In a pure DF vs. DF battle, it is impossible to tell. Neither of them are physical matter, to my limited physics knowledge, so neither of them can hurt one another. Someone said "they are both fast" but light is still faster. Honestly, I think the light person might be able to bypass the lightning person's reflexes and simply shoot a laser through their head. Speed is everything.
