Both words describe light, the brightness that lets us see, but they stress different aspects of it.
Which one should you use?
lūx is a feminine noun that refers to the abstract concept of light or the source of light itself. In contrast, lūmen is a neuter noun used to describe the light that is emitted or the physical manifestation of light, such as light that is perceived by the eye or can be measured.
