Practical Q&A
Question: How to choose the power and color temperature of the ceiling lights brands?
Answer: According to the mainstream rough estimate of 70-80lm/w light efficiency, follow the recommendations to meet the basic brightness of the home without pressure.
Living room: 4-5W/square meter
Bedroom: 2-3w/square meter
Restaurant, kitchen: 5-6W/square meter
In order to make the lighting effect more coordinated, it is recommended that the same type of lighting source in the same space use the same color temperature.
If it is a fixed color temperature ceiling lamp, it is recommended to be 4000K or below.
Nowadays, almost all ceiling lamps come with dimming and memory functions as standard, so there is no need to worry.
For the problem of over-brightness, it is more practical to buy stepless dimming for bedrooms than three-stage dimming.
Question: How to choose color rendering index?
Answer: Of course, the higher the better, the ceiling lamp is a basic lighting fixture.
According to the national standard Ra>80, R9>0 can meet most home needs.
Therefore, the CRI of many large circulation brands is still based on the national standard line. If you have a budget Sufficient, studios, studios, and children’s rooms can use ceiling lamps with high color rendering properties.
Better light quality
High-quality light sources can indeed play a big role in specific scenes, such as painting, makeup and other tasks with high color requirements.
They are also more comfortable for daily use. This is why we buy high-color rendering lamps or full-spectrum lamps for grounding.
Reasons to be angry, not gimmicks such as “eye protection”.
If you care about color rendering index, purple LED is currently the first choice. It has low spectral missing rate, high continuity, small color tolerance, gentle spectrum, no obvious troughs and peaks, and the spectrum is closest to sunlight.
For example, the pictures below are both 4000K and Ra>96 high color rendering LED lamps. The difference can be clearly seen from the spectrum.
Some lights have a high apparent color index, but the color is still dim under the light.
This is probably because only Ra is marked, and Ra is the average of R1-R8.
This part mainly represents the reducibility of light colors. For example, R12 in the picture below is only 70 +.
If you really care about the CRI, don’t hold on to Ra.
You need to look at the spectrum, CRI, Rg/Rf, and color tolerance.
Red apples and red strawberries are commonly used by e-commerce companies to describe the CRI.
Not reliable, the simple and reliable way is to buy purple LED.
Q: What are the common ways of emitting light from ceiling lamps? What are the pros and cons?
Answer: Direct lighting, light guide plate side lighting, linear silicone lampshade
Q: What are the advantages of light guide plate ceiling lamps over traditional ceiling lamps?
Answer: It is thinner, about 2cm, compared to the traditional ceiling lamp, which is about 10cm.
More comfortable. Compared with the direct downward emission of traditional ceiling lamps, the side emission of the light guide plate is softer.
More beautiful, simpler and more durable, and less likely to become outdated.
It’s more worry-free. It’s a metaphysics that traditional ceiling lamps won’t let mosquitoes in. It’s science that light-guided ceiling lamps won’t let mosquitoes in.
More expensive means you are rich
Question: Which direct-emitting ceiling lamps have advantages over light guide plate ceiling lamps?
Answer: The direct-emitting light source/power supply is modular.
You can change the light source by yourself by removing the lampshade.
The maintenance cost is extremely low. Non-professionals cannot handle the light guide plate.
Linear silicone lampshade: The most commonly used method for linear surface ceiling lamps, which can create a linear feel and is slightly dazzling. The thickness of the conventional lamp body can be about 6cm.
Q: How long is the service life of a ceiling lamp?
Answer: Generally, the service life of the brand’s LED lamps is 15000h~25000H+. According to the usage frequency of 8 hours a day, there is no pressure for more than 5 years. For lamps with high positioning, there is no pressure for 10 years+ (usually with low light efficiency). I have said it a hundred times and come with it. Please buy brand-name lamps and lanterns for light sources. Even if they are brand-name lamps and lanterns, you must purchase brand-name light sources.
The commonly used L70 standard, that is, the time it takes for the light to decay to 70% is considered a defective product, not a dead light.
Question: How to choose the size of the ceiling lamp in the living room?
Answer: It is more appropriate for the lengthwidth of the lamp and the lengthwidth of the ceiling to be 1:5. For example, if the living room is 5M3.5M, the lamp should be about 100cm70cm. It is for reference only.
