Assuming a "steady state" flow means that the time for the power to course through the lightbulb is negligible, right? In other words, we don't care about the "wind-up" (or power up sequence) that occurs for the light bulb to begin shining

Re: what Brandon said above, I believe that's correct. The energy consumption rate being constant would seem to imply that the real "wind-up" in lightbulbs (fluorescent especially) isn't represented in the graphical space, which technically makes sense.

I think this slide is another example of how much computer graphics is about modeling reality, and how it is an engineering problem. Algorithmic complexity and overall speed of running code is extremely important since many rendering tasks are of high detail and happen in real time. Going off what snowshoes7 said, it is possible that the vast majority of implementations of rays cast from light bulbs don't account for "wind-up" partly because it adds complexity and usually has no benefits to many rendering tasks. Thus, the model of "steady state" is good enough (even though it's not exactly how many real lights work).
