Several measures of light are commonly known as intensity. These are obtained by dividing either a power or a luminous flux by a solid angle, a planar area, or a combination of the two Angular Radiant intensity, measured in watts per steradian (W/sr) Areal Irradiance, measured in watts per square meter (W/m2), called intensity in most branches of physics Both Radiance, commonly called intensity in astronomy and astrophysics (W·sr?1·m?2)
