This is the final version of 'Jedi Corridor Test' with post work done on the lightsabre. The green glow is a bit noisy but I'm happy with it. Any more samples and it would have taken too long to render.
I think the sabre looks all right, if you think about it bright lights usually look very flat so it's ok. I've checked many sabres images and decided that flat white with coloured halo is just how they're supposed to look, given their nature .
