Introducing the DIA, a low profile recessed luminaire that provides a uniform soft illumination to enhance office and public spaces both with its aesthetics and high efficiency. Paired with our unique highly transparent VL Optic diffuser, the DIA achieves enhanced lighting performance (85 percent efficiency), while still providing a pleasant evenly lit environment. The VL Optic acts as a virtual louver by redirecting the light rays uniformly at high angles while eliminating unsightly glare, highlighting the architectural details of the surroundings without harsh shadows. The DIAs slender curved optics complement modern interior designs. Other design features, such as a hinged center optic component and ballast covers, contribute to easy and time-saving maintenance.
