Test of LED lamps gu 5.3. Navigator LED lamps. Which model is the most profitable?

11 models passed the endurance test energy saving lamps: fluorescent and LED samples in the “budget” price category.

In the labeling of their products, manufacturers indicate how many hours the lamp will operate. For LED models this is an average of 30-40 thousand hours, for fluorescent models - 10 thousand hours. A resource test carried out in the laboratory of Roskontrol made it possible to determine whether the brightness of the lamps changes over time, as well as how frequent switching on and off affects their service life.

Two copies of each lamp model were installed in an automated test bench. Its power supply is stabilized in voltage and frequency, which allows for the most correct operating conditions for the light bulbs. At the stand, one light bulb of each type worked for 1000 hours continuously, and the second - in pulse mode, turning on for two minutes and then resting for the same amount of time.

During the testing process, a number of parameters were measured:

• heating during operation;
• brightness when turned on and startup time;
• noise during operation;
• Compatible with brightness control (dimmer).

A sample operating in pulsed mode helps evaluate the resistance of the light bulb design to frequent switching on. Essentially, this is an imitation of intensive use (for example, in a bathroom), only in accelerated mode.

Test results

Based on the testing results, it was possible to identify which light bulbs will save energy and not disappoint with poor performance. We go from worst to best.

gausselementary 23217A

Pros: No merits worth mentioning were identified.

Minuses: Not compatible with dimmer control. The measured power is noticeably lower than declared. Significant drop in brightness after just 1000 hours continuous operation.

Verdict: The gauss elementary 23217A model formally passed the resource test, but during continuous operation for only 1000 hours (4% of the declared resource), the loss of brightness of the unquenchable sample was 17%. In addition, the measured power turned out to be noticeably lower than declared.

ERASP-M-12-827-E27

pros: Turns on without delay.

Minuses: It turns on immediately, but at less than half the brightness. Over 1000 hours of continuous operation, the loss of brightness was 7%. The measured power is almost 22% less than declared. Low resistance to frequent switching on. Incompatible with brightness control (dimmer).

Verdict: Despite the fact that this model formally passed the endurance tests, it is at the lower limit of the requirements: resistance to frequent switching on is lower than that of competitors, and the loss of brightness during continuous operation of only 1000 hours was 7%. And there is a huge difference between the measured power and the declared one.

CamelionLH13-FS-T2-M/827/E27

Pros: Excellent resistance to frequent use. This means that the light bulb can be used, for example, in bathrooms. The light turns on, albeit with a delay, but at 2/3 brightness.

Minuses: Delayed switching on. Incompatible with brightness control (dimmer).

Verdict: This fluorescent light bulb can be safely used where the light is turned on and off frequently (for example, in bathrooms or in table lamps). The light turns on without delay, although not at full brightness. Based on the totality of indicators, it is a worthy model.

• Econur 1411130

pros: Turns on without delay.

Minuses: Not compatible with dimmer control. The measured power is lower than declared. It is not recommended for use in bathrooms of crowded rooms (in this mode it will last for a maximum of 1.5 years).

Verdict: The measured power turned out to be lower than declared, although the spread is not fatal. In addition, the model does not tolerate frequent switching on well, so it is better not to use it in bathrooms and table lamps. But when used in constant glow mode, it can last quite a long time.

• "Every day" FST2 1411130

pros: Decent (in comparison with analogues) tolerates frequent switching on; Turn on without delay;

Minuses: Not compatible with dimmer control. The measured power is slightly less than declared.

Verdict: Despite the fact that formally this model has passed the endurance tests, it is at the lower limit of the requirements: resistance to frequent switching on is lower than that of competitors, and the loss of brightness in just 1000 hours of continuous operation of the watch was 7%. And there is a huge difference between the measured power and the declared one.

• EcowattM-FSP 11W840E27

Pros: It tolerates frequent use well (in comparison with analogues).

Minuses: Turns on with a delay and at less than half the nominal brightness. A bad option if you need light immediately and in full. Incompatible with brightness control (dimmer). A characteristic feature of the majority fluorescent lamps points

Verdict: A typical fluorescent light bulb that can be used in rooms where the lights are turned on and off frequently (for example, in bathrooms). Among the shortcomings, we note the inclusion with a delay and with low brightness. Not the best option, if you need light right away, but otherwise it’s a good model.

• Jazzway PLED-SP

pros: The resource test passed without any complaints.

Minuses: Not compatible with dimmer control. The measured power is noticeably lower than declared. It starts in “turbo mode”, which can shorten the life of the LED unit.

Verdict: Both samples of the Jazzway PLED-SP model passed the resource test without any complaints. But experts were wary of “turbo start”, which could reduce the service life of the LED, as well as the fact that the declared power turned out to be 20% higher than measured.

• ERALEDsmdB35 7w-827-E27-Cler

Pros:

Minuses: Incompatible with brightness control (dimmer). The measured power is 26% lower than declared.

