Hey, I don't come up with this stuff. I just flip through the tech references and RPG books. And all of them give exactly the same description of lightsaber technology.

Note that, as was said elsewhere, while lightsabers certainly glow, that glow fails to give off any real illumination. Most LEDs are like this; while they can glow quite visibly, even in bright sunlight, they're not particularly good at providing illumination. I've got a Swiss Army knife with an LED emergency light in it, and the only thing that the emergency light is good for is finding your real flashlight, and that's assuming you have a pretty good idea where it is relative to you to begin with.

Either way, most SW tech is extremely exotic, and is meant to verge onto that whole Arthur C. Clarke thing about sufficiently advanced technology. The tech base in SW is at least twenty-five thousand years old, after all.
