WebFeb 10, 2024 · To make a really crude estimate and avoid photometric vs radiometric units, the Sun provides a radiant flux of about 1400 W/m 2. If we assumed all of this was photons at 550 nm wavelength (definitely not true) and each photon (E = h*f/lambda) has an energy of 3.6 *10 -19 J, the photon flux would be 3.9*10 21 photons per second. WebII.7.f. Conversion between radiometric and photometric quantities Monochromatic radiation: In the case of monochromatic radiation at a certain wavelength λ, a radiometric quantity X e is simply transformed to its photometric counterpart X v by multiplication with the respective spectral luminous efficiency V(λ) and by the factor K m = 683 lm ... sae in research
