Remember that Star Wars Lightsaber Mini LED Flashlight from a while back? That was neat, but this Star Wars Lightsaber Flashlight is much cooler.
Not only is it incredibly detailed, but this flashlight is very practical as well. They come in Darth Vader and Anakin Skywalker versions and measure 1.5 inches in diameter by 10 inches tall. So yes, this is a nice solid flashlight, complete with sound effects when you turn it on and off.
It uses a trio of AAA batteries as a power source, unlike a real lightsaber which uses a crystal. This one is priced affordably at only $25.95 from Neatoshop.
UPDATE May 2012: The Lightsaber Flashlights are also available at ThinkGeek for $19.99.
