SPECIFICATIONS

Housing: 6063 T5 extruded aluminum.

Optical system: Optical system constructed of highly specular aluminum, and highly reflective 24 ga. metal, to produce an indirect distribution.

Row ends: Mitered aluminum extrusion end caps.

Joints & Intersections: All joints shall be accomplished using QuickLock TM joining system. Optional intersections in "L", "T", or "X" configu-rations, shall be mitered aluminum extrusion.

Mounting: Brackets attach to existing structure anywhere behind fixture. Fully adjust-able mounting brackets to provide up to 1/8" wall variance and allow for vertical fixture leveling.

Electrical: All luminaire sections shall be factory pre-wired to section ends. Optional quick connect plugs are available.

Ballast: Electronic: rapid start, instant start or dimming.

Approvals: Certified to UL & CSA standards.

Finish: Thermosetting polyester, electrostati-cally applied meeting AAMA 603.8. Available in Ledalite standard white and in a full architectural spectrum of colors. Medium gloss finish as standard.

*Asymmetric effectiveness refers to the percentage of lamp lumens distributed on the room side of the luminaire, above 90 degrees.
