About this product
Medius is Lumenwerx's compact architectural linear family, packing high-performance optics into a slim 1 15/16" x 4 3/4" extruded-aluminum profile. It is offered in direct and direct/indirect distributions, pendant-mounted on fixed or sliding aircraft cable or stem, or wall-mounted, and configures as individual luminaires or virtually seamless continuous runs from 4 ft standard sections (4, 8, and 12 ft) joined onsite. A five-optic direct menu tailors the beam: Miniature Reflector Optics (MRO) in narrow 18-degree, medium 35-degree, and wide 55-degree spreads with individual TIR elements over each emitter; Specular (SPL) and Matte Silver (MPL) parabolic louvers with 1-inch blades shielding 50 degrees lengthwise and 45 degrees crosswise for ANSI/IES RP1-12 VDT compliance; and the High-Efficiency Lambertian Optic (HLO) diffuser. Direct/indirect versions pair HLO downlight with the Widespread Asymmetric Indirect Optic (WAI2) uplight. Delivered output spans 350, 500, 750, and 1000 lm/ft on the direct side (350 to 750 lm/ft indirect), with visual comfort at UGR better than 16 and efficacy up to 134 LPW. Medius ships with 80 CRI static white (90 CRI with elevated R9 optional, 3 SDCM) in 2700/3000/3500/4000K, or ChromaWerx tunable white (separate spec), dimmable 100 to 1 percent via 0-10V standard with DALI and Lutron Hi-lume 1% Eco driver options on universal 120-277V input (347V available). LEDs are LM-80 tested to L80 greater than 60,000 hours. ETL listed to UL 1598 and CSA C22.2 No. 250.0 for indoor dry/damp locations, backed by a five-year limited warranty.
