Choose white light or warm light for the bulb. Nowadays, the most important thing in people's lives is light. The brightness or darkness of light has a very important influence on the atmosphere of their lives, so the choice becomes particularly important. Choose white light or warm light for the following bulbs.
Choose white light or warm light 1. If white light is good for eyes in the workplace, it is better to use warm light in your bedroom. Warm light is closer to sunlight, with better color rendering, and white light is colder.
The choice of lamps depends on the color temperature value:
Simply put, the reading color temperature of 4000K (light yellow and soft white) is the best, and the reading lamp with 4000K color temperature is the best for eyes;
2700K second (incandescent lamps and halogen lamps generally have this color temperature, and the color rendering is better); At this color temperature, you need higher brightness to see things clearly. Note that many people say that you can't see clearly because of insufficient brightness or uneven illumination; 6500K is cold and white, which looks brighter, but it is easy for eyes to get tired after a long time.
Six criteria for selecting lamps:
1, no strongpoint with AC-to-DC design;
2. Warm yellow with a color temperature below 4000k;
3. The color rendering is at least above 90;
4. Obtained 3C certification and EU EN6247 1 Photobiosafety certification;
5, the irradiation area is large enough, uniform enough, and there is no obvious difference between light and shade;
6. Reflect glare as little as possible.
How to choose white light or warm light for light bulbs?
First, consider the overall atmosphere. We generally call the light that emits white light after startup white light, and the light that emits yellowish dim light after startup warm light. In daily life, warm light is more suitable for creating a warm atmosphere, because the light it emits is softer and slightly dim, so it is more romantic. If you want to build a small life for two people, then choose this one. If you choose white light, you will feel particularly bright and have no romantic feeling.
Second, considering the brightness, the light emitted by white light is brighter. If you want to read a book or do some meticulous work, you need to use this light. The light of the warm lamp is yellow, which is not suitable for reading at night or during the day. If used for a long time, it will cause very serious damage to the eyes.
Third, considering the decoration style, each decoration style is not exactly the same. If you choose modern style decoration or overall decoration to take a simple route, then you should consider white light more when choosing lamps. If you choose a more complicated European decoration, then you can consider choosing warm-colored lights. In addition, if the overall area of the new home is relatively small, try not to use warm lights, otherwise it will give people a feeling of depression.
Fourthly, considering the different functions in different regions, this selection method is actually the most commonly used method when choosing lamps in modern decoration. First determine which areas of the home need lighting, and then determine what effect the lighting in each area needs to achieve. For example, everyone will have a restaurant at home. If you choose lighting for the restaurant, you must choose warm lighting. First, when you want to create an atmosphere, the lighting is romantic enough. Secondly, things illuminated by warm lights will look more appetizing, so restaurants generally need to put warm lights; The study is not like this. The study is a place where people study and work. If you choose warm light, it will hurt your eyes, so you should choose bright white light after all.
Generally speaking, when the home is decorated, warm lights will be installed in bedrooms, restaurants and the like; White lights will be installed in places like living rooms and study rooms. hope

1, yellow light
Warm light is yellow light. For people who use desk lamps for a long time, yellow light will save more energy than white light. Therefore, yellow light is generally an energy-saving lamp, with small radiation, which reduces the cost of electricity. In fact, for most people, white light or yellow light is mainly used in space, and yellow light is preferred in bedrooms and living rooms because it is warmer and more emotional.
2. White light
Many people are struggling whether it is white light or yellow light when buying a desk lamp, but most people are more comfortable with white light. In fact, reading in white light is more eye-protecting. As long as the illuminance is adaptable, not too short and not too high, it can be within the acceptable range of human eyes. Therefore, it is not yellow light that must protect the eyes.
3. White light eye protection or warm light eye protection
The color temperature also determines the eye protection ability of the desk lamp, so whether it is yellow light or white light, as long as the light is stable and the color temperature is within the range, the eyes can look comfortable.

Second, use white light or warm light for homework.
Relatively speaking, it is better to use warm light when doing homework, because the light of warm light is yellow, the spectral distribution is the same, and the brightness is relatively stable, so it is suitable for doing homework. When choosing a light source, as long as the brightness is appropriate, it will not cause desktop reflection, and too bright light will also cause visual fatigue. It is also easy to stab the eyes.
