I learned about the arc lamp when I was a kid, watching Connections on PBS. John Burke explains it in one episode, and it appears during the title sequence of every episode. IIRC, it was invented to replace theater stage lights, where previously were lit by oil lamps, that had a tendency to start the set on fire.
