| 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).
