ABSTRACT:
A fluorescent lantern supports a pair of fluorescent tubes for vertical sliding movement so that the tubes can be replaced simply by removing the cover of the lantern and withdrawing the tubes. Each of the fluorescent tubes is supported in a socket in the base of the lantern and extends upwardly through an opening in the top of the lantern. The cover is removably attached to the top by tabs so that the cover can be removed by rotating and lifting the cover. When the cover is removed, the fluorescent tubes can be withdrawn upwardly through the openings in the top. The base includes a battery compartment for a battery power source, and the battery compartment is closed by a battery cover which is removably attached to the base by tabs so that the cover can be removed by rotating and withdrawing the cover.
