photobiological fluence rate
spherical irradiance spectrally weighted with a stated photobiological action spectrum
Note 1 to entry: This definition is based on the assumption that an action spectrum is adopted for the photobiological effect considered, and that its maximum value is 1.
Note 2 to entry: It is essential to specify which action spectrum is used, as the unit is the same for any action spectrum.
Note 3 to entry: The photobiological fluence rate is expressed in watt per square metre (W⋅m−2).
Note 4 to entry: This entry was numbered 17-884 in CIE S 017:2011.
