I still remember when I was a child, when I just installed voice control lights in the corridor, I always ran to each floor after school with my friends, and stamped the ground hard to make the lights in the corridor light up. We were scolded for this, but we still enjoyed it. It was not until the acousto-optic switch was installed later that we stamped our legs numb and the light did not light up when school was over that we became less noisy.

About the third grade, we also installed voice control lights at home. More specifically, we installed a voice control switch. The voice control switch is connected to the socket, and the plug of the desk lamp is connected to the voice control switch. Keep the switch of the desk lamp on all the time, and you can control the switch of the desk lamp through the sound of clapping. However, it took about two or three months, Several voice switches at home are broken one after another. The light doesn't light up even when the hand is swollen, or it lights up by itself without any reason. The quality is worrying.

Nowadays, with the development of intelligent hardware, smart home has also begun to appear in people's vision, and smart light bulbs are no exception. However, simply controlling the switch by voice can no longer meet people's needs. So this kind of light that can control brightness and color temperature may be your dish.

1、 Unpacking&Appearance

The simple packaging is my first impression of HEILIANG. On the front is the appearance picture of HEIDENG, and on the back is the website and logo of HEIDENG. The simple packaging of black and white seems to express that this is a product that will go into thousands of households to replace traditional bulbs.

On the side of the box are the parameters of the QR code and the HEILIANG. After scanning the code, you will go to the official website linked to HEILIANG, and adjust the switch, brightness and color temperature of the HEILIANG on the webpage. However, either there is wifi or the traffic is not enough, or I recommend downloading an app. E27 interface is suitable for most lamp holders at home; LED light source, 6w power, warm white dual color, brightness of more than 600lm and life span of more than 5w hours, all enable HEILIANG to serve as a household task.

After opening the package, Hei Deng and two QR code stickers are the things that can be taken out of the whole box. Of course, there is also a corrugated lamp holder in the box, just like the simple outer package. The two QR code stickers have different functions. Scanning the QR code with "ON" will connect to the control interface on the web side and give an audio indication of turning on the light. The brightness will be turned on to the maximum. Scanning the QR code with "OFF" will naturally turn off the light.

In fact, at the beginning, I only knew that Heideng was a smart light bulb. I thought it would be controlled by wifi or Bluetooth connection. It was useless to click after scanning the code to connect to the control interface on the web side. At the beginning, I thought it was because the light bulb was broken or you had to pair it with an app first. When I knew that I had downloaded the app, I shed tears when I knew the truth... Let's take a look at the app.

2、 App experience

Although HEILIANG doesn't need to connect to wifi or Bluetooth, if you control HEILIANG with the web terminal, your mobile phone will have to be connected to the Internet, so let's go to the next app honestly. The client installation package is not small, probably because it stores multiple sounds.

After opening the app, I finally know why I can't control the HEI light with the web terminal. It turns out that the foreign side of my phone has turned off... No wonder the box says that I should turn my phone to the appropriate volume, meaning to turn it up.

The control interface is a bit like the dial of an old telephone. When the number is turned clockwise, it will become larger and counterclockwise, it will become smaller. With the change of the number, different sounds will be made to control the brightness of the bulb. But sometimes there is no sound when it is rotated. At this time, clicking the middle number will repeat the sound. The bottom four keys control the switch of warm white and light respectively.

The app can remember three groups of light bulbs. Click the settings in the upper right corner to clear the group information, but so far we have not understood the usefulness of this group, because we cannot remember the brightness of each group separately. Maybe only one light bulb causes the app to be arrogant and not give you the right to control multiple groups~

The app is still very sophisticated. The light bulb brightness indicator on the turntable will be different when the brightness level is different, but I still have to complain about one thing. It will stay in the notice bar! I know this is for the convenience of controlling the light bulb, but it's OK to turn off the notice bar. If this can't be turned off, what's the difference between this and the rogue software like big numbers

Really, I finally know where the icon on the package box will appear. Is this really a sundried jellyfish like icon on the notice board? Of course, it will disappear after restarting the phone, but as soon as you turn on the Hedeng app, it will come back again, and cannot be turned off after exiting the app

3、 Use experience&brightness test

Because of the E27 interface, it is very convenient to replace bulbs. The bulbs at home are basically of this interface. Next, let's look at the brightness under warm white. First of all, let's take a look at the environmental photos under the natural light. More than three o'clock in the afternoon, on a cloudy day, I closed the curtains of the room.

Let's first look at the brightness levels of warm colors.

It can be seen that the brightness changes between Level 1 and Level 2 are relatively obvious, and the transition of brightness changes between other levels is relatively smooth. Next, let's look at the changes of brightness at different levels under white.

It is similar to the warm color. There is a clear difference between the level 1 and level 2 brightness. The brightness changes between other adjacent levels are smooth. In fact, I think it is very likely that the human eye can still look at the bulb directly when the level 1 brightness is high. If the brightness is higher, the human eye will be uncomfortable looking at the bulb directly.

Because of the use of LED light source, the HEI lamp is brighter than the energy-saving lamp of the same power. Therefore, although the power is only 6w, the lighting effect is about the same as that of the energy-saving lamp of 10w. It is enough to be used as a desk lamp on the bedside or desk. After using it for a period of time, the heat of the lamp base is obvious. In addition, it is better to hold the base instead of the bulb when installing it, otherwise the bulb cap is easy to be screwed loose.

4、 Summary&Suggestions

As a household light bulb, it is easy to change, has enough brightness, and can also adjust the color temperature, which is very attractive to people like me who don't like the pale color of energy-saving lamps. Looking at the evaluation of other websites, we found that the price of this warm white dual color LED lamp will be around 20, which seems to be the same as its appearance. It is mainly people friendly. Under the same price as the same power energy-saving lamp, even without warm white dual color and brightness adjustment, trusted consumers will choose LED lamps with longer life and better brightness.

However, the voice control of HEILUN is not convenient enough. As a lamp, what we need most is that we can easily turn on the lamp in the dark. When you get up at night and go to the toilet, you will pull out your mobile phone first app Turn on the light again? I think the switch of the hey light can change the voice control command, just wake up google Search, say “ Hey, light ” It may be more convenient. Secondly, scan the QR code on the sticker and turn on the light. The default is the highest brightness, which is a bit harsh. I hope the default brightness can be reduced a bit, so it will be a little more warm.

Finally, the question came, hey, who is the cartoon character beside the lamp?
