Measured: Comparison of power consumption, illumination, heat and color temperature data of four smart bulbs

Comparison of four smart light bulbs

In the smart bulbs currently on the market, the connection methods are mainly Bluetooth and WiFi, and the two connection methods are bound to be different in their use, that is, Bluetooth can only be used locally, and WiFi is not subject to distance. limited. However, in terms of application convenience, Bluetooth has an incomparable superiority, that is, no network environment, fast connection, no threshold.


In this project Hengping total of four intelligent lamp participation, they are: LifeSmart Bluetooth lamp, X-Light Plus, PLAYBULB intelligent LED lamp, Yeelight LED lamp (white Edition), based on the WiFi connection in addition Yeelight LED bulbs In addition to not supporting color change, the other three models communicate with mobile phones via Bluetooth and are variable colors.


Let's take a look at the differences between the four smart bulbs in a big picture:



List of four smart bulb comparison tables


Through the above pictures, everyone can have a general understanding of the four products, and the difference between Bluetooth and WiFi connection methods, how to choose in the color conversion, and then will be announced for you.


Analysis of preheating questionnaire before evaluation


Before the start of the horizontal review, the author also conducted an online survey. The number of netizens participating exceeded the author's expectations. I didn't expect the attention of home lighting equipment to be so high, and most consumers knew about smart bulbs, but the demand was not special. Obviously, for the function of light and dark adjustment, it is clear that many consumers have formed a resonance.


And in terms of energy consumption, control, and price of lighting equipment, consumers also give a clear attitude.


Consumers are still satisfied with the existing lighting equipment in the home


In the Internet age, consumers are still very quick to obtain information. At first, the author believes that smart bulb products may not be known to most consumers, but investigations have shown that most users still know about such household lighting equipment. The purchase may be due to a lack of understanding of the product.


Most consumers still know about products like smart bulbs.


For the functional requirements, in fact, the needs of consumers are still relatively uniform, and the light and dark adjustment of lighting equipment has reached an unprecedented consensus!


Bright and dark brightness adjustment requirements are more uniform


Regarding the issue of energy consumption, there has been a one-sided situation. It can be seen that more and more consumers are paying more and more attention to energy, and they are aware of the importance of energy conservation.


More and more consumers are aware of the importance of energy saving


For the control method of smart devices, more consumers still want to be able to remotely control, and the switch is more convenient anytime and anywhere.


WiFi connection is more popular


Finally, the user's attitude toward the price of smart bulb products was also investigated. Nearly half of the users said that they can accept it, but they hope that the price of such products is more affordable. It is not difficult to reflect through the survey results.


Nearly half of the users said they can accept


But I hope that the price of the product is more affordable.


From the above survey results, it is not difficult to see that although consumers buy smart bulb products, there are not many, but basically all have heard, users' needs are basically concentrated on remote control, shading adjustment function, attention to energy consumption and price. . And in the next horizontal review, how the performance of each bulb, let us look forward to it!


Preparation before the evaluation experience bulb connection


Preparation before the evaluation experience bulb connection (UI interface)


As we all know, the smart devices currently on sale need to be bound to smart phones, and the products are controlled by mobile phones. The connection process is simple, and whether the UI interface of the mobile phone is simple or not will have a great impact on the user experience.


To this end, the author will tie the four smart bulbs one by one to the mobile phone and application experience, to see which one is more worry-free.


Four smart light bulbs connect your phone and experience


In the process of connecting these four products, the author is also the first to use the Bluetooth light bulb. This kind of product connection is very simple, unlike the WiFi light bulb, you have to enter the password to match, etc., the Bluetooth light bulb can be directly connected.


However, at the same time, there are obvious deficiencies. The Bluetooth light bulb can only be controlled within a certain range, and does not support remote, so the user should also be targeted in the selection.


1LifeSmart Bluetooth Light Bulb UI Interface


LifeSmart Bluetooth light bulbs require user registration before they can be used


It is very easy to add a light bulb connection by clicking the "+" after skipping the prompt page.


