We study radiative decays of D{sub sJ}*(2317) and D{sub sJ}(2460) using light-cone QCD sum rules. In particular, we consider the decay modes D{sub sJ}*(2317){yields}D{sub s}*{gamma} and D{sub sJ}(2460){yields}D{sub s}{sup (}*{sup )}{gamma},D{sub sJ}*(2317){gamma} and evaluate the hadronic parameters in the transition amplitudes analyzing correlation functions of scalar, pseudoscalar, vector, and axial-vector cs currents. In the case of D{sub sJ}*(2317){yields}D{sub s}*{gamma} we also consider determinations based on two different correlation functions in heavy quark effective theory (HQET), in order to estimate the finite charm-quark mass effects. The mode D{sub sJ}(2460){yields}D{sub s}{gamma} turns out to have the largest decay rate among the radiative D{sub sJ}(2460) channels, as experimentally observed, a result thus favoring the interpretation of D{sub sJ} states as ordinary cs mesons.
