examples that are worthy of taking a place in your chandeliers. And light bulbs Jazzway PLED A60 OMNI 6W, 2700K, E27 base,Jazzway PLED-ECO-A60 7W, 4000K, E27 base andASD LED-A60 20W 4000K, E27 base You definitely won’t be disappointed, because they combine all the advantages of LED lamps and are practically free of their typical disadvantages.

In the summer I launched a project to test LED lamps lamptest.ru. I planned to test 10-15 lamps per month, but it turned out completely differently. 557 lamps have already been tested (of which 17 are fluorescent, 59 are incandescent, and all others are LED). Such a large number of lamps were tested thanks to successful public fundraising (crowdfunding), which continues to this day.

Today I will tell you why I started this project, what will happen to it next, and I will ask you to answer questions, the answers to which will help determine how the project will develop.

When I first encountered household LED lamps, I realized that not all of them are good. I, like many, thought then that the light bulbs in Chinese online stores were the same as those sold in Russia, only cheaper. After several orders, I began to understand: something was wrong here. The Chinese light bulbs flickered unpleasantly, gave off a nasty greenish light and shone much dimmer than promised. Then, I did not yet know that the pulsation of light from LED lamps depends on the electronic driver board hidden in the lamp base; the quality of light is largely determined by the color rendering index (CRI), which for most lamps from Chinese online stores is very low, but with real power and brightness, Chinese sellers can lie two or three times.

I started looking for information about the real parameters of LED lamps, but there was very little of it on the Internet: in order to measure light parameters you need professional and very expensive equipment, which is only available in certified laboratories, and they do not have the right to share the results of their tests.

Fortunately, at the beginning of 2014, fate brought me together with a company that had a device for testing the parameters of Viso LightSpion lamps. They bought the device at a lighting exhibition in Singapore and, apparently, there is only one in Russia. We discussed with the owners of the device how great it would be to start testing all the lamps that are sold and publish these honest results. They offered to come to them once a month and test the light bulbs, which I started doing in February 2014. At first, all data was simply recorded in an Excel table. Then we started thinking that it would be great to make a website with convenient filters for viewing the results.

A wonderful programmer from Nizhny Novgorod, Sergei Andreev, responded to my cry for help and created a fast, beautiful and convenient website LampTest.ru, which was launched on June 24, 2015.

The device measured all parameters of the lamp except one - light pulsation. Fortunately, the developers of the domestic Lupine device provided our project with their device.

Most recently, Andrey Karasev joined the project team, who helps process the results and enter them into the database.

So, today 557 lamps have been tested. I wanted to make an anniversary post after the 500th light bulb, but it didn’t work out. :) I tested LED lamps from 56 brands, and at least 5 types of lamps from 30 brands were tested. These brands are: artpole, ASD, Camelion, Diall, Ecola, Gauss, IEK, IKEA, Jazzway, Kreonix, Lexman, Madix, Navigator, OSRAM, Philips, REV, Robiton, Smartbuy, Supra, Thomson, Uniel, Wolta, X- Flash, Space, Lisma, Nanolight, Online, Start, Economy, Era.

Unfortunately, it may happen that soon I will not be able to use the Viso LightSpion, so I am now trying to test as many lamps from as many brands as possible. I don’t want to guess what will happen when I lose access to the device, I hope there will be a way out.

I created project groups on Facebook https://www.facebook.com/lamptest.ru and VKontakte https://vk.com/lamptest. In groups, I will talk about all the news of the project - what I am testing, what changes are happening on the site, what interesting things were discovered, and many other interesting little things that go beyond the scope of large blog articles. Add yourself on the social network that is most convenient for you.

I tried to test mainly lamps with “warm” light 2700-3000K, since I think that such light is more suitable for the home. I think there is no point in testing low-power lamps. It seems to me that it makes sense to test ordinary pear lamps with an E27 base with an equivalent of at least 60 W, “candles” and “balls” with an equivalent of at least 40 W, and spotlights with an equivalent of at least 35 W.
