Intended Use

The Surface Volumetric™ series is designed for surface or suspend-mount applications that require the appealing aesthetics and high performance of volumetric lighting. Ideal for offices, workrooms, retail and other commercial applications. Available in 2 or 3-lamp, T5 or T8 configurations, this series provides tremendous design flexibility. Certain airborne contaminants can diminish integrity of acrylic.


Housing is roll formed from code-gauge steel. Impact resistant 25% DR acrylic diffuser attaches to die cast ends by simple hook and pin design with controlled tension provided by sonically welded end plate, providing secure installation and easy maintenance. Decorative die-cast end caps provide added durability

Finish: All metal parts are post-painted in white polyester powder coat for smooth, finished edges and uniform light distribution. Natural aluminum finish available on end caps (see Options).

Injection-molded plastic light traps prevent light leaks between shielding and end plates and centers diffuser on channel.


Volumetric illumination is achieved by creating an optimal mix of light to vertical and horizontal work surfaces, rendering interior space, objects and occupants in a more balanced luminous environment. Crescent-shape linear faceted refractor provides uniform light distribution and high angle brightness control.
