LightSabers are a technology that utilizes specially generated special effects and actors to produce laser like sword effect for movies. LightSabers were invented by George Lucas and have not been licensed to any other movie franchise.
The surface of a LightSaber is glowing with light that changes color when it is near someone with the force. The cuts from them last forever. Currently LightSabers are only avbailable in three colours, red, green and the rarely seen purple.
Recently, eipisode 3 of Star Wars introduced a purple LightSaber.
The list of manufacturers of LightSabers is non-existant.
I hate fake posts that pretend their advertising is news...
