The Darth Vader lightsaber flashlight is equipped with 4 LED lights and has various authentic sound effects.
I guess that’s all a lightsaber can do in the hands of mere mortals. I’m also wondering if the red light is any good for illumination, or for adding a sense of dread on dark nights. This is a Sith Lord’s lightsaber after all.
You can buy the Darth Vader lightsaber flashlight at the Star Wars shop for only $25 (USD). 3 AAA batteries included. Because, you know, we can’t control the Force.
