NEO-RAY
DESCRIPTION
A graceful arched housing with elegantly contoured perforated lamp
diffusers and louver. Available in (2'x2') or (2'x4') configurations, these
luminaires have no visible lamps, fasteners, hardware, or glaring reflectors,
just soft, diffused, and comfortable lighting. "The Fenestra" 232/234/R Series
provide for a high-tech appearance. Combined, these elements make the
Neo-Ray Fenestra Series 232/234/R an appropriate luminaire for executive
offices, private offices, conference rooms, corridors, open office spaces, VDT
workspaces, reception areas and dining spaces. The isolated downlight,
along with dual switching, provides an ideal solution for areas requiring
reduction in vertical lighting for AV presentations.