Question: What is the mainstream price range for ceiling lamps?
Answer: Taking three bedrooms and two living rooms as an example, usually 2-3K is the mainstream budget. No matter how expensive the ceiling lamp is, it is either a brand premium, a difference in model, or an improvement in light source, material, workmanship, and function. It can be purchased as a set. Don’t buy them separately, you can save a lot.
Question: There are many big brand ceiling lamps online that are very cheap. Can I buy them?
Answer: Of course you can. If your pocket is tight, the running models of various brands are almost the best solution, but don’t ask for too much. If you have high demands, please top up.
Why?
- E-commerce competition and volumetric energy stores cannot even think about it. Sales volume of 10W+ for a single model is common in e-commerce, but entities cannot even think about it. Each brand has its own high-volume models to gain attention, and merchants’ profits are very low. , even lose money and make money during big sales, relying on high unit price lamps to make profits.
Large quantities lead to advantages, single product sales often start at tens of thousands or hundreds of thousands, and one production line only produces one lamp. No matter how low the cost is, the mold opening cost spread equally to each lamp is almost negligible.
Is the quality poor?
-Won’t
Today’s LED light source technology is very mature. The design service life is basically 15000H~25000H or more. If the light is used for 8 hours a day, the average maintenance frequency will not be less than 5 years, and the average defective rate will not be higher than 1%. Otherwise, the manufacturer Likely to lose money.
In terms of light source: there is no problem if it is qualified, and many ultra-cheap lamps have a color rendering index of over 90. LEDs and driving power supplies are too mature and popular.
In terms of materials: it is indeed “saving”, but rarely “stealing”.
Q: The line-surface series ceiling lamps are much more expensive. What’s the price difference? Is it worth it?
Answer: The price difference is mainly due to the model. Small sales volume, high assembly costs, and high single-mode costs are all reasons for the high price. From the perspective of the lamp itself, the premium is higher than the value. From an aesthetic point of view, it is worth spending a few more dollars. In other words, buy something that looks good.
Question: What kind of style will not go out of style easily?
Answer: The simpler and classic the model, the more eye-catching it is. The more flashy and internet-famous the model, the shorter the life cycle. The style of lamps changes every year. It is impossible to decorate your home every year. Classic models are the best to buy. main direction.
Q: Any recommendations for brands of ceiling lamps?
The price is recommended for a three-family room (only suitable for traditional ceiling lamps that emit direct downward light)
➀ If you care about cost-effectiveness (0.8-2K), please refer to major domestic circulation brands such as Opple, NVC, and Sanxiong.
➁ If the budget is not bad (around 2K), please refer to Panasonic and Philips
➂ If you care about precision workmanship and light source comfort, choose Berman (5K watch)

New products this year
1) NVC full spectrum
NVC has a very rich product line. In recent years, it has made major upgrades in light sources. From ceiling lamps, downlights, to floor lamps/table lamps, Ra97+ high-quality light sources with high color rendering can be seen everywhere.
What’s more important is that while upgrading the light source, it is also very cost-effective and makes a “good lamp that everyone can afford.” This is a down-to-earth thing.
For example, NVC’s Ideal Light (Guanghua) series downlights
The deep cup design not only prevents glare, but also has a large beam angle of 90° for more uniform illumination.
- There is also an ultra-high color rendering index of nearly 98
- The key is more than 40 yuan, which is very cost-effective.
For example, NVC small white ceiling lamp
You can get the 5-light package for 1K+. It is a Mijia smart ceiling lamp with Ra97 high color rendering, CQS98 high light source parameters, airtight lamp body, and anti-mosquito. (will be mentioned later)
For users who pursue higher standards, NVC also has ceiling-mounted ceilings from the Future Light series.
NVC future light
- The entire series comes standard with Ra98 high color rendering, CQS98, RG0 blue light level, and exemption level strobe.
- Bright, very bright. The entire series is very bright. The luminous flux of the living room lamp is 8000+lm. Even a 30-square-meter living room can easily be filled with bright and soft light. “Eye protection” should be uniform illumination over a wide area.
