Well, if it's just for classroom use, I used a film-strip projector
with a "fake slide" made out of thin metal, with a hole cut in it that
lit just the speaker and a bit of the podium. The film-strip projector
acts as an ellipsoidal light, but less intense (and very cheap).
This would not be suitable for a video you plan to distribute.
