Abstract: A light fixture or troffer for directing light emitted from a light source toward an area to be illuminated, including a reflector assembly within which the light source is positioned; a housing defining at least one selectively enclosable ballast enclosure; and a ballast that is positionable in the at least one ballast enclosure.

Abstract: A light fixture or troffer for directing light emitted from a light source toward an area to be illuminated, including a reflector assembly within which the light source is positioned and a lens assembly detachably secured to a portion of the reflector assembly such that a lens of the lens assembly overlies the light source and such that substantially all of the light emitted from the light source passes through the lens assembly. In one example, the lens includes a curved prismatic surface that can be oriented toward or away from the underlying light source.

Abstract: Functional yet decorative luminaires intended to create distinctive environments within specific areas of a space in which one or more luminaires are used, the luminaires of the invention visually tie to architectural elements of the space by providing a customizable glow of color surrounding a typically white light that acts to illuminate the space functionally. A downlighting luminaire configured according to the invention as one example is typically configured to utilize two separate reflectors, usually reflectors having concave reflective surfaces and being mounted concentrically within a housing, an inner reflector directing light centrally through an aperture of the luminaire with the light so directed typically being white light useful for illumination intended to facilitate usual activities within the space.
