Lightsaber lamp eschews snideness
No date-repellant references, for once.
So we'll just pass along this item from Technabob about a "Lightsaber lamp" from Japan. We're not so sure how much light they give off, but they do come in Jedi and Sith models (green and red, respectively).
But be aware that these lamp-sabers measure less than 16 inches, so don't expect to have any impromptu.