Verdict: During testing, a complaint about the ERA model LED smd B35 7w-827-E27-Cler only one occurred, but it was serious: the measured power was a quarter lower than declared! In addition, there is concern about the “turbo start” of the LED, which may affect its durability.

• CamelionLEDUltraLED7.5-G45

Pros: The resource test passed without any complaints.

Minuses: Incompatible with brightness control (dimmer). The measured power is a quarter lower than declared. It starts in “turbo mode”, which can shorten the life of the LED unit.

Verdict: For a high-quality LED lamp, 1000 hours of operation is nothing. It is gratifying that the Camelion LED Ultra LED7.5-G45 did not show any degradation during this period. However, the declared energy consumption turned out to be significantly higher than measured, and yet an LED light bulb is often chosen based on power.

• Volta 25Y45GL7E27

pros: Successfully passed the resource test. The indicated power consumption corresponds to the measured one.

Minuses: Not compatible with dimmer control.

Verdict: Among the LED models tested in the fall of 2016, this one turned out to be the most “honest”, showing the minimum discrepancy between the measured and declared power. The resource test was passed successfully by both samples

• Cosmos 7WLEDA60E2745

Pros: Successfully passed the resource test.

Minuses: Incompatible with brightness control (dimmer). The measured power is slightly lower than declared.

Verdict: The measured power of the Cosmos 7W LED A60 E2745 is 9% lower than declared, but otherwise the model did not cause serious complaints and successfully passed the resource test.

For a typical fluorescent lamp, 1000 hours of continuous operation is only 10% of the declared service life, and for an LED lamp it is generally 2-5%. Therefore, most lamps, after working for 1000 hours, not only did not work worse, but even vice versa. For example, the brightness of LED “Era” increased by 19%, and fluorescent lamps “Every Day” and Ecowatt - by 7%.

Only two samples dimmed during the life test: LED gauss elementary by 17% and fluorescent “ERA” by 7%. It is unknown whether this negative dynamic will develop with further operation, but it is an alarming symptom.

According to experts, for LED lamps, the 15,000 switching times included in the program are absolutely normal, since even frequent clicks of the switch do not particularly affect the life of lamps of this type.

High-quality luminescent models, based on the operating time declared by the manufacturer and the average frequency of use, should withstand from 10 to 15 thousand inclusions. Otherwise, the lamps will have to be changed too often, which will make their use unprofitable for the consumer.

As expected, in pulse mode everything LED bulbs survived 15,000 starts without problems. Among the luminescent models, the leaders are Ecowatt and “Every Day”: they have worked over 10,000 cycles. On the contrary, “ERA” did not show a very good result, failing after 7056 starts. This in itself is not a violation, since most often manufacturers of luminescent models do not declare the estimated number of inclusions at all.

“ERA” did the same. Therefore, we can talk about the results only in the format of comparing results that fit or not into the range of consumer expectations for the ability to use a light bulb even in a room or in a bathroom. After all, the manufacturer, as a rule, does not provide any recommendations for the use of its products!

True, the plastic of the luminescent sample of the ERA brand melted. This is an alarming symptom, since in the previous life test a similar light bulb of the same brand began to emit smoke.

• Heating during operation. Almost everything in the base area is scalding hot energy saving light bulbs– about 70 degrees. The “coldest” is gauss (48 degrees), the luminescent Camelion (93 degrees) is the hottest. In view of this, in lighting devices that a person may accidentally touch, experts recommend using led light bulbs, since they do not have an open glass bulb, but only a plastic casing. Therefore, the risk of destruction or burns is minimal.
• Turn-on brightness and startup time. LED models turn on instantly and at full brightness. Fluorescent light bulbs start up with a certain delay (it can be measured in tenths of a second, or can reach up to two seconds), and the maximum luminous flux does not begin to be produced immediately, after 30-60 seconds. Therefore, if you need bright light right away, then there is no alternative to LED models. Among the luminescent samples, Camelion and Ecowatt take the longest to start, and the latter initially produces approximately half of the nominal brightness. Like ERA, but at least it starts without obvious delay.

Which model is the most profitable?

With comparable brightness, the energy consumption of an LED lamp is about 70% of the energy consumption of a fluorescent lamp. At the same time, LED lamps, as the test results show and as the manufacturers themselves say, are more durable.

The most cost-effective per hour of use are LED bulbs from the ERA, Camelion and Jazzway brands. But outside the laboratory, the “lifetime” of a light bulb can be greatly reduced due to voltage surges, overheating (when working in tight lampshades) or simply factory defects in components.

Good LED lamps are still quite expensive, and due to changes in exchange rates they have become even more expensive.
Some of the lowest prices for LED lamps are now in IKEA stores.
I tested 11 current LEDARE LED lamps, costing from 169 to 599 rubles.

Ikea lamps from last year had problems with pulsating (flickering) light. The 7-watt candle lamps I tested had a pulsation rate of 63%, which of course is no good. All new lamps have a pulsation coefficient from 4 to 29%, which is quite acceptable for lighting residential premises (conventional incandescent lamps have a pulsation coefficient of 8-31%).

