Recommendation 1: no stroboscopic hazard, no blue light hazard
The flicker of light is what the naked eye perceives. When children are studying in this environment for a long time, their eyes will be greatly damaged, which not only causes myopia, but also reduces their concentration. The blue light here refers to the short-wave blue light with a wavelength of 400 to 450. The blue light within this wavelength will increase the amount of toxins in the macular region of the eye, which seriously threatens the health of children's fundus. So pay attention to whether there is stroboscopic or blue light hazard when purchasing the learning desk lamp.

Recommendation 2: The higher the standard, the better
Illuminance can be simply understood as the light intensity of a light and the light uniformity within its illumination range. There are international requirements for illuminance and illuminance uniformity, and table lamps are divided into Class A and Class AA. Our best choice is a table lamp with AA grade, wide effective lighting area and uniform lighting.

Recommendation 3: Color rendering index>90
Color rendering index refers to the authenticity of the color of the object under the light source. The most standard reference is the color of the object under the sun. 100 Ra is the full mark, and 80 Ra is passed, but we'd better choose the lamp above 90 Ra for children's study.

Recommendation 4: Color temperature can be adjusted according to demand
Color temperature refers to the degree of heat and cold of the light. Different use scenarios should be matched with different color temperatures. The color temperature of cold white light is about 5000k, which is suitable for concentrated learning; The middle color temperature is about 4000k, which is suitable for long-term screen reading; The warm color temperature of about 3500k is suitable for use 1-2 hours before going to bed, which helps to improve the quality of sleep. Therefore, it is best to choose the adjustable color temperature when learning to buy table lamps.
