Formulas:
Planck constant h = 6.62606957*10-34 J*s
Speed of light c = 299792458 m/s
c = λ*f
Elektron-volt: 1 eV = 1.602176565*10-19 J
E = h*c / λ
Ep = E / (1.602176565*10-19)
T at λmax = 2,89776829 nm * Kelvin / λ (Wien's displacement law)
T at λmax is the temperature of a black body, whose radiation has a maximum at λ.
Photons per joule = 1 / (1.602176565*10-19 * Ep)
