Is white light better or warm light is better for the eyes?

If the white light in the office at the work place is good for the eyes, it is better to have a warm light in the bedroom at home. Warm light is closer to daylight, the color rendering is better, and white light is cooler.

The choice of light depends on the color temperature value:

Simply put, the color temperature of 4000K (slightly yellow, soft white) is the best for reading, and the reading light with 4000K color temperature is the best for the eyes;

2700K is second (incandescent lamps and halogen lamps generally have this color temperature, and the color rendering is better); higher brightness is required at this color temperature to see things clearly. Note that many people say that it is not because of insufficient brightness or uneven lighting; The 6500K is cool white and looks brighter, but the eyes get tired after a long time.

6 criteria for choosing a good lamp:

1. Use non-flicker-free lighting fixtures designed for direct transfer;

2. Warm yellow with color temperature below 4000k;

3. The color rendering is at least above 90;

4. Obtain 3C certification and EU EN62471 photobiological safety certification;

5. The irradiated area is large enough and uniform, and there is no obvious difference between light and dark;

6. Minimize the reflection of glare.