To measure the pulsation coefficient, a Lupin device was used, and a Viso LightSpion device was used to measure other parameters of the lamps. The equivalent power of incandescent lamps was determined based on the results of my measurements of the parameters of 22 incandescent lamps. All visual comparison photos were taken in manual exposure mode (ISO 125, 1/30, 1.8) with white balance set to 3500K.

All lamps correspond to the declared parameters, they all provide a luminous flux even slightly greater than what the manufacturer promises.

The table shows that all lamps have a high color rendering index (CRI), one of the lamps has a record value of 95.6. All but one of the lamps tested have a color temperature of about 2700K and produce light similar to incandescent lamps.

All lamps can be operated with switches that have an indicator.
Five lamp models support dimming (brightness adjustment).

Now let's take a closer look at the tested lamps. I'll start with the most powerful and most expensive lamp that can replace a 100-watt incandescent lamp.

1. Matte ball 1000 lm 002.574.82 E27 LED1309G15 13 W, dimmable. 599 rub.

www.ikea.com/ru/ru/catalog/products/00257482
lamptest.ru/review/ikea-00257482-e27-led1309g15

The lamp produces almost 1100 lumens, has a high CRI of 92.5, is only 5 mm longer than conventional lamps and has a standard diameter of 60 mm. The lamp is dimmable, but the minimum brightness when dimmed is only about half full brightness. Due to the matte shade, which has a diameter larger than the body, the lamp has a wide illumination angle of 233°.

A visual comparison with a 95 W incandescent lamp shows that the LED lamp shines slightly brighter, while its light is very similar to the light of an incandescent lamp.

2. Matte ball 600 lm 102.662.21 E27 LED1339G10 10 W, dimmable. 399 rub.

www.ikea.com/ru/ru/catalog/products/10266221
lamptest.ru/review/ikea-10266221-e27-led1339g10

This lamp is very similar to the previous one. It produces almost 640 lumens and has a high CRI of 94.2. The minimum brightness when dimming is also about 50% of full brightness; when using dimmers, the lamp buzzes a lot at any brightness (I tested it with an IKEA dimmer and a small Chinese dimmer on a wire). Illumination angle 232°.

A visual comparison with a 60 W incandescent lamp shows that the LED lamp shines with approximately the same brightness, but its light is slightly yellower than that of an incandescent lamp.

3. Matte ball 600 lm 4000K 702.871.07 E27 LED1402G8K4 8 W, dimmable. 399 rub.

www.ikea.com/ru/ru/catalog/products/70287107
lamptest.ru/review/ikea-70287107-e27-led1402g8k4

This is the only lamp in the test that has a neutral White light with a color temperature of 4000K. This light is better suited for an office or utility room. Externally, the lamp is exactly the same as the previous one. It produces a luminous flux of 687 lumens, its CRI is 83.7, and the illumination angle is 234°. Like the previous lamp, it hums when dimmed, although not so loud. The minimum dimming level is also about half brightness.

Visually comparing a lamp with this color temperature with an incandescent lamp is incorrect. All that can be seen is that its light is much colder and due to this it seems brighter.

4. Transparent ball 600 lm 003.014.23 E27 LED1423G9 8.6 W, dimmable. 399 rub.

www.ikea.com/ru/ru/catalog/products/00301423
lamptest.ru/review/ikea-00301423-e27-led1423g9

Unlike the other ten, this lamp was made not in China, but in Germany and is significantly different from the previous ones. It has a transparent shade and an original light diffusion system. The lamp produces a luminous flux of 592 lumens, which almost corresponds to the declared 600 lm, it has a high CRI of 92.1, and an illumination angle of 196°. The minimum dimming level is about 10% brightness; when dimming, the lamp hums quietly.

The light from the lamp is very similar to that of a 60W incandescent lamp in both brightness and color.

5. Matte ball 400 lm 102.666.93 E27 LED1221G7 6.3 W, 169 rub.

www.ikea.com/ru/ru/catalog/products/10266693
lamptest.ru/review/ikea-10266693-e27-led1221g7

The lamp is equivalent to a 40-watt incandescent lamp. Luminous flux 410 lm, CRI=91.5, illumination angle 255°.

6. Matte ball 400 lm 802.489.93 E14 LED1221G7 6.3 W, 169 rub.

www.ikea.com/se/sv/catalog/products/80248993
lamptest.ru/review/ikea-80248993-e14-led1221g7

This lamp differs visually and in parameters from the previous one only in the base - E14, not E27. I was sure that their “filling” was the same, but there were differences. The main parameters are almost the same: 413 lm, CRI=93.1, illumination angle 257°, ​​but the color temperature is much “warmer” - 2664K.

A visual comparison shows that the light from an LED lamp is much yellower than that of an incandescent lamp.

