We present semi analytical as well as numerical results (WENO) for photonic transport and Anderson localization of photons in laser active disordered ensembles of the hybrid perovskite CH3 NH3PbBr3 (MAPB) capped by PMMA. We compare experiments of two dimensional and three dimensional transport to time and space resolved numerics coherent to descriminate between directed random laser emission and exciton-polariton supported random laser emission. We present a systematic study of for disordered and quasi ordered ensembles.
