NEO-RAY
DESCRIPTION
The Nimbus II series offers simple design and flexibility without sacrificing
performance. Multiple lamp configurations in T8 and T5 high output
fluorescent provide maximum flexibility for the architectural environment.
In addition, the Nimbus II is modular with suspension points falling on exact
48" increments for ease of installation. Nimbus II creates a comfortable and
uniformly balanced environment. All of these elements combined make the
Nimbus II an excellent selection for large open office areas, VDT
workspaces, classrooms and virtually any open space.
