SPECIFICATIONS
Housing:
6063 T5 extruded aluminum.
Optical system:
Optical system constructed of highly specular aluminum
to produce a direct/indirect distribution. Aluminum parabolic louver shall have 16 cells
per 4 ft to produce 55 degree cutoff in all zones.
Row ends:
Mitered aluminum extrusion end caps.
Joints & Intersections:
All joints shall be accomplished using
QuickLock™ joining system. Optional intersections in "L",
"T", or "x" configurations, 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 certical 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.
