Several measures of
light are commonly known as
intensity:
- Radiant intensity, a radiometric quantity measured in watts per steradian (W/sr)
- Luminous intensity, a photometric quantity measured in lumens per steradian (lm/sr), or candela (cd)
- Irradiance, a radiometric quantity, measured in watts per meter squared (W/m2)
- Radiance, commonly called "intensity" in astronomy and astrophysics (W·sr-1·m-2)
