Abstract：The theory and method of measuring total radiant flux and total spectral radiant flux is described. The components and character of a goniospectroradiometer had been introduced. Three kind of light sources have been measured, the measurement uncertainty is 1.6%~3.6%(k=2). Luminous flux calculated by the spectra radiant flux comparison with NIM′s photometric based luminous flux scale shows that agreement is within 0.9%, well within the combined measurement uncertainty.
