Construction: Two piece housing is die-formed 
cold rolled steel, forming an 8-5/8” x 1-3/4” 
architectural profile. Standard 4’-0” and 8’-0” fixture 
lengths combine for individual or continuous runs.
End Caps: End caps are precision die-cast 
aluminum, mechanically attached with no exposed 
fasteners.
Reflectors: Optical reflectors are die-formed high 
reflectance white painted steel. 
Electrical: Fixtures use UL listed Class P, T5 
program rapid start electronic ballasts. Power factor 
of 97% with less than 10% THD. Fixtures and 
electrical components certified to UL and CUL 
standards.      
Finish: Low-gloss white powder coated acrylic 
finish.
Mounting: Standard modular mounting includes 
hardware that integrates and suspends luminaire
