Scaling of single photon production in pp and collisions is studied. It is empirically observed that the available data scales for and for larger xT. The NLO pQCD predictions for pp collisions at an s1/2 of 200 and 5500 GeV, relevant for RHIC and LHC energies are seen to closely follow this scaling behavior. Implications for single photon production in heavy ion collisions are discussed.
