design statement

Style Type Mounting Length Lamps Color & Voltage

■1 Housing: Extruded aluminum. Die-cast end cap mechanically attached with no exposed fas- teners. Concealed access holes in end plate for through wiring.

■2 Lamping: One, two or three T8 fluorescent lamps, as specified. Provided by others.

■3 Reflector: Accurate parabolic-shaped, die-formed semi-specular anodized aluminum reflector.
