Luminara Unduli's lightsaber was a green colored lightsaber that belonged to Jedi Master Luminara Unduli throughout the Clone Wars. It shared design similarities with Plo Koon's lightsaber, featuring a radiator casing with fins and a gripping surface with ribs. The hilt showed signs of wear, reflecting the extensive time its owner spent on missions.
Throughout the Clone Wars, Master Unduli employed her lightsaber with the green blade on numerous battlefields, notably during the First and Second Battle of Geonosis, and in combat with the dark side force user Asajj Ventress. During the second Geonosis conflict, Luminara was surprised in an attack by resurrected Geonosian soldiers and taken prisoner, resulting in the loss of her lightsaber. Obi-Wan Kenobi found the weapon when he and a group came to look into Luminara's vanishing; Anakin Skywalker briefly used it with his own before it was given back to Luminara.