7. Small matte ball 200 lm 402.880.66 E27 LED1325G3 3.5 W, 199 rub.

www.ikea.com/ru/ru/catalog/products/40288066
lamptest.ru/review/ikea-40288066-e27-led1325g3

This small bulb produces very little light - less than a 25 W incandescent lamp - only 231 lm, CRI=94.6, illumination angle 212°.

When visually compared to a 25W incandescent lamp, the LED lamp is slightly dimmer.

There is an analogue of this lamp for the E14 base: 902.552.90 E14 LED1012G5 3.5 W, 199 RUR.
www.ikea.com/ru/ru/catalog/products/90255290
lamptest.ru/review/ikea-90255290-e14-led1012g5

While I have not tested this lamp, I can only show a visual comparison with a 25 W incandescent lamp.

8. Matte candle 400 lm 602.880.70 E14 LED1328C6 6.3 W, 249 rub.

www.ikea.com/ru/ru/catalog/products/60288070
lamptest.ru/review/ikea-60288070-e14-led1328c6

This lamp is a replacement for 40-watt candle lamps. It produces 416 lumens, has a high CRI=92.2 and a wide illumination angle of 248°.

Visually, the lamp is slightly brighter than a 40-watt incandescent lamp, and its light is slightly yellower.

9. Transparent candle 200 lm 102.880.01 E14 LED1327C3 3.5 W, 199 rub.

www.ikea.com/ru/ru/catalog/products/10288001
lamptest.ru/review/ikea-10288001-e14-led1327c3

This light bulb has a record CRI of 95.6, almost like an incandescent lamp. It contains one powerful LED producing 228 lm. Illumination angle 231°.

Although the manufacturer promises that this lamp is equivalent to only a 20-watt incandescent lamp, visually it shines brighter than a 25-watt incandescent lamp.

10. Spot 200 lm 802.879.89 E14 LED1318R4 3.6 W, 249 rub.

www.ikea.com/ru/ru/catalog/products/80287989
lamptest.ru/review/ikea-80287989-e14-led1318r4

Spot lamp on one powerful LED gives a narrow beam of light - 33°. Luminous flux 210 lm, CRI=83.

Visually comparing a spot with a regular incandescent lamp is of course incorrect. I will still give a picture, but I will not draw any conclusions.

11. Spot 400 lm 402.880.52 GU10 LED1334R7 6.3 W dimmable, 249 rub.

www.ikea.com/ru/ru/catalog/products/40288052
lamptest.ru/review/ikea-40288052-gu10-led1334r7

Spot for suspended ceiling with GU10 base. It also produces a narrow 38° beam of light. Luminous flux 444 lm, CRI=82.3.

Visual comparison with a 40 W incandescent lamp.

LED lamps that can be bought in Ikea stores are quite good, and in terms of price/quality ratio they are one of the best. They have a pulsation of light, but it is within normal limits. Not everything is good with dimming for those lamps that support it. Three out of four dimmable lamps tested did not allow the brightness to be reduced below half, and only one dimmable lamp did not buzz when dimming.

See all the test results of these and other lamps I have tested on the website lamptest.ru

© 2015, Alexey Nadezhin

In order to answer these questions and choose the ideal LED lamps in terms of price-quality ratio, I am starting a series of articles comparing LED lamps tested in the lamptest.ru project. To date, more than one and a half thousand lamp models have been tested, including lamps from all well-known brands that can be bought in Russia.

We will compare the results of testing sixty LED lamps designed to replace a conventional 60 W incandescent light bulb, tell you about the most important parameters of the lamps that you need to pay attention to, and give recommendations on which lamps are best to buy.

First, let's determine how much light such a light bulb gives. The parameter that determines the amount of light is called “luminous flux” and is measured in lumens (lm). The packaging of 60-watt light bulbs usually indicates a luminous flux of 710 lm. In Wikipedia and European standards you can find a value of 806 lm. In reality, incandescent lamps sold in stores provide less light and their brightness directly depends on the voltage in the network, which is often lower than the standard value of 230 volts.

We tested five 60-watt incandescent bulbs at 230 and 220 volts using the Viso Light Spion. The voltage was set with an accuracy of 0.1% using a Shtil stabilizer, a Suntek TDGC2-0.5 LATR and two Aneng AN8001 precision multimeters, calibrated using the high-precision Keithly 2000 Multimeter and GW Instek GPM-8212 instruments.

According to the measurement results, at a voltage of 230 volts the lamps produce an average of 650 lm, and at a voltage of 220 V - 540 lm.

By the way, previous measurements have shown that different types of incandescent lamps can differ greatly from each other, so based on this table you should not conclude that lamps from one brand are brighter than lamps from another.

Doctors and scientists recommend using lamps with “warm” light of 2700-3000 K at home, and the author agrees with their opinion. 40 models from twenty-seven brands took part in the comparison of “warm” lamps. The lamps in the table are sorted by measured luminous flux.

Of the models tested, 14 lamps that stated on the packaging that they replaced a 60-watt incandescent lamp or produced at least 540 lumens actually provided less light output. And Supra, Saffit and REV 7W lamps provide 1.5-1.8 times less light than promised and can only replace a 40-watt incandescent lamp. However, overestimation of the equivalent and luminous flux by the manufacturer is observed in many brands. This is clearly visible in the table.

