What is the SPD of a light source?

SPD is the Spectral Power Distribution of a light source. The visible white light that we see is made up of a spectrum of various colours of light ranging from wavelengths 380nm (violet) to 760nm (red). The SPD is a graph which shows the power (strength) of each wavelength of light produced by a particular light source.
