Test of Russian LED bulbs SvetaLED

Recently, in my hands, quite by chance, got light SvataLED, the company "Svetlana-Optoelectronics"Which should be on the market in the early fall. This is analogous to incandescent power of 40 watts. Characteristics bulbs are impressive — 10 years warranty, 100,000 hours of work, only 6 watts of power consumption. Digging also will release a 60-watt equivalent and paws, but this so far failed to produce, however, some conclusions can be drawn on this lamp.

As a sample for comparison, I have gained market Savelovsky its Chinese competitor — a light bulb Ecola — 4.2W (35W equivalent incandescent bulbs, no more). At the same time, in absentia, this lamp is comparable with other Russian products — Lamp "Optolyuks-E27", presentation of which took place a little earlier.

Unfortunately, the lamp can not be directly compared, because the lamps of different classes, but some of what conclusions can all still possible.

Outside

So, I present you the first Russian bulb out of the category of unique 40Vattnym incandescent bulbs.

Lamp design is quite pretty. Assembled with high quality. The site says that the lamp dimming support, that is a smooth change of brightness. Chinese lamp is not dimmable.

Light even though coolish. But box and indicated. There is a version with a warmer light.

Now look at the Chinese.

The case is assembled tightly, but comes through the glue is worn.

Light uneven, closer to the base shines dimly. Moreover, it can be seen in the photo is not so good, although a dark band closer to the cap in sight. In reality, it is even thicker. In "SvetaLED" light is steady in all areas bowl. Because of this, the Chinese lamp shines mostly forward, the angle of illumination is lower than that of the Russian lamp. This is well illustrated by the shadows on the lampshade lamp. China is only suitable for table lamps.

Light a warm (2800K), but there is also a version with a cool color. And two graduations, or warm or cold. In "SvetaLED" three grades, here represented by the middle option "neutral white" (3500-4500K). There are still "cool white" (4500-6500K) and "warm white" (2000-3500K).

Inside

Let's see what's inside. Actually, I'm not going to break the light bulb "SvetaLED", it gave me just test the software. However, the case has ordered otherwise. In "SvetaLED" no edges, and it's great rides. Then one time, she took it and rolled off the table and shattered into small pieces. This gives us an opportunity to look inside, though, and raises questions about the extent of damage to health momemu that will be caused to me when the owner finds out light bulbs that I had broken.

So insides "SvetaLED" already 8 LEDs.

Diffuser — Frosted glass.

Eight LEDs — a lot. The other Chinese lamp that's just showed me was six, while the Chinese lamp complete analog of the lamp. However, there is such a figure as "luminosity", measured in lumens, and probably for this indicator loses the Chinese product.

Since it happened, and the interior lights of the Russian managed to see, I decided to break up as well and Chinese lamp. It was not there. If the bubble «SvetaLED» is made of frosted glass, making the light more evenly, then the Chinese products normally be plastic. Glass transmits more light, 98%, but beats. Plastic holds more light, but does not break.

On the one hand, this makes the lamp practically unbreakable, well, on the other hand, I have serious questions to what is technologically decision, I Svetlanovskaya lamp light is a more even, apparently including through the use of glass. Well, take a look inside.

Frankly, I was too lazy to count how many LEDs, a lot of them. It is obvious that this is a less technologically advanced and modern than applied in the bulb "SvetaLED".

In total

For all the characteristics of our light bulb better Chinese. She wins in everything except the claimed power, but do not forget that the Chinese equivalent lamp 35-watt bulb (and I think most 30-watt) and "SvetaLED" — 40W.

In the rest, including the period of guarantee for durability and — The Russian unit better. For the price of hard to say how much it will cost "SvetaLED" on store shelves, but the manufacturer promises 450 rubles per 8W, ie 6W will cost about 350-400 rubles. A Chinese man is 413 rubles.

In fairness, it must be said that not all Chinese lamps such awful. A little earlier I was able to hold in their hands the other Chinese model. Two light bulbs ordered directly in China. Delivery lasted two and a half months. The model differs from I have purchased in Russia, and much more like a "SvetaLED", except that the design is slightly different, with "SvetaLED" ribs inside, outside the Chinese. And this just 6 LED lights inside, as opposed to "SvetaLED", who, as we saw 8 LEDs.

Comparison with the "Optolyuks-E27"

Having dealt with the Chinese, let's talk about another Russian bulb — OptoGaN. When our portal told about the presentation of this bulb, some who in the comments noted that its design is very similar to the design of Chinese lamps. In fact, like light "Optogan" the Chinese only in that it has the radiator fins. Themselves rib lamp dimensions, shape, not like at all. Edges thinner than 10 times, more of them, they have small holes for better air circulation. But if pro "Optolyuks" we can say that it is similar to the Chinese only cooling fins, something about "SvetaLED" we can say that it is not simil
ar to the Chinese only in the absence of these edges (well, much better build quality). Otherwise, the size, shape, they are almost identical.

And the thing is this. In the Chinese lamps using multiple LEDs. I was convinced, from six to infinity. LEDs are the most powerful, so do not require a large and complex radiator teplootvedeniya. The same time-tested solution and applied in the light bulb, "Svetlana". From this point of view — no innovation, just a higher build quality than the Chinese. But technically, the lamp does not outstanding. But inexpensive and compact.

And here at Optolyuksa uses only one LED chip!

In this case, it shines brighter than a few pieces of the ordinary. In China 40W light bulb was 6 LEDs have "SvetaLED" eight. And Optoganovskogo Optolyuksa only one chip with high integration produces light as a 60-watt incandescent bulb. Therefore, this chip requires more efficient radiator with thin plates for even greater increase in the area, with holes for better ventilation. It's just like a computer processor used to be able to work without radiators, then demanded the presence of radiators, and now require much more complex cooling systems.

That is technically light "Optolyuks" more advanced than "SvetaLED". But why now "Optolyuks" expensive.

Two different approaches to the issue of market penetration. "Svetlana-Optoelectronics" has decided to enter the market with a proven and reliable solution. "OptoGaN" made a bid for the advanced new technologies. Whose strategy will hold true, time will tell.

But the Chinese product. There is no clear conclusion. The one instance that fell into my hands, plain low-quality Chinese artifact, sold at the price of high-quality products. But that does not mean that all Chinese lamps are, as I said, I've seen a more advanced and high-quality copy. But it had to be ordered from China, and how much it will cost us in the market is unknown.