Four lamps have unacceptably high pulsation.

The color rendering index of many cheap lamps is about 73. Such lamps can be used in auxiliary rooms (corridors, halls), but in living rooms, kitchens and bathrooms it is better to use lamps with CRI>80.

Not all lamps work correctly when using a switch with an indicator. For lamps that can be used with such switches, in the “off” column. the table contains the value "ok". The value "blink" means that the lamp flashes, and "hot" means that the lamp glows faintly when the switch is off.

LED lamps can use two types of drivers ( electronic boards that provide power to the LEDs) - linear and pulsed. When using a linear driver, the brightness of the lamp depends on the mains voltage, and as the voltage decreases, the brightness decreases. Typically, when using a linear driver, the brightness drops by 10% at 205-215 volts. The switching driver stabilizes the supply voltage of the LEDs, and the brightness of the lamp does not change over a wide range of supply voltages. As a rule, lamps with a pulse driver can operate without changing brightness when the mains voltage drops to 160 volts. The driver type is indicated in the "type" column.

Of the tested lamps, we can confidently recommend eight for purchase.

1. IKEA Ledare 303.059.76 LED1466G9. This lamp is the most expensive of those that took part in the comparison, but it is worth it, primarily because of the high color rendering index of 92.5 (note that of all the LED lamps sold in Russia, only Ikea Ledare lamps have a color rendering index higher than 90). In addition, this lamp, the only one of all those that took part in the comparison, supports brightness adjustment (dimming). The lamp parameters exactly correspond to the declared ones. Light pulsation of 10% is completely unnoticeable.
2. "Nanosvet L160 LE-GLS-8/E27/827". An excellent light bulb with honest characteristics at a good price. There is no pulsation, the backlit switch works. The only drawback is only a one-year warranty.
3. X-Flash 44788 XF-E27-A60-P-8W-3000K-220V. Great light bulb with a five year warranty and a good price. The only complaint against the manufacturer is that the equivalent is indicated incorrectly: 650 lumens is not 75 W.
4. Geniled 01210 E27 A60 7W 2700K. Great light bulb at a good price. Complaints to the manufacturer - the equivalent and color temperature are indicated incorrectly.
5. Osram LED STAR CLASSIC A 60 6.8W/827 FR E27. Nice lamp. The only drawback is that it does not work with a switch that has an indicator.
6. artpole 004296. The manufacturer of this lamp greatly inflated the parameters on the packaging (equivalent to 100 W and 850 lm, but in reality - 60 W and 649 lm), but the lamp is good, and if you know about this “feature”, you can buy it. Doesn't work with a switch that has an indicator.
7. Polaroid 30411908 PL60-6273. With this lamp it’s the other way around: for some reason the manufacturer underestimated its characteristics! The packaging indicated 6 W and 550 lm, but in fact it turned out to be 7.9 W and 640 lm. Doesn't work with a switch that has an indicator.
8. IKEA RYET 503.220.22 LED1512G8. A good lamp, honest parameters, but a little expensive. Doesn't work with a switch that has an indicator.

Of course, these are not all good lamps

The first three lines of the table are lamps Diall (own brand of Castorama stores), Auchan (own brand of Auchan stores), Lexman (own brand of Leroy Merlin stores), with which they played a cruel joke European standards, assuming a luminous flux of 806 lm as the equivalent of a 60-watt lamp. These lamps can be recommended for purchase, but as a replacement for 75-watt incandescent lamps, and not 60-watt ones.

The Wolta Simple 25Y60BL8E27-S lamp showed good results, but it was tested two years ago, and the author cannot recommend it, since now lamps under the same article number most likely have a color rendering index below 75.

The Feron LB-92 25457 lamp also showed good results, but almost the same Feron LB-91 lamp with higher power had a color rendering index below 75, which means that the manufacturer does not pay much attention to what LEDs are installed in the lamps and in the other things may turn out differently for the party.

The two Volpe lamps have high specifications on the packaging, but produce good light. We hesitate to recommend them, since other lamps of this brand have low color rendering indices.

The Philips lamp 871829175275200 has a cap of the same diameter as the body. Because of this, the lamp does not shine back at all, and when placed in a chandelier with the base up, the ceiling will remain dark. This lamp has a 22% ripple which is almost unnoticeable.

The “Era Economy LED smd A60-8w-827-E27 ECO” lamp also has a slightly noticeable pulsation of 22%.

The comparison included two Era Economy lamps with exactly the same name “smd A60-10W-827-E27 ECO”. One in a white box, the other in a red one. The one in the white box had a high CRI, but an unacceptably high ripple, and the one in the red box had no pulsation, but the CRI was low.

I would like to point out one more unpleasant thing. The brands Gauss, Smartbuy, and Era overstate on the packaging not only the luminous flux, equivalent and power, but also the color rendering index, indicating a value of 80, although in fact it is lower than 73.

