‌ The manifestation of a lamp is the Color Rendering index (Ra) ‌

• ‌ definition ‌ : Color rendering index (Ra) is a common parameter in the field of lighting technology, referring to the ability of a light source to restore the color of an object. It is determined by comparing the appearance color of an object with a reference or reference light source (such as an incandescent lamp) of the same color temperature ‌.
• ‌ range ‌ : The color rendering index ranges from 0 to 100, the higher the value, the stronger the ability of the light source to restore the object color ‌.
• ‌ benchmark ‌ : The color rendering index of the sun is defined as 100, and the color rendering index of the incandescent lamp is very close to the sunlight, so it is regarded as the ideal benchmark light source. The display finger of LED is usually between 60-90, and the display finger of sodium lamp is lower ‌.
• ‌ application ‌ : color rendering index is an important parameter to measure the color characteristics of artificial light source, for places requiring high color reproduction, such as art galleries, studios, etc., should choose the light source with higher color rendering index ‌.

Color rendering index: Is higher better?

• Color rendering index definition ‌ : color rendering index (Ra) is a measure of the ability of the light source to restore the color of the object index, the value range is 1-100.
• ‌ color rendering index and color reproduction ‌ : The higher the Ra value, the stronger the color reduction ability of the light source, the smaller the difference between the color of the illuminated object and the "original color" of the object. The Ra of sunlight is 100, which is the ideal reference light source.
• ‌ The choice of color rendering index ‌ : in the selection of lamps, the closer the color rendering index is to 100, the better the color rendering, the more real the color reproduction. However, the color rendering index is not the only consideration, but also needs to consider the performance of the lamp, visual effects and comfort.
• For families with children, choosing an eye lamp with a high color rendering index can not only make the child's world more real, but also help the child's color vision development and cognition!
  In addition to the color rendering index, flash frequency and anti-blue/anti-glare are also the focus of attention when choosing eye protection lights! Choose no video flash eye protection light, can reduce eye fatigue and visual interference, improve visual comfort. At the same time, the anti-blue light and anti-glare function can also effectively protect the child's eye health.

How to choose a lamp with the right color rendering index?

• Learn about the color rendering index ‌ : The color rendering index (Ra) measures the ability of a light to reproduce the true color of an object on a scale of 1-100, with the higher the number, the more realistic the color is ‌.
• ‌ Select ‌ on demand: For main lighting or accent lighting, it is recommended to choose lamps with a high color rendering index (Ra≥90) to provide better color reproduction. Auxiliary lighting such as lamp belt, wall lamp, etc., color rendering index requirements can be appropriately reduced ‌.
• ‌ Consider the special color rendering index ‌ : in addition to the general color rendering index Ra, pay attention to the special color rendering index (such as R9), which affects the ability to restore specific colors such as red. For places that need to accurately restore colors, R9 should also be greater than a certain value (such as 70) ‌.
• ‌ combined with other factors ‌ : when choosing lamps, it is necessary to consider illuminance, color temperature and other factors to create a comfortable lighting environment.

Home lighting color index selection:

• Restaurant - Food in the high-display light irradiation, will appear more delicious and attractive, easy to stimulate the appetite.
• Kitchen - Under the high light, it is better to judge the freshness of vegetables, fruits and meat.
• Bathroom - need to wash and groom before going out, high display means that the light can better restore the true skin color of people.
• Cloakroom - High display lights give cloakrooms the same ability to reproduce clothing colors as shopping malls.
• Study - reading, reading and work are inseparable from the light, high display means that the light can better protect the eyes. If you choose a lamp with low display, the color reflected back to the children's eyes will lose saturation, resulting in color distortion, easy to cause visual fatigue, which may lead to myopia.
