    • A lighting system and device for providing indirect light using free-cavity, double-diffusing configurations are disclosed. In accordance with the embodiments of the invention, a lighting fixture comprises a cover structure with a diffusion layer and a reflective plate that form the free-cavity. The free-cavity is preferably configured to provide an output of light from a light source positioned within the free-cavity with an efficiency rating of 70% or more and provide better than an 8:1 ceiling lighting contrast between the rows of fixtures with rows on 16 feet spacing. Further, in accordance with a preferred embodiment of the invention, a device is configured to couple to a ceiling structure and provide the indirect lighting from a fluorescent light source.

    • A lighting device is disclosed that includes one or more master circuit boards configured to power light emitting diodes. The lighting device also includes modular light boards with arrays of light emitting diodes that interchangeably couple to the matched connectors on the master circuit board. The master circuit boards and the modular light boards are positioned within a housing with one or more diffuser lenses. In accordance with the embodiments of the invention, master circuit boards and modular light boards are mounted in a stacked arrangement to emit light from opposed sides of the housing. In further embodiments of the invention, the lighting device includes a controller for independently controlling light output from each master circuit board.