It's the same story with Lexman 8 and 10 W and Auchan lamps - they are too bright to replace 60-watt lamps and are suitable for replacing 75-watt lamps. Unacceptable pulsation was detected in Ecola LED D7LV82ELC and Era Economy LED smd A60-8w-840-E27 lamps. OSRAM and Philips lamps have a color temperature of 6500 K - this is too cold light and not at all suitable for residential areas.

If you are looking for lamps with neutral white light, the following four lamp models are recommended for purchase from those included in the comparison.

1. "Nanosvet L161 LE-GLS-8/E27/840". An excellent lamp - a twin of the warm L160. The only drawback is only a one-year warranty.
2. "Era LED smd A60-8w-842-E27". The lamp produces 100 lumens less light than Nanosvet, but it successfully replaces a 60-watt incandescent lamp. A good lamp, its only drawback is incorrect information about luminous flux, power and equivalent on the packaging.
3. Lexman 7-A60 E27/40 R. The lamp is specified as a 45 W equivalent, but it produces 557 lumens and can fully replace a 60-watt incandescent lamp. The warranty for this lamp is 5 years.
4. Robiton 676-399 LED A60-8W-4200K-E27. Nice lamp. The only drawback is that it cannot work correctly with a switch that has an indicator.

Unfortunately, only “cheaper” Gauss and Camelion lamps were included in the comparison and models from other well-known brands were not included. This is partly due to the fact that many manufacturers have focused on making higher-wattage lamps and are no longer offering pear-shaped lamps that replace incandescent lamps under 75 W. In the following reviews we will definitely talk about lamps from these brands.

Reviews of single lamps are good for everyone, except for the ability to understand which of the lamps in neighboring reviews shines brighter and whether it gives the desired color temperature. Below the cut is a comparison of three different LED lamps in an equal battle.

So, the participants of today's comparison test:

1. Reference sample: Osram Duluxstar Mini Twist fluorescent lamp 24 watt warm spectrum. The actual measured power consumption is 20 watts. The lamp is 2 years old. The photo is on the far right. The price is about 150 rubles.

2. Lamp from the title of the review with. LED warm spectrum type “corn”. Claimed power consumption is 7 watts, actual power consumption is 5.9 watts. Price 6.1$. In the photo, second from the left. By the way, surprisingly durable construction. It came by mail (regular, not EMS) alone, in a small envelope, barely wrapped in one layer of half-shredded bubble wrap. When the postal workers unceremoniously threw the envelope onto the table, a distinct plastic knock was heard. Therefore, when I took the lamp, I was 80% sure that it was already dead. But surprisingly this turned out not to be the case.

3. Lamp with . Cold spectrum LED lamp of the “corn” type. Stated 4 watts, measured 4.6 watts. Price 13.7$. In the photo, second from the right.

4. Lamp with . Half corn LED lamp with 180 degree beam direction. The spectrum is cold. Stated 6 watts, measured 6.5. Price 12.7$. In the photo is the one on the far left. The only lamp from the review on SMD diodes. The plastic lamp base is divided into 2 parts. The part that is adjacent to the metal base is rigidly connected to the metal base. The part that is adjacent to the lamp is rigidly connected to the lamp. And they rotate relative to each other. Those. The twisted lamp can be directed in any way you like. However, a problem may arise in unscrewing the lamp if it is screwed into a lamp where there is no direct access to the static part of the base.

The testing methodology is quite simple. To determine the correct color temperature, we set the white balance to the “sunny” position, the deviation from which into yellowness and blueness is precisely perceived by the human eye. To determine the comparative brightness in a joint photo, we measure the exposure using the brightest lamp with additional manual exposure compensation of -1/3. Many even comparative reviews turn out to be useless due to the fact that their authors set the exposure haphazardly, as a result of which the lamps photographed are often overexposed. And the excess of luminous flux over dynamic range The camera matrix by 5% and 5 times gives the same white color in the picture, which does not allow correct comparison of different lamps, except perhaps by indirect evidence of the size of the surrounding light spots.

First comparison photo.
2 LED lamps (No. 2 at 9 o'clock and No. 3 at 1 o'clock) with a reference fluorescent lamp (at 5 o'clock). The photo clearly shows that the fluorescent lamp shines at least 2 times more powerful than diode lamps. Cold diode lamp No. 3 shines noticeably brighter than warm diode lamp No. 2. These differences are much more visible to the eye than in the photo. A cold diode lamp is slightly blinding, but a warm one can be viewed without discomfort. Its spectrum is quite pleasant and very similar to the spectrum of a warm fluorescent lamp.

Second comparison photo.
All 3 LED lamps. The arrangement is similar to the 1st photo, only instead of a fluorescent lamp there is lamp No. 4. The 4th lamp has more efficient SMD diodes and produces a more directional light output. Looking directly at her at close range is already very unpleasant. A clear champion in brightness, although this is achieved incl. due to directionality.

