Via 4 is the largest-output aperture in Lumenwerx's Via flagship linear platform, offered in direct, indirect, and direct/indirect distributions across pendant (aircraft cable or stem), surface, recessed (drywall trim/trimless and grid ceiling), wall, and vertical mountings. The extruded-aluminum profile is configurable in 1 ft and 1 in increments from 2 ft sections to seamless continuous runs, with delivered output from 350 to 1500 lm/ft and efficacy published up to 146 lm/W. A nine-optic menu tailors the distribution: High-Efficiency Lambertian (HLO), Asymmetric Refractive (ARO2), Wall Wash Refractive (WRO2), Widespread Direct (WDO), Low-Glare (LGO), and Micro-Prismatic (MPO) on the direct side, plus Widespread (WIO2), Translucent (TIO), and Widespread Asymmetric (WAI2) indirect optics. Via 4 ships with 80+ CRI static white (90+ CRI with elevated R9 optional, 3 SDCM) in 2700/3000/3500/4000/5000K, or BIOS SkyBlue Static, Dynamic, and Tunable circadian solutions, dimmable 100–1% via 0–10V, with Lutron Hi-lume 1% EcoSystem, eldoLED, ELV, TRIAC, DALI, and PoE driver options. ETL listed to UL 1598 and CSA C22.2 No. 250.0 for indoor dry/damp locations, LBC Red List Declare approved, and backed by a five-year limited warranty.
