Help consumers choose eye-friendly table lamps scientifically
recently
Zhejiang Provincial Consumer Rights Protection Commission
Cooperate with Wenzhou Consumer Rights Protection Committee
Wenzhou Lucheng District Consumer Rights Protection Committee
Carry out a comparative test of eye-protecting table lamps
Sample condition
The 10 samples in this comparative trial were purchased by consumer rights protection volunteers as ordinary consumers, of which 6 were randomly purchased in different physical stores in Wenzhou and 4 were purchased through e-commerce platforms, involving 9 brands and 8 production enterprises.
Price: from 55 yuan / piece to 380 yuan / piece.
All samples are either nominal or claimed
"Eye Protection", "Learning Xi", "National Standard AA Level"
It is understood that GB/T9473-2022 "Performance Requirements for Reading and Writing Desk Lamps" will be implemented on January 1, 2024, considering that the products of some enterprises have been designed and produced according to the requirements of the new version of the standard, so this comparative test is based on the old and new standards GB/T9473-2017 "Performance Requirements for Reading and Writing Desk Lamps" and GB/T9473-2022 "Performance Requirements for Reading and Writing Desk Lamps". Color rendering index and other items are tested.
Retinal blue light hazards
👉 Retinal blue light hazards are the key indicators of eye protection desk lamps, and ignoring retinal blue light hazards is also a basic requirement.
The results of this comparative test show:
Retinal blue light hazards of 10 samples
All meet the requirements of RG0
There is no risk in terms of retinal blue light hazards
👉 Fluctuation depth and transient light artifacts, commonly known as "light source strobe", are one of the important indicators of the performance of eye-protecting desk lamps.
The results of this comparative test show:
Fluctuation depth of 10 samples
All meet the "No Significant Impact" rating
That is, the strobe of 10 samples
There is no negative impact on consumers
Among them, the 3 samples of PHILIPS, NVC Lighting, and Xiaomi have slight fluctuations at the minimum brightness, but they also belong to the "no significant impact" level, and the other 7 samples have no fluctuations and no impact on the maximum and minimum brightness.
The results of this comparative test show:
"Chromatic properties" of 10 samples
All meet the standards
It is worth noting that the LED lamps with adjustable color temperature are more friendly to people who are sensitive to the cold and warmth of the light, and the flexible color temperature range of the table lamp is between 2300K and 6400K, and it is more comfortable to adjust the color temperature to below 4000K at night.
Sample testing information of 10 types of eye-care table lamps

Illuminance and illuminance uniformity
👉 Illuminance and illumination uniformity is one of the important indicators of the performance of eye-protecting desk lamps, and the standard requires that the maximum horizontal illumination of the lamp should not exceed 2500lx in the normal working position claimed by the manufacturer and the gear or range suitable for reading and writing operations.
This comparative trial found that:
The 10 samples were declared to meet the requirements of the national standard AA
After the actual test
9 samples meet the requirements of national standard AA
Among them, the overall illumination of the samples of the Yangmei brand is insufficient
Does not meet the requirements of the new and old standards
The uniformity meets the requirements of the old standard
However, it does not meet the requirements of the new version of the standard
👉 Electrical performance mainly refers to power and power factor, the standard requires that the measured power should not exceed 110% of the rated input power, and the measured value of the power factor should not be 0.05 or more lower than the nominal value, of which the power is greater than 5W and not more than 25W for the table lamp, the nominal power factor should not be less than 0.5, and the power greater than 25W for the table lamp, the nominal power factor should not be less than 0.9. In the case of the same illuminance and illuminance uniformity, the smaller the input power, the better.
The results of this comparative test show:
The rated power of the 10 samples is in
Between 10W and 15W
In addition to the samples of the Yangmei brand
The measured power of the rest of the samples meets the requirements of the standard
The power factor of all samples meets the requirements of the standard
👉 As an explanation of the overall situation of the product, the "mark (mark)" is the main evidence for consumers to purchase and use the product, and it is also an important basis for consumers to safeguard their legitimate rights and interests.
In this comparative trial
品牌为Panasonic的样品
Meets the requirements of the new 2022 version of the standard
PHILIPS、漾美、雷士照明的样品
Some of the product information required by the standard is missing
It does not meet the requirements of the old and new standards
The remaining 6 samples are compliant
Requirements of the 2017 version of the old standard
However, the instructions for use have not been revised
Consumer Experience:
In order to understand the perception and feelings of consumers more intuitively, this comparative test recruited 8 underage consumers aged 9-14 through the Internet to evaluate the comfort, function and appearance of 10 eye-care table lamp samples.

Consumption tips
Emphasizing that AAA is misleading
Zhejiang Provincial Consumer Protection Committee reminds consumers
When shopping for an eye-friendly table lamp
The following points should be noted
👇👇👇
📌 Instructions for use are important. When purchasing an eye-friendly table lamp, consumers should pay attention to whether the instructions (markings) of the product are complete and accurate.
📌 It is necessary to understand the standards. At present, in the "illumination and illumination uniformity" of the eye-protection desk lamp, the national standard is divided into only grade A and AA grade, and the eye-protection desk lamp of some network platforms claims to meet the requirements of AAA, and the so-called AAA grade is only the quality grade certification proposed by the local LED industry standards alliance, emphasizing that AAA grade is suspected of misleading consumers. As long as it can meet the national standard GB/T9473 "Performance Requirements for Reading and Writing Desk Lamps" AA level eye protection table lamps, consumers can buy them with confidence.
📌 Science comes on demand. When consumers choose an eye-friendly desk lamp, in addition to paying attention to the optical performance and appearance design of the product, they can also pay attention to the additional functions of the eye-protecting table lamp, such as adjustable color temperature, light and dark, Wi-Fi control, timing, built-in rechargeable battery and other functions.
📌 Rational protection of rights by retaining vouchers. If there is a consumer dispute or illegal clues, they can make complaints and reports by calling the 12345 government service hotline and the national 12315 platform to protect their legitimate rights and interests in accordance with the law.