Another one useful thing, which can be measured with a camera - the flickering of lamps, which gives a stroboscopic effect that is unpleasant for the eye. Lamps No. 2 and No. 3 have some pulsation noticeable in the test image. But even in the picture it is clear that the pulsation is not clearly expressed. The stroboscopic effect is not noticeable to the eye. Lamp No. 4 gives a perfectly straight line without a pulse (some jagged edges are visible in the published photo, but these are compression artifacts; they are not present in the original photo).

№2

№3

№4

The fluorescent lamp is still the leader in brightness per unit of lamp cost. If the number of lamps in a chandelier is limited to a small amount (for example, three, as in mine) and you need bright light without too expensive lamps, a fluorescent lamp is the only right choice today (similar in brightness LED lamps cost 30 bucks a piece).

Warm LED lamp No. 2 produces a spectrum that is pleasant to the eye, similar to the spectrum of a high-quality fluorescent lamp. The cheapest lamp in the review, 2 times cheaper than LED competitors. However, it has the weakest light output (although for the same price you can install 2 times more lamps, which will clearly be more efficient). Also the most energy inefficient among LEDs. Apparently just because of the warm spectrum. An excellent option for a living space if the chandelier allows you to install quite a lot of such lamps.

Cold omnidirectional lamp No. 3 consumes the least electricity, while being the most expensive (probably mainly due to the greed of Dilextream). the total luminous flux is comparable to the brightest diode lamp No. 4, but distributed in all directions. Enough universal solution for lighting non-residential premises and indoor street lamps. Not suitable for residential premises due to the unpleasant cold spectrum (although this is not for everyone).

Cold directional lamp No. 4 is the brightest of all diode lamps compared. The most technologically advanced SMD diodes. Suitable for lamps adjacent to the wall or ceiling in non-residential premises. Unpleasant color for residential use.

“Unlike conventional incandescent lamps, which differ only in power and workmanship, LED lamps have many parameters that affect the quality and safety of lighting.”

"Light flow

The brightness of a lamp, or rather the amount of light that a lamp gives, is determined by the “luminous flux” parameter, measured in lumens (lm).

For ordinary lamps (pears, candles), you can approximately estimate the required luminous flux by multiplying the power of a conventional incandescent lamp by 10: 40 W - 400 lm, 60 W - 600 lm, 100 W - 1000 lm. So, if you're looking to buy an LED bulb to replace a 60-watt incandescent bulb, look for bulbs with a lumen output of at least 600 lumens.

Unfortunately, many manufacturers overestimate the luminous flux value. In reality, it may turn out to be even half as low as stated, and a lamp that should shine like a 60-watt incandescent lamp will only shine like a 25-watt one."

"Colorful temperature

Incandescent lamps emit a warm yellowish light with a color temperature of 2700-2800K. If you want an LED lamp to produce light as similar as possible to incandescent lamp light, choose lamps with a color temperature of 2700-2800K. Many LED lamps have a color temperature of 3000K - this is whiter, but no less comfortable light. Light from lamps with a color temperature of 4000K is called “neutral white”. This light is more suitable for office spaces. It is believed that white light helps improve performance, and yellow light helps to relax and unwind, so at home in the evening the light should be warm with a color temperature no higher than 3000K. Lamps with cool white light 5000K and above are intended for use in utility rooms. There is no place for them at home."

"Color rendering index (CRI, Ra)

At low Ra, shades are less visible. Such light is visually unpleasant, and it is very difficult to understand what is wrong with it. For incandescent and solar lamps, Ra is higher than 98, for good LED lamps it is more than 80, for very good lamps it is more than 90. It is better not to use lamps with Ra below 80 in residential areas.”

"IKEA LED lamps are deservedly considered by many to be the best that can be bought in Russia. First of all, many IKEA Ledare lamps have a very high (91.1-96.1) color rendering index (CRI) and it should be noted that in fact these are the only lamps with a CRI>90 , available in our country. Many IKEA lamps are cheaper than competitors with better parameters."

"Light pulsation

Light pulsation leads to eye fatigue and a general deterioration in well-being, so it is very important to use only those lamps that do not have visible pulsation. According to SNIP for various types premises, the light pulsation is normalized in the range of 5-20%"

“According to the latest data, for the complete absence of harmful effects on humans, pulsations should not be more than 4-5%

Pulsations with a depth of 20% cause the same level of disruption of normal brain activity as pulsations with a depth of 100%. The person feels inexplicable discomfort, fatigue, and dizziness. High-frequency light pulsations affect human hormonal levels, daily biorhythms and associated performance, fatigue, and emotional well-being.

Systematic exposure can serve as an indirect cause of permanent depression, insomnia, cardiovascular diseases and cancer. An unfavorable effect of light fluctuations on the photoreceptor elements of the retina has also been revealed."

"Guarantee

All LED lamps have a warranty of 1 to 5 years. Stores are required to replace lamps under warranty during this period if they fail. In addition, according to the consumer protection law, you can return the lamps to the store within 14 days after purchase if you do not like them, provided that you have intact packaging and, if possible, a receipt."

