If I integrate all the power (radiation, matter particles, neutrinos) radiated from the cosmological horizon into the universe, what number do I get?

Is it true that the integral power/luminosity is of the order of $c^5/G = 3.6 \cdot 10^{52}$ Watt?

Has the integral horizon power been constant over the past evolution of the universe?