2X-Light+ Smart Light Bulb UI


X-Light+ does not require registration. It is also a Bluetooth light bulb. Clicking on the connection is very simple.


X-Light+ UI interface information is very rich, there are a lot of fun things to play with.


X-Light+ This bulb is more interesting to control. It is the only one of the four bulbs. You can see some bubbles in the app interface. You can make the lights become the same by clicking s color.


It also supports some interactive functions, such as heartbeat test. The APP interface will prompt the user to “cover your finger on the camera and flash”. The heartbeat value can be measured for a while, and the light bulb will also simulate the state of the heartbeat. Flash), but the data is only for entertainment and practical value is not high, but entertainment is still there.


3PLAYBULB smart LED bulb UI interface


This light bulb also does not require registration to open a Bluetooth click-to-connect.


Intelligent LED light bulb control interface


4Yeelight LED bulb (white version) UI interface


Yeelight LED bulbs need to be registered before they can be connected to other smart devices.


Yeelight LED bulb UI interface (brightness and quick operation is still good)


Yeelight LED bulbs are connected based on WiFi. The control advantages are obvious, and the remote control switch can be realized. However, the connection process is more complicated than the Bluetooth bulb, and occasionally there is an inexplicable connection failure.


The above is the full UI interface and product connection process of the four smart bulbs. The advantages and disadvantages of WiFi and Bluetooth bulbs are also obvious. Users can choose according to their own needs.


If you want to choose a WiFi light bulb without being limited by distance, if you don't need a remote and want to connect more easily, then a Bluetooth light bulb is definitely the first choice.


Hard power competition to measure the parameters of the bulb


It is not difficult to see from previous investigations that consumers' energy consumption is an important reference value for lighting equipment selection. Under the premise of meeting lighting requirements, energy-saving equipment is more likely to be favored by users.


To this end, the author separately measured the power consumption, illuminance, temperature, and color changes of the four products, and presented them in front of everyone through more intuitive data.


Functional test of four smart bulbs: rated power, measured power and standby power


Four smart bulbs (including a common LED light) power consumption measured



Through the actual measurement of the functions of the four smart bulbs, it can be seen that the measured maximum function of the X-Light+ and Yeelight bulbs is close to the rated power, while the LifeSmart and PLAYBULB models have a large gap, indicating that the product power is virtual. Target problem.


At the same time, we can see that no matter whether it is Bluetooth or WiFi bulb, after the mobile APP is closed, the device will still have a certain power consumption. If you want to completely power off, you can only use the switch, and the Bluetooth is obviously lower than the standby power consumption of the WiFi bulb. .


Four smart bulb illumination measurements (Note: the same distance and environment test)


Four smart bulbs measured


Before the four smart bulbs are measured, it can be seen that each of the X-Light+ and Yeelight bulbs has a higher brightness, and the measured results can also be shown (it is easy to see through the above figure). For the brightness, each consumer's demand is different, so in the choice, the user still chooses according to their own needs.


Four smart bulbs are measured by heat (the bulb temperature is measured after the same period of time is lit)


Four smart bulbs fever measured


By measuring the calorific value of the four smart bulbs, it can be seen that compared with the ordinary LED bulbs, the smart bulbs have more heat dissipation, and the four smart bulbs are 10°C higher than the ordinary LEDs, while the Bluetooth and WiFi bulbs are Compared to the WiFi bulb, the heat is more obvious. Yeelight reaches 58.6 °C and can hardly be touched by hand.


Four smart bulbs color temperature measurement


Four smart bulbs color temperature measurement


Since the four smart bulbs are not labeled with their respective color temperatures, I only show the measured color temperature of each bulb.


At the same time, it is also necessary to explain to everyone that the color temperature and illumination are different. In simple terms, it is the distinction between cold and warm colors. Like the light bulbs tested, the larger the value, the white light, such as ordinary LED and X-light; The remaining three values ​​are smaller, indicating that the yellow light is warm.