"If the lamp you are interested in is not yet on the website lamptest.ru, I recommend following the following criteria choice:

If the package says "no ripple" with high probability The pulsation of the lamp light will be less than 5%. If this is not indicated and it is possible to turn on the lamp, look at its light through the camera mobile phone. There should be no stripes across the screen. Try twirling a pencil or other long object in front of the lamp. If the contours of a pencil are blurred, there is no pulsation; if you see “several pencils,” there is a visible pulsation and such a lamp is not worth buying.

See what the skin of your hand looks like under the light of a lamp. If the color is grayish, the lamp has a low color rendering index and it is better not to buy it.

Pay attention to the production date of the lamp (for most lamps it is indicated on the body). If a lamp was produced more than two years ago, it is better not to buy it - progress is very fast and modern lamps are better than those that were produced before.

After purchasing, take a photo of the receipt. If the lamp fails, this photo will help you replace it under warranty if the regular receipt gets lost or fades."

Advantages of LED lamps:

1. High luminous efficiency.

2. High mechanical strength, vibration resistance.

3. Long service life.
Lamp life is highly dependent on temperature. When operating at temperatures above room temperature, the service life is reduced.

4. Low inertia - they turn on immediately at full brightness, while mercury-phosphorus (fluorescent-economical) lamps have a turn-on time from 1 s to 1 min, and the brightness increases from 30% to 100% in 3-10 minutes, in depending on the ambient temperature.

5. The number of on-off cycles does not have a significant impact on the service life of LEDs (unlike traditional light sources - incandescent lamps, gas-discharge lamps).

6. Safety - no high voltage required, low temperature of LED or fixture, usually not higher than 60 °C.

7. Insensitive to low and very low temperatures. However, high temperatures are contraindicated for LEDs, as for any semiconductors.

8. Environmentally friendly - no mercury or phosphorus inside the lamp.

“The technology is constantly being improved in order to make lamps more environmentally friendly, bringing only benefits to our eyes. However, as with other devices, there are cheap and expensive options. Manufacturers sometimes do not indicate all the characteristics on the box. Let’s briefly consider what problems may concern people when using LED lamps.

1. This is, first of all, emission spectrum. In 2013, information about the dangers of LED lighting spread across the Internet, citing a study by Spanish scientists from the Complutense University, which showed that the light emitted by LED lamps can significantly damage the retina of the human eye. Sometimes there are notes that supposedly the spectrum of LED lamps contains a hard blue and even ultraviolet component, which is harmful to our eyes. Indeed, there are sanitary standards for UV irradiation of the retina, which are recommended not to be exceeded. Note that the strongest source of UV radiation is the Sun. All experiments to confirm the harmfulness of UV radiation were carried out on animals and the harmful effects on the retina were noted only with prolonged exposure to very bright light.

Nowadays, most household lighting lamps have a color temperature of 2700-3000 K, which is far from the UV region. And yet, when choosing a lamp in a store, pay attention to its color temperature. This parameter is always on the box.

As for the conclusions made by Spanish scientists, they relate to the radiation of all kinds of LED screens, such as the displays of all kinds of gadgets, computers, televisions, etc. Scientists have proven that if you look at such screens for a long time, without any eye protection, this can actually lead to gradual changes in the retina. Therefore, it is recommended to protect your eyes when long work with a computer and special glasses. Take frequent breaks. We don’t look closely at lighting fixtures for a long time, so there is no harm from them.

2. Flicker of light. Light pulsations are very characteristic of old fluorescent lamps. For good LEDs they are minimal - less than 1%. Although there are cheaper lamps with ripples of more than 60%. This parameter is usually not indicated in the description on the box with the lamp. We can advise you to simply buy not the cheapest modern lamps. In them, power is supplied through special drivers, and not through capacitors. There are tips on the Internet on how to independently evaluate light pulsations. It is suggested to look at the lamp through a mobile phone camera.

3. Another problem related to the spectrum of the LED lamp that is sometimes mentioned on the Internet is harm of bright white color on human health. This does not mean the effect on vision, but the effect on the nervous system, suppressing the production of the sleep hormone - melatonin. It is recommended in the evening, a couple of hours before bedtime, to reduce the brightness of the lamps and use warmer light. Unlike fluorescent lamps, some LED lamps, like incandescent lamps, support the function of dimming using power controls “dimmers”, this should be indicated by the manufacturer on the packaging.

4. Insect problem. They love bright light, and they are less attracted to incandescent lamps than diode lamps, including because of their strong heating. Diode lamps, which are brighter than incandescent lamps and do not heat up, sometimes gather clouds of flying insects around them. This problem is especially relevant when lighting large southern cities, where sometimes there is an “invasion” of various mosquitoes, flies, and cicadas.

The LED lamp is one of the most necessary and important inventions of our time. It not only improves the quality of light in our homes, but also helps solve the problem of energy conservation - one of the most pressing problems on Earth."
