Properties
$$M/T^3 \cdot U$$
$$kg/s^3$$
"Radiance" is a radiometric measure that describes the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle in a specified direction.
$$L = \frac{dI}{dA}\frac{1}{cos\alpha}$$, where $$dI$$ is the radiant intensity emitted from an element of the surface area $$dA$$, and angle $$\alpha$$ is the angle between the normal to the surface and the given direction.
