How to Build a Cheap Lightsaber
A flashlight makes a great lightsaber handle. (flashlight image by Wayne Abraham from

The lightsaber is the ultimate intergalactic weapon. Every true Jedi or Sith uses one, and you can too. You'll need some basic materials, all of which can be found in your local hardware store. Constructing your lightsaber shouldn't cost more than £13, if you spend wisely. That's a small price to pay for access to the Force! Constructing your own cheap lightsaber helps you to further connect with your favourite "Star Wars" characters without spending a fortune.

  1. 1

    Install fresh batteries in a small flashlight. The flashlight acts as your lightsaber's handle and light source.

  2. 2

    Place the flashlight on a coloured slide transparency with the lens facing down. Trace the shape of the lens onto the transparency using a marker. Cut the transparency along the traced line. Attach the cutout to the flashlight lens using electrical tape.

  3. 3

    Obtain a cylindrical plastic tube to use as a lightsaber body. The tube should have roughly the same diameter as your flashlight lens. Finkbuilt recommends using plotter paper roll cores, which can be obtained from many print shops. Alternatively, a clear PVC pipe will work.

  4. 4

    Attach a piece of reflective material to the top end of your lightsaber body. Tinfoil works well for this purpose. Attach the tinfoil to the lightsaber using electrical tape.

  5. 5

    Slide your lightsaber body over the flashlight lens. Attach the body and handle using electrical tape. Alternatively, use duct tape for a metallic look and feel.

  6. 6

    Power up your lightsaber by pressing the flashlight's "on" button. May the Force be with you!

Tips and warnings

  • Use the brightest flashlight you can find to maximise your lightsaber's glow.
  • If you can't find a coloured slide transparency, use the lenses from a pair of 3-D glasses.
  • Don't cover the flashlight's power switch with tape. Doing so will prevent you from turning the lightsaber on or off.
