Construction: Housing is one-piece, die-formed, 
cold rolled steel, forming a 10-3/4” x 2-1/2” curved 
architectural profile. Perforated sections are 33% 
open with staggered hole pattern and opal diffuser. 
Standard 4’-0”, 8’-0” and 12’-0” luminaire lengths 
combine for continuous runs.
End Caps: End caps are precision die-cast 
aluminum mechanically attached without exposed 
fasteners.
Reflectors: Center reflector is die-formed, highly 
specular aluminum.
Electrical: Luminaires are prewired with quick wire 
connectors and use UL list Class P, T5HO or T8 
program rapid start universal voltage electronic 
ballasts. Power factor of 97% with less than 10% 
THD. Fixtures and electrical components certified to 
UL and CUL standards.   
Finish: Luminaire housings are standard white 
using electrostatically applied acrylic powder coat 
paint.
Mounting: Standard mounting includes dual 
aircraft cable and mounts directly to all ceiling 
types. Row mounted fixtures are continuous with 
hairline joints unless Articulated Joint option is 
specified. Mounts on fixtures with Articulated Joint 
option will not align with grids.
= Slim Line Ballast only.
