expense of accuracy.

Radiant power spectrum from electroluminence spectrum

I am having a bit of a problem understanding a paper. Usually the authors use the electroluminescent spectrum to describe an emitter, but in this paper the radiant power is constantly cited.
What is the relation of these two?
