Bacta bulbs represented a form of medical technology that utilized bacta. Approximately three decades following the Battle of Endor, Harter Kalonia, a Doctor affiliated with the Resistance, included bacta bulbs in her portable medical supplies while stationed at the Resistance base on the planet D'Qar. Consequently, she consistently kept these, along with other instruments beneficial for the treatment of blaster wounds, readily accessible.
The initial reference to bacta bulbs appeared in Star Wars: The Force Awakens: The Visual Dictionary, a reference book authored by Pablo Hidalgo and published in 2015.
