If you have a bigger lighting budget than me then you should hop over to Pete's Etsy store and pick one up. The listing currently says there's three available so don't dawdle.
"As an added bonus, the two swords easily lift out of the lamp to be used in non-swordy, or pretend-swordy ways. Beware, the acrylic point is sharp, and could easily poke a hole in a priceless piece of artwork. Oh and also your brain. You don't want holes there."
This is a much better proposition that this energy sword I found on Ebay, where the seller is optimistically asking for $300.
