Sound, even very loud sound, doesn't contain much energy.
And, a 100W arc lamp is really, really bright.
So you can lose a not very large amount of energy in the gap, and it
will be pretty bright and loud.
If you've ever seen and heard a BIG jacobs ladder (like the one at the
Deutsches Museum) running many kilowatts, you'll get an appreciation of it.
