Lux: What is it and why is it important?

Mastering the various technical concepts in the lighting area is essential for understanding what you need to develop adequate lighting for your space. And Lux is undoubtedly one of the most frequent and important technical terminologies in our industry. Learn more about this concept in today's article.
The Lux (lx) is the unit of illuminance. Corresponds to the perpendicular incidence of 1 lumen on a surface of 1 square meter. 1 lux is equal to 1 lumen per square meter.
In lighting technology, it is used as a measure of the intensity of light that reflects or passes through a surface, as perceived by the human eye.
Luminance may vary depending on luminous intensity, surface area, light source aperture angle and surface reflection.
For example the same luminaire shining on two objects with the same surface area but different colors will have different illuminances. In this case, the lighter surface will have a higher illuminance value.
