Smart light or smart light bulb is not a new thing today when the concept of smart home is popular. But if there is a light bulb that can be controlled without Bluetooth pairing, WiFi connection or zigbee gateway, then I believe it is the first time that most people have heard about it, so today I will share with you an interesting light - Hey Light.

So what the hell is this light? Don't worry, let's just say a few words first. The founder of HEIDIAN is Zhang Lei, a former 360 product consultant, a technology craftsman who has worked in hardware and software. He created such a unique lamp, although there is no Bluetooth WIFI、zigbee， Hey, the lamp is not a black technology. It's a digital voice controlled bulb! It sounds very mysterious and wonderful to use, but it is actually very simple.

The packaging of HEILIANG is very simple. It is no different from all bulbs. It is all made of corrugated paper boxes, but it is black, surrounded by product maps or logos, or two-dimensional codes, or product parameters... In short, there is everything you want to know. Hey, the lamp supports 2700K color temperature - 5600K color temperature adjustment, with a power of 6W, and the interface is a common interface of E27,

Hey, light! One of the biggest highlights is code scanning and control! So naturally, there is no code.

The overall packaging design is indeed similar to all LED bulbs sold on the market, and does not show much pressure, but this simple attitude shows that this product is very friendly and grounded. Dynamic drawing unpacking:

The accessories are also very simple, light bulbs and two QR code stickers. One is ON, and the other is OFF. It should be used to turn on and off the lights.

The material of Heideng obviously continues the process of traditional bulbs. The light cap of Acrylic is printed with the word "Heideng"!

The abdomen is made of plastic coated aluminum, which is insulated but durable, and the surface is coated like frosted particles.

Since it is voice control, it is different from ordinary light bulbs in that it requires an additional microphone to pick up sound. It is hidden in the spiral mouth of the bulb.

Hey, the shape of the lamp belongs to the slender type. It is still a little protruding after being installed. If it is only used as an ordinary light bulb, its brightness will default to maximum. Well, we'd better scan the code and control it.

After scanning the code, we can open an H5 page, and we can successfully control the HEILIANG, including brightness adjustment, color temperature adjustment, switch and other operations. HEILIANG has 10 levels of brightness adjustment and 5 levels of color temperature adjustment. On the control interface of the page version, we can also see two access ports for APP download and purchase.

Hey, the principle of the light is to interpret digital sounds. All operation instructions are compiled into dozens of sounds. Through this customized sound (about 1 second in duration), you can complete operations such as switching, brightness adjustment, color conversion, etc. This voice is not a traditional voice, but a similar bird call. Although the author sounds little different, the instructions are quite different. The compatibility is good, both Android and IOS can be used. In addition to page users, they can also download the APP. In the APP, we can control multiple bulbs in three groups: A, B, and C. The control is extremely simple, and there is almost no cost of learning. It can be easily learned at a glance.

We can see some differences between the actual effect of the light and the color temperature. Here are some pictures of warming and whitening.

If you don't have a friend of HEIDIAN, you can also buy it directly. At present, the price is 49 yuan. But Mr. Zhang Lei, CEO of HEIDIAN, said in an interview that he hopes to make the monochrome HEIDIAN 19 yuan or even lower. With the optimization of the circuit and the improvement of the integration, the HEI lamp will sell for 9.9 yuan in the future. If this is true, I think it will be invaluable.

Finally, let's talk about Heideng's red and black chronicles:

There is no doubt that the creativity of HEIDENG must be praised, which breaks away from the previous connection mode and makes the experience different. HEIDENG can at least avoid the embarrassment of connection failure. And relatively speaking, the price advantage is also obvious. Compared with hundreds of smart bulbs, HEILIANG is reliable.

But Hedeng also has several small embarrassments. One is scanning the code. Although there is no need for networking, scanning the code still needs networking... If you download the APP, it will be convenient to scan the lost code, and then the problem comes. Although we won't always have the QR code with us?

The second is the adjustment of brightness or color temperature. Although there are 10 levels of brightness adjustment and 5 levels of color temperature adjustment, in fact, there seems to be little difference between the middle levels, sometimes even no difference. There is also a problem with the memory. When the power supply is cut off and restarted, the brightness will be automatically adjusted to the maximum, and the setting cannot be memorized.

Thirdly, the sensitivity of voice control. Maybe because of the airtightness in the lampshade, the inflexibility of voice control operation is not as high as expected. When the mobile phone is a little far away, the operation will not respond. But most of our table lamps cannot be without lampshade.

Finally, the voice controlled audio seems slightly strange, birdlike and not so pleasant, and we often turn up the voice for high recognition, which easily affects people around us.

Of course, this is a very creative product anyway, and it is also very practical. Hey, this lamp is really good.
