What is Illuminance (Illumination)?
In photometry, illuminance is the measure of how much luminous flux (light) is spread over a given area. Essentially, it tells us how brightly a surface will be illuminated and how it will appear to the human eye. The standard International System (SI) unit for illuminance is the Lux (lx).
This converter is highly useful for architects, interior designers, photographers, and lighting engineers to ensure spaces meet standard lighting requirements.
