The eye-protection stands were most suitable with 25 watts. If the wattage of a typical desk lamp is too high, it will consume a lot of electricity and be dangerous. A desk lamp with too high wattage can easily overheat, so you won't feel good about using it.
So I recommend a 25-watt desk lamp, a 25-watt table lamp with enough lines. And security is less power-intensive, you think about it.

18 watts moderately. Note that it is better not to buy a Potz lamp.

The eye protection table lamp AA level is good.
National AA level is a very important division of the illumination of the table lamp, which means that the illumination and uniformity of the table lamp have reached the highest standard, representing the comfort and safety of the human eye. According to the national standard "Performance Requirements for Reading and Writing Desk Lamps", the illumination level of reading and writing desk lamps is divided into Class A and Class AA, with the point where the light output surface of the lamp is vertically projected to the desktop as the center of the circle, and the 120° sector area is less than 300mm.
The illumination of national A class should be greater than 300lx, and the illumination of national AA should be greater than 500lx; The illumination of the 120° sector ring belt greater than 300mm and less than or equal to 500mm shall be greater than 150LX for national A grade and greater than 250lx for national AA grade; Their illumination uniformity is less than or equal to 3, uniformity is the ratio of the maximum illuminance to the minimum illumination in a certain area, the smaller the ratio, the more uniform the light, the more comfortable the human eye, the more protective the eyes.
Therefore, it is necessary to buy AA grade table lamp, which represents the best illumination and uniformity.
Precautions for choosing a table lamp:
First of all, understand the concept correctly, "don't let the promotional selling point be a function". The state has not issued specific standards for "eye-protecting desk lamps" or table lamps with nominal eye protection functions, and the relationship between eye protection and table lamp performance has not been strictly demonstrated, and the "eye protection desk lamp" claimed by merchants does not necessarily have eye protection functions.
The second is the misunderstanding of no strobe source. One of the selling points of the eye-protecting table lamp is the lack of frequency and filial piety. In fact, it is impossible to have no flicker in the absolute sense, most of the eye-protecting table lamps are by increasing the flickering frequency of the light source, so that the eyes can not distinguish, in fact, the strobe still exists, and even the high-frequency flickering lamps will affect health if they are used at close range for a long time.
Third, the higher the brightness value, the better. Brightness is a factor that many consumers consider when choosing a desk lamp, in fact, the brightness is not the higher the better, the higher the brightness, the more obvious the glare, and the eyes are prone to discomfort.

Generally speaking, 25w-45w incandescent lamps are most suitable. Most of the table lamps on the market use 40 watt or 20 watt fluorescent lamps, which can effectively ensure the lighting effect of 400-700 lux. Most children's table lamps use energy-saving lamps of about 30 watts or 12 watts, and the color temperature is between 4000K-4500K.
The power of the bulb should also be appropriate. If the power is too low and the light is too dark, it can cause visual fatigue and even lead to myopia. However, if the power of the bulb is too high and the light is too strong, the light will reflect through the paper into the eyes and cause glare, which is not good for the eyes and head.
When using a table lamp, pay attention to the direction of the table lamp, the correct place is the left front or directly front of the person, and avoid placing it on the right side (if you are left-handed and write with your left hand, then the table lamp should be placed on the right). Pay attention to the desk lamp when you are on to read and write, and at the same time turn on the background lighting. Generally, there are ceiling lights or downlights in the room, and the purpose of turning on the background lighting is to improve the uniformity of the illumination of the space and improve the comfort of the eyes.
Ideal for lighting2. Desk lamp style: It is best to choose a table lamp style that does not directly irradiate children's eyes and is fixed.
3. Brightness of table lamp: 40 watt bulb or 20 watt fluorescent lamp can be used for table lamp to achieve illumination of 400-700 lux.
4. Reduce light and dark differences: When children are learning, they should not only turn on the table lamp, but also turn on the lights in the room, which can reduce the adverse effects of light and dark on the eyes.
5. The orientation and brightness of the chandelier: most of the lamps in the rooms where we generally live are hung on the ceiling, and the lighting required for daily life can be 40 watt fluorescent lamps or 60 watt bulbs.
6. The bulb should be updated in time: the lamp and the lamp in the room should be kept clean frequently, and the bulb must be replaced in time when the bulb is used for too long, or when the light shines or the lighting is reduced, it must be replaced in time to ensure sufficient illumination.

Study lighting pay attention to the local lighting effect of the light, with the writing desk lamp as the main lamp, under the premise of considering its brightness, but also pay attention to its appearance, its shape, color to be elegant and beautiful, suitable for the study of calm and elegant learning environment. Studies have shown that when the illumination of the surface of the object is 1000 lux, the human eye sees things most clearly and comfortably.
First, "no flicker" is the minimum condition for fluorescent eye protection lights. Fluorescent eye protection lamps on the market** generally come with a flicker test top. Rotate the top under the light of the eye protection lamp, and the edge of the top presents a clear and stable pattern; Under the light of non-eye protection lamps, the gyroscopic rotation will show a colorful or inverted hallucinatory pattern. >>>More
