Abstract: A relocatable add-on control sensor module is described which electrically connects and controls at least one recessed light fixture. The add-on control sensor module includes a sensor ethernet socket that may be electrically connected by an ethernet cable to a light fixture ethernet socket of the at least one recessed light fixture so that the add-on control sensor module may control the at least one recessed light fixture.

Abstract: A fluorescent luminaire has a luminaire housing, a lens frame positioned within the luminaire housing, the lens frame having a first side frame member and a second side frame member connected to a first end frame member and a second end frame member, a flexible plastic lens having a length, wherein a distance between the first and second side frames is less than the length of the plastic lens and, wherein the lens curves from the flat orientation to a curved orientation when seated between the first and second side frames corresponding to curvature of the first and second end frames.

Abstract: A relocate able add-on control sensor module is described which electrically connects and controls at least one recessed light fixture. The relocate able add-on control module is mounted to a suspended ceiling t-bar grid and can be positioned anywhere in the ceiling grid while still controlling one or more recessed lighting fixtures. The control sensor module containing at least one sensor controlling light output of at least one recessed lighting fixture based on human occupancy, light intensity or both.

Abstract: A fluorescent lighting fixture is provided with an assembly housing on the top thereof formed of sidewalls and a removable cover and endcaps. When the cover and endcaps are removed, sequential end-on-end placement of a plurality of the fluorescent lighting fixtures causes a channel to be formed into which a continuous common electrical power line is placed. Each ballast assembly communicates with the electrical power line.

Abstract: The apparatus is a nestable fluorescent fixture housing of a truncated pyramid shape with "knock-out" apertures provided on the sloping walls thereof to engage the ends of fluorescent bulbs. A wedge-shaped separate ballast/socket assembly is provided for each fluorescent bulb, preferably a "biax" bulb. The slope of the wedge shape of the ballast/socket assembly is complementary to the slope of the walls of the fixture.
