Master Replicas brings you the only licensed recreation of Darth Vader lightsaber, fully authorized and endorsed by Lucasfilm. Recreated from original Lucasfilm archival materials, this replica is superb in its accuracy to the lightsaber seen in Star Wars: 

Constructed from durable die cast metal components, this FX lightsaber also features a permanently attached polypropylene blade which encases and electro-luminescent (EL) core. Integrated sensor switches control the pitch and playback of the lightsaber sounds, including an impact sound when the blade encounters an obstacle. Features 8 motion sensor controlled sound effects: power-up, power-down, idle, movement (4 sounds) and clash. Once activated the blade glows brightly and the replica plays back digitally recorded sound effects taken directly from the film. Approximate dimensions of the Lightsaber: 44” L x 2” H x 2” W

This is in used condition and therefore has wear marks and scuffs on the bladeand blade doesnt light all the way through. No box or stand is included, just the blade.
