The CRI color rendering index is one of the most important characteristics of a light source. It was introduced in 1965 in order to distinguish between light sources with the same color temperature because they conveyed colors differently.

CRI R9 is one of the color test patterns (TCS) used in calculating the extended CRI. However, many manufacturers list only the overall CRI, which does not include the CRI R9. Therefore, CRI R9 is often a useful additional indicator for evaluating a light source's color rendering ability, especially for objects whose reflectance spectra contain red wavelengths. A closer look at how R9 is calculated, along with the appropriate color test pattern (TCS9), is a general recommendation for anyone who needs to know about the color quality of a light source.

We see the transformation of light everywhere: in store windows, in the glare of the sun on water, and of course in the mirror. But we don't really think about the mechanisms and principles of this phenomenon. But these basics are actively used in different spheres of our life. Let's get to know what light is, how it refracts, and how it is used in life.
Irritability and headaches are consequences associated with high glare of the luminaire. Low glare and comfort is one of the basic requirements for modern residential and commercial lighting. In this article, we talk about the UGR characteristic and how to reduce glare.
What is light flicker? What effect does it have on human health? How to calculate the coefficient? In this article we have discussed the important characteristics of a light source in more detail.
Illumination is an important parameter for creating a comfortable workplace. It affects the productivity of labor, production performance and is directly related to human health. In this article we will try to understand in detail the main characteristics of the indicator, its types and regulated documents.

The color temperature is one of the main characteristics of LED products used for lighting. The question often arises, what is it and how to choose the right color temperature? Let's try to understand these questions.
This article is intended to answer questions about the degree of protection of the equipment against dust and moisture. Many people encounter the IP marking and wonder, - IP 65 what does it mean? Let's look at the standards used in Russia and show a detailed table of IP abbreviations.
Let's talk about the color rendering index (CRI or Ra): the impact on human health, a comparison of the performance of different products and a list of rooms where high CRI is important - a parameter that largely determines the comfort of working under artificial light.
Japanese experts from HOKASU have developed a completely new product - LED module. The product is superior in reliability to any powerful LED strip. In this article we will consider the advantages of the modern light source and its difference from the tape.
An important component of a linear luminaire is a diffuser. It performs a number of functions: from "leveling" the light flux to mechanical protection against dust and moisture. Let's try to analyze the types, technologies and design features in more detail.
In addition to providing eye contact, lighting affects the physical and psychological state of the person. Let's study this issue and calculate the "right" illumination!
