The AD RO9 DI series is a direct/indirect version of the family of 9" round extruded aluminum luminaires. The series is furnished with a round clear ribbed acrylic lens to provide widespread indirect distribution. A round clear linear acrylic lens or a round radial baffle provides control of down light. The series can be suspended, wall mounted and mounted from wall to wall. These AD RO9 DI can be mounted individually, in perfectly aligned continuous rows, or in any combination of patterns. The AD RO 9 DI provide excellent direct control while softening the overall design effect with the indirect component.
