This motion-sensing, light-up saber makes swooshing and crashing sounds and comes in two colors - blue is the Anakin Episode III saber, and red is the Darth Vader Episode V saber. It has 64 ultra bright LEDs in a polycarbonate (the material used to make lenses in sunglasses, etc; really tough and lightweight) blade. The lights are serially-linked for a power-up and power-down light display. The hilt is metal and holds batteries.