- “Not dazzling”, the prism lens spreads light evenly and can effectively alleviate glare. Even under such high brightness, it can still reach UGR ≤ 19.
- Light guide plate design, preventing mosquitoes is not a metaphysics but a science.
- The lamp body is slim, simple and versatile, and the metal ultra-thin lamp body has a delicate texture.
- It is all Mijia ecological products, which is more conducive to linkage with other ecological products, and the price/performance ratio is also high compared with the same period last year.
2) lipro E2 ceiling lamp
Important upgrade
1️⃣Continues the excellent quality of “Ruran Light” which is close to sunlight.
2️⃣Ecological upgrade, opening up the Mijia ecosystem on the basis of Lipro Smart Home, HomeKit, and matter.
3️⃣Brightness upgrade, the brightness/power of the same type of ceiling lamp has been greatly improved, and it is “not dazzling”.
4️⃣Color temperature upgrade from 3000-4000K to 3000-5000K.
5️⃣ Dimming upgrade, optimized power performance, and smoother and more delicate dimming.
6️⃣Material upgrade, the metal lamp body has better texture and stronger thermal conductivity.
7️⃣Quick installation upgrade, optimized quick installation base, making installation more convenient.
Readers who often read my articles know that I have been recommending this brand and have never been disappointed.
The light source from head to toe is purple LED, with low blue light, low color tolerance, high color fidelity, and high color rendering index CRI90+. Ra97+, the light source quality is undoubtedly top-notch.
I’m talking about him alone today because HomeKit, Mijia, and Matter have finally arrived.
The boasts I once boasted about have finally come true, and I won’t call him an abortion expert anymore.
Each product has an original design and can think from the user’s perspective.
The round ceiling lamp is only 2.16cm thick after installation.
The materials and craftsmanship are unambiguous from the inside to the outside. Although the price is not cheap, judging from the comprehensive products , the price/performance ratio is still there.
3) Berman rohm S1/A1/L1
I bought Rohm. It was really untimely. Just one month after receiving the goods, it was said that it had been upgraded to full spectrum.
I didn’t confirm with the official whether it was a purple LED (I don’t know if it was true). Ten thousand ants were floating in the sky, but Judging from the data I tested before, the light source has indeed improved a lot.
Now the official announcement is
Regardless of the light source, this lamp is also very good. It has an all-metal body and is full of weight.
You can tell it is a Berman lamp at a glance.
It is also very recognizable. Moreover, Berman has launched a 10-year performance warranty, which is very good in the lighting industry.
This is the first of its kind, and this is the attitude that an established international lighting company should have.
Both rectangular living room lights and round bedroom lights are available
4) Honeywell ceiling light
It’s not considered a new model, it’s just listed here with the ones in the same price range for your convenience.
Bright, very bright, the ideal light living room lamp is 8000lm, the natural light (direct light) is up to 9000lm, oh my…
Someone asked, compared with natural ceiling lights brands, ideal light has higher power but lower brightness?
-Lamps with high color rendering often have to sacrifice brightness. Ideal light is side-emitting and has a lower utilization rate. It is normal for high power and low brightness.
It is also a very good lamp, and it is still highly recognizable. The brand’s 13 grids are also displayed here.
Some people say that there are “water ripples” when taking photos of Honeywell lights with a mobile phone, and they say there is a stroboscopic hazard.
Let me tell you: No, no, no. There is no risk in using a stroboscope to measure it. Photographing with a mobile phone is unreliable. I didn’t see any “water ripples” in the photos taken with my mobile phone.
The lamp is a good lamp, but I personally don’t like putting the logo on the luminous surface. It feels a bit forced to watch an advertisement.
5) yeelight light guide slim/mix
Yeelight is very familiar. It is the mainstay of Mijia’s ecological lighting section. Its products have good value for money. After the ultra-thin ceiling lamps in the first half of the year were overturned, slim mix is here. It has all the functions that Mijia has.
Showdown: This lamp is very popular, and I am also riding on the popularity of this ceiling lights brands. I am too busy during this period and really don’t have time to do it. I will also use the cloud for the time being. The feedback from friends is not bad. According to the urinary properties of yeelight, it should be No big deal.
Let everyone identify it by themselves
Pick up missing items
If your pocket is tight, the high-volume models of various brands are almost the best solution, just buy indiscriminately with your eyes closed.
