In a scientific context, it can denote the basic unit of light intensity or the smallest discrete packet of electromagnetic radiation, which is a photon. The concept of a valoyksikkö is crucial in fields such as physics, optics, and photometry.

When discussing measurement, a valoyksikkö might refer to a standard unit used to quantify light, like the candela, which measures luminous intensity. Alternatively, it can signify a specific device designed to emit or detect light, such as a light bulb or a photodiode, when these are considered in their most basic functional role as a unit of light. The precise meaning of valoyksikkö often depends on the specific domain or context in which it is used. It encapsulates the idea of a single, definable entity or quantity pertaining to light.
