luminous intensity
Candela measures this
Luminous intensity measures the brightness of a light source in a specific direction, quantifying how much visible light it emits per unit of solid angle.
It's one of the seven base units in the International System, measured in candelas.
A standard candle produces roughly one candela of luminous intensity—hence the unit's name.