During big sales, they are all used to make money. The price-performance ratio is very high. Usually, a whole house can be purchased for just a few hundred yuan.
You can enjoy the quality and service of big brands at the price of other brands, but don’t ask for too much, especially Workmanship, please top up if you have high requirements.
The budget for the whole house is only 0.5K-1.5K, and there are high-volume models, cost-effective models, and high color rendering models. Take a look here:
Simple ceiling lamp
The price refers to the approximate price of a three-bedroom apartment
1) NVC Snow ceiling lights brands
Everyone calls him a little white light, Ra97 high color rendering, CQS98 high light source parameters
The lamp body is airtight, anti-mosquito and insect-proof
Back-plug quick installation, the whole lamp can be taken off for cleaning, and can be easily put back on, light and convenient
The lights in the living room and bedrooms all come standard with Mijia smart lights.
You can get the 5-light package for 1K+
2) yeelight Lingxi (within 2K)
A very classic model. The package price last year was 2K+. I tested the ceiling lights brands last year and the color rendering index was Ra95. According to the official website, the light source has been upgraded to “full spectrum” of Ra97. In theory, it is better than the original one. Well, even without upgrading the light source, the price is well worth it.
Lingxi has launched a back-mounted tri-proof light this year. It’s up to you to choose. Here are some suggestions.
How do you choose an individual?
3) Three male Aurora Haoyu (within 2K or less)
The main ceiling lights brands is less than 1K. It is very cost-effective and has a good light source. I have recommended this light to several Zhihu influencers through private messages and bought it. After using it, they all say it is good and the most important thing is that it is cheap.
If you still want to be cheaper, you can choose the cloud wing set for bedroom lights, which can be done for more than 1K for the whole house.
4) yeelight fiber jade (around 2K)
I have talked about this lamp thousands of times. It is a very classic model of Yeelight. It used to have daylight algorithm, but it has been castrated long ago. The reduction of configuration is probably to widen the gap with the new model, so that the new model can be pushed away more easily. I have seen crowded For toothpaste, there really isn’t much to squeeze out.
The color rendering index is 90+, the materials are solid, and it comes standard with Mijia smart control, Atom switch, dimming and color adjustment, and the lamp is quite good.
Last year, a three-bedroom, four-light package cost just over 2k. This year, it only costs a few thousand yuan, a discount of several hundred yuan. It is still worth buying.
5) Philips Yixuan ceiling lamp (1K+)
The lampshade is minimalist, the alloy frame is made of solid materials, and with a luminous flux of 120W 8300lm, it is easy to handle more than 30 square meters with one lamp. The size of 970*650 is too large. The softer light under the same brightness is also the benefit of the large light-emitting surface.
Wide color temperature, the lowest color temperature is 2700K, the highest color temperature is 6500K.
CRI, Ra80+, passed.
Ultra-thin? The thin frame does not mean the thinness of the whole ceiling lights brands. The whole lamp is 9cm and the frame is 2.8cm.
intelligent? You can travel all over the world with one remote control. Fortunately, it has 4 preset lighting modes, including sleep mode and delayed lights off function, so you can finally find some comfort.
Why do you recommend this lamp?
What the picture shows is that it is durable and has low failure frequency. It is a cost-effective model from a long-established lamp company. Don’t expect any bells and whistles and eye-catching parameters. This lamp is more suitable for you who want to be worry-free, simple and pragmatic.
6) Midea natural/s (1.5K-3K+)
As you can tell from the name, the main selling point is the light source. A light source that can reach Ra98 is indeed good, but the blue saturation of R12 is in the upper 80s at any brightness and cannot reach 90.
Overall, the ceiling lights brands source is already very good. It’s just that the manufacturer doesn’t want to tell you. I’ll tell you, that’s all.
I think the main selling point of this lamp is not the quality of the light source, but the light guide plate. The light produced by this method is very uniform.
This lamp has good brightness, and the prism lens guides the light evenly, making it bright and not dazzling.
Well, the S is meant to lower the price. It has a plastic shell, lower brightness, and smart control. If you want to be cheap, have a good light source, and don’t have any requirements for texture, choose S.
