In the spring of 2018, new-generation LED lamps appeared in IKEA stores. These lamps have very high color rendering indices (over 92), they support brightness control, and the light turns yellow as the incandescent lamps dim, five of the eight new lamps have no ripples, they are completely silent when turned on at full brightness (when dimming some lamps have noise, but very weak), they use a new technology for the arrangement of LEDs, combining the advantages of filament and ordinary LED lamps.
I bought and tested new lamps.
IKEA LED lamps are rightly considered among the best on the market. IKEA has two lamp series: non-dimmable RYET and dimmable LEDARE.
RYET lamps correspond to the best lamps of other brands - they have a color rendition index above 80, they do not have a ripple, and the actual parameters exactly correspond to those stated.
Ledare lamps are the only LED lamps on the Russian market whose color rendering index exceeds 90 and they support brightness control (dimming). But these lamps were imperfect - many of them made a noise (buzzed), especially when dimming, and the ripple factor was 10-20%. Such a pulsation is not visible to the eyes, but the camera of the smartphone sees it well and many were confused by the presence of such a pulsation. In the new generation, these shortcomings are almost eliminated.
Now on sale appeared eight lamps of the new generation:
A transparent candle 400 lm 703.888.18 LED1721C6 for 399 rubles;
Matte pear 600 lm 703.887.57 LED1709G7 for 399 rubles;
Frosted pear 600 lm with E14 503.888.38 LED1705G7 base for 399 rubles;
Large transparent ball 600 lm 903.887.80 LED1710G7 for 399 rubles;
Large matte ball 1000 lm 103.632.98 LED1712G11 for 599 rubles;
Spot GU10 600 lm 403.632.30 LED1722R8 for 399 rubles;
Spot GX53 600 lm 703.651.00 LED1707X7 for 399 rubles;
Spot GX53 1000 lm 603.650.92 LED1706X11 for 499 rubles.
In the lamps of the new generation of the LED line, coated with phosphor, very similar to the filaments of the lamps of the same name, are placed on aluminum plates, and on each plate two rulers are placed side by side. Aluminum plates are connected to the radiator in the base of the lamp and the LEDs are cooled much better than in the filament lamps. Unlike filament lamps, the power is connected to the LED rulers not from two sides, but only from below.
If you look closely, you will notice that the color of the phosphor in the neighboring lines is slightly different, and this is no accident.
In one of the two lines, the light is warmer - 2000-2100K, the second one is colder. At a low brightness, only one (warmer) ruler in each group is lit and the lamp gives a more yellow light. With increasing brightness, the brightness of the first ruler first increases, then the second ruler turns on and their light mixes. The stronger the second line, the whiter the light. When both lines are burning at full power, the lamp reaches the declared color of 2700K.
For spots, the color change during dimming is done differently. At first, warmer LEDs light up, then their light mixes with colder light, then the warmer LEDs go out.
All lamps allow you to adjust the brightness of almost zero, and if the dimmer is capable of it, the minimum brightness level is a few tenths of a percent of the maximum.
IKEA produces the A60 pear lamps not only with the E27 base, but also with the E14 base. There are many chandeliers with small E14 “minion” cartridges, in the ceiling of which such large lamps are placed and this allows you to install bright lamps with good cooling in them that will last for a long time, unlike the tiny G45 bulbs in which with the same power (7-8 W) LEDs operate in extreme conditions.

Matte pears differ in design from other lamps. In the center they have a pole, outside of which the LEDs are located, and inside the driver.
A large matte ball is more traditional in design - a board with LEDs, followed by a driver.
As I wrote above, in full brightness mode, all the lamps are completely silent. When adjusting the brightness, a transparent ball remains silent, the spots are GU10 and GX53. Pears, a candle and a matte ball, when the brightness decreases, begin to hum quietly, but this sound is no longer heard twenty centimeters from the ear.
I measured the basic parameters of the lamps.
Luminous flux, color temperature and color rendition index were measured using a
two-meter integrating sphere and a Instrument Systems CAS 140 CT spectrometer , lighting angle and consumption characteristics with a Viso Light Spion instrument, power consumption with a
Robiton PM-2 instrument, pulsation with an
Uprtek MK350D instrument . The minimum operating voltage, at which the luminous flux decreased by no more than 10% of the nominal, was measured using a
Lamptest-1 device, Stable Stab Instab
500 , LATP Suntek TDGC2-0.5 and an
Aneng AN8001 multimeter . Before measurements to stabilize the parameters of the lamp heated for half an hour.
The luminous flux of the pear lamps is 2% less than the declared one (this is within the allowable range), all other lamps are brighter than stated, and the spots are made with a good margin - their luminous flux is 11-21% higher than the declared one.
The color temperature is very close to the stated 2700K (less than one percent difference).
The color rendition index of all lamps is above 90, and at a candle it reaches 93.8. Here is its spectrum.
Pulsations at a candle, pears, a large transparent ball and spot GU10 are practically absent. The large frosted ball has a ripple level of 6.6%, while the GX53 spots have 12 and 18%. Such a pulsation is not visible to the eyes, but it is still unpleasant that it exists. It is surprising that the ripple was found in GX53 lamps and a large ball, because in their housings there is much more space for the filter capacitor than in the housings of other lamps. I hope this will be fixed in new versions of the lamps.
On the packaging of the lamps, the operating voltage range is 220–240 volts, but virtually all the lamps operate at a voltage drop to 175 volts, and some at lower voltages.
Candle, pears and a large transparent ball give wide angles of illumination, in fact, not inferior to the filament lamps.
For example, let's compare the lighting angle of an IKEA candle and OSRAM filament candle.
Lighting angles of pears and a large transparent ball.
The angle of illumination of a large frosted ball.
Each LED at the spot is equipped with a lens, so they give a narrow beam of light: spot GU10 33 °, spots GX53 - 34-35 °. For GX53 spots, you can increase the illumination angle to 110 ° by turning the glass with the lenses.
For home use, this does not matter, but all lamps have a high power factor - 0.83-0.93 (for ordinary LED lamps, PF is usually around 0.5).
All IKEA lamps are guaranteed for two years, and during the year the lamps can be returned to the store even in opened packages without giving a reason.
Now, by simplifying the design, reducing the cost of the components used and reducing the reliability, the price of LED lamps on the market has fallen dramatically. More or less decent lamps cost about 100 rubles, and sometimes quite decent for the characteristics of the lamp, they sell even
for 49 rubles . Looking at such prices, buyers began to believe that lamps for 150 rubles are already too expensive, so new IKEA lamps seem to them prohibitively expensive. But it is important to understand that these are lamps of a completely different level and other lamps with such quality of light are simply not on the market (there are only LED strips with high CRI, which are even more expensive).
IKEA has made another step forward in LED lighting. Candle, pears, spot GU10 and a large transparent ball in their technical characteristics and capabilities today are ahead of all other brands of lamps on the Russian market. I hope in the near future there will be other lamps of the new generation - a frosted candle, pears 1000 lm, and the GX53 spots and the matte ball will be modified to completely eliminate the ripple.
PS I understand perfectly well that this review may look like an ad. I solemnly swear that I did not receive money or any other benefits from Ikea, and until the review was published, IKEA did not know that it would be written. They just took and made the best in the world of light bulbs.
