An improved lensed fluorescent troffer lighting fixture intended for ceiling mounting and particularly for recessed mounting to a suspended ceiling grid within a shallow plenum, the embodiments of the fixture having dimensions, particularly depth-wise dimensions, which allow installation within the confines of reduced plenums while maintaining fixture quality and retaining desirable characteristics such as minimal lamp image. The present lensed troffers can be manufactured at a high assembly rate due to the ability to snap together on an assembly line the various components of the fixture without the use of separate fasteners. The lensed troffers of the invention are particularly configured for use with T8 fluorescent lamping and low profile electronic ballast. The configurations of the several embodiments of the present lensed troffer are chosen to fit within a shipping box shaped in a manner to allow maximum stacking efficiency and to maximize the number of fixtures which can be shipped within conventional volumes encountered in available transport vehicles.
