We report, for the first time to our knowledge, comparisons of light scattering computations for large, randomly oriented, moderately absorbing spheroids based on the geometrical optics approximation and the exact T-matrix method. We show that in most cases the geometrical optics approximation is (much) more accurate for spheroids than for surface-equivalent spheres and can be used in phase function computations (but not in polarization computations) for nonspherical particles with size parameters as small as 60. Differences in the single scattering albedo between geometrical optics and T-matrix results are surprisingly small, even for small size parameters.
