Turbolasers, shields and 200 gigaton figure

[Darth Wong]

OK, let's look at that. Assume a system has a radiator which can emit energy at a max rate of 7E22 watts: does this mean that it can do so even when the system has just been turned on? A blackbody radiator emits energy at a rate which is proportional to a function of its temperature, which is in turn a function of its internal energy. Does this system have something analogous to internal energy? Temperature? If it is an active radiator which doesn't work that way, what is the efficiency with which energy from other parts of the system are transferred to the radiator? Is it possible that component overheating from other parts of the system could cause system failure even if the actual radiation rate at the time is at or below 7E22 watts? Is it possible that it can only radiate 7E22 watts when the system is under full load, and that its actual radiative capacity is lower under other conditions?

See what I mean? Things can get complicated very quickly.
