SPECIFICATIONS

Housing:

6063 T5 extruded aluminum.

Optical system:

Constructed of highly specular aluminum, and a highly reflective 24 ga. metal, to produce a semi-indirect distribution.

Row ends:

Mitered aluminum extrusion sculptured end caps.

Joints & Intersections:

All joints shall be accomplished using TwinLock ™ 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 adjustable 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.

Approvals:

Certified to UL & CSA standards.

Finish:

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

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