Based on a floor reflectance of 0.2

Housing:

6063 T5 extruded aluminum.

Optical system:

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

Row ends:

1/4" aluminum end plate or mitered aluminum extrusion end caps.

Joints & Intersections:

All joints shall be accomplished using QuickLock joining system. Optional connectors in "L", "T", or "X" configurations, 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, instant start or dimming.

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