We construct the effective Lagrangian describing the light glueballs associated with the unbroken and confining SUc(2) color subproup for the 2 flavor superconductive phase of QCD. This Lagrangian constitutes a key ingredient for understanding the nonperturbative physics of 2 flavor color superconductivity. We estimate the two photon decay process of the light glueballs using the saturation of the electromagnetic trace anomaly at the effective Lagrangian level. The present results are particularly relevant to our model of Gamma Ray Bursts based on color superconductivity in Quark Stars (R. Ouyed and E Sannino, astro-ph/0103022).
