This suspended nominal 4'- or 8'-long LED luminaire is constructed of extruded aluminum with die-cast aluminum end-caps and no exposed fasteners. Using edge-lit guide technology, its LEDs deliver up to 4,400 nominal lumens per 4' section in 3000K, 3500K, and 4000K at a CRI of 80-plus. Its optical system uses a high-performance acrylic lens with a microstructure film. An integral electronic zero-to-10V dimming driver accepts 120V, 277V, or 347V. Fixtures can be joined together with internal joiners to rows. Optional embedded controls allow for lumen management and networking via a CAT-5e cable and remote power pack. Housing and end-cap is finished in a choice of low-gloss white, black, or painted aluminum. CSA and CUS listed.