Through the above color temperature meter, I believe that the concept of color temperature will be more clear, and household lighting equipment is generally selected in two kinds of light colors: cool white and warm yellow.


Generally speaking, the living room generally chooses white light because it will look brighter, while the bedroom usually chooses warm yellow light, which looks more warm. But still, the needs of each consumer are different, and the choices must be chosen according to their own needs.


Discoloration or dimming? Four smart bulb evaluation summary


For the color of the lights, many smart bulbs currently on sale support thousands of color changes, which can create a romantic atmosphere for young couples, and is a good choice for users in need.


However, the practicality is not high, but it is still different from person to person. As far as the author's experience is concerned, its practicality is not high, but in life, the role of the adjustment is mentioned. For example, the color of some bulbs can be changed with different music. It may be good for a friend who has an emotional tone.


Among the four smart bulbs, except Yeelight LED bulbs (Yeelight only supports light and dark adjustment), the other three models can support color conversion (also supports light and dark adjustment), below through a few pictures, you can feel it, see Is it suitable for your style?

Frankly speaking, the practicality of the change of the color of the bulb is not high, and in the test process, the color of the six colors of the color has a great influence on the eyes, so consumers can choose according to their own needs when purchasing. Of course, these color changes are just one of the functions. Users can switch freely. It does not mean that only color lights are supported. In fact, it does not have much impact on the use. It is only more expensive than not supporting discoloration.


At this point, this cross-evaluation has all ended. The use of four different bulbs, difficulty level, color temperature, illumination, heat, color temperature, etc. have been measured. I believe everyone has a clear understanding of smart bulbs, and finally The author will also summarize with you.


Light bulb evaluation summary



  • Through the testing and use of four different smart bulbs, I believe that most users have a better understanding of such lighting equipment, and have an intuitive understanding of product features, shading adjustments or different colors of lighting, in the future to buy this When it comes to lighting equipment, it can be more targeted;


  • It can be seen from the measured part that the Bluetooth light bulb has lower standby power consumption and heat dissipation than the WiFi light bulb, but there are also obvious short boards, that is, it does not support remote control, and can only be used within a certain range. All four bulbs support the shading of the light. In addition to the Yeelight LED bulbs, the other three models also support different color switching;


  • Compared with ordinary light bulbs, the control method of smart light bulbs is more flexible, and both support the light and dark understanding of the light. In life, users can adjust different lights according to their needs, and the utility is good. However, it should be noted that the bulbs of different brands are still unable to achieve unified management. In order to facilitate the control, it is necessary to purchase a brand of products in a unified manner when purchasing.



Consumers with pros and cons need to be cautious when purchasing smart bulbs


As far as the author's trial experience is concerned, the smart light bulb has not changed much in life. If you have to say which function is more touching, the author thinks that the light and dark adjustment of the light is more practical, and different needs can be adjusted in a targeted manner. It is convenient.


However, the control mode still relies on the mobile phone, and each light bulb has its own APP software, which undoubtedly limits the choice of the user's brand and the control method is not humanized.


The color change function of the light thinks that it is not necessary. Although this is only an auxiliary function, it has increased the price of the product. If the function is removed or a simplified version is introduced, the user may have more choices. And during the test, due to the change of different colors, the eyes of the person are very uncomfortable, and the practicality in the family is poor.


Of course, during the test, there was also a special understanding through running. The reason is that he wants to turn off the lights. This smart light bulb can definitely help you. For the "lazy", is it a picture? Convenience?


If the user wants to buy, I still recommend to choose a Bluetooth light bulb. Although in the survey statistics, many netizens prefer the light bulb to be connected based on WiFi, but the network connection is not only complicated but sometimes very unstable, often unable to connect or not control. The embarrassment, but the way through Bluetooth is very worry-free.
