Duo is OCL Architectural Lighting's dual-direction linear suspended luminaire — a simple 3 in wide by 5.132 in high extruded profile with frosted white acrylic top and bottom lenses that emit light both up and down. The housing is extruded and welded aluminum with cast-aluminum end caps and a formed aluminum canopy; OCL's proprietary LED arrays use Nichia 757 diodes with 3-step color binning. It is offered in 24, 36, 48, 60 and 89 in lengths and can be joined end to end into continuous runs, with fully illuminated "L", "T" and "X" junctions available for special configurations. Delivered output (measured at 3500K, 80+ CRI) for the 2LED1 tier is 1,760/2,640/3,520/4,400/7,040 lm at 25/40/56/65/95 W across the five lengths, and for the 2LED2 tier is 2,650/3,900/5,290/6,550/9,700 lm at 42/62/84/104/154 W, at up to 70 lm/W (per the DO1-P1EB-24 LED1 photometric test, report no. 18334.0). Values scale by 0.95 for 2700K, 0.97 for 3000K and 1.03 for 4000K, and 90+ CRI output uses a 0.85 multiplier. Color temperatures are 2700K, 3000K, 3500K and 4000K in 80+ CRI (R9 > 0) or 90+ CRI (R9 > 50). The P1EB hanging system suspends the fixture on an aircraft cable at each end with a power cord on one end, mounting to a 4×4 in octagon or 4 in round junction box; field replacement of the LED arrays and drivers requires minimal effort. Fixtures run on universal 120–277V input with 0-10V dimming to 1% standard (DM1); an optional BIOS SkyBlue / SkyBlue Dynamic circadian engine is available. Finishes cover a full powder-coat palette (matte white, black, brass metallic, bronze, black/white textured, graphite, goldtastic, steel gray, silver metallic, sky white), a brushed-aluminum metal finish, and an Everwoods wood-grain collection on the body (white pine, pine, cherry, teak, walnut, dark walnut, light and dark barnwood), plus RAL, Pantone and custom. ETL listed to UL 1598 for indoor dry locations (optional damp label), Build America Buy America (BABA) compliant, and backed by a five-year limited warranty.
