SPECIFICATIONS

Housing: Die-formed 24 ga. metal painted white

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

Joints: Integral with each module. One screw required per joint (provided by others) to attach to structure.

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.

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