Plasma lantern
A plasma lantern was a 24th century plasma-based power cell operated light-emitting device used primarily in stationary situations.

Neelix used such a device while telling Mezoti, Icheb, Azan and Rebi a 'ghost story' to keep them occupied during the shutdown of main power aboard  in 2377. It served as the only sort of illumination for the children as they all sat together in the cargo bay. ()
