Morphology
The phrase 'brightness level' is a straightforward noun-noun measurement construction: 'brightness' (amount of light) combined with 'level' (degree or amount) yields the degree of brightness. This composition follows regular English compounding and is cross-linguistically common, so a B1 learner who knows the constituents will readily infer the meaning.
Etymology
Brightness level joins brightness (how much light something gives or reflects) and level (a point on a scale). Think of a dimmer switch moving up or down to make a lamp brighter or darker; that picture explains why it means 'how bright something is'.
