The problem of black-body radiation is considered in the Born-Infeld theory
of electrodynamics. In particular, at 2-loop order the deviation from the
Planck expression due to the self-interaction of photons is calculated. It is
seen that the system of interacting photons of the theory, opposed to its
non-Abelian counterpart, has higher internal energy at this order of
perturbation. Possible implications of the result on the evolution of very
hight temperature systems, including various stellar media and the early
universe, are briefly discussed.
