Selka is Lumenwerx's architectural linear pendant, distinguished by angular end caps, a deep interior channel, and a crisp aspect ratio. It is offered in direct and direct/indirect distributions, pairing a widespread indirect uplight with a soft, well-shielded downlight. Two downlight approaches are available: a regressed High-Efficiency Lambertian Optic (HLO) using matte-white reflectors across 0.075" acrylic shielding for up to 88% transmission, or regressed parabolic louvers — 1" deep blades regressed 1 3/16" into the housing with 50° lengthwise / 45° crosswise shielding — in matte black (MBPL), matte (MPL), or specular (SPL) finish. The indirect side uses the Widespread Indirect Optic (WIO2), a micro-prismatic array with a 160° spread for even ceiling brightness. Delivered output runs 350 to 1000 lm/ft with efficacy published up to 148 lm/W (WIO2). Direct packages are 500/750/1000 lm/ft and indirect packages 350/500/750/1000 lm/ft. The extruded-aluminum housing is built from standard 4 to 12 ft sections (1 ft increments, 4 ft minimum) joined on site with seamless joiner kits for continuous runs over 12 ft. Selka carries an 80 CRI static-white LED source (90 CRI with elevated R9 optional, 3 SDCM) in 2700/3000/3500/4000K, tested to LM-80 with L80 lumen maintenance greater than 60,000 hours. Standard dimming is 0–10V 100–1%, with Lutron Hi-lume 1% Eco, eldoLED 1% ECOdrive and 0.1% SOLOdrive, ELV, TRIAC, and DALI driver options on universal 120–277V input (347V with the standard driver); the platform is PoE compatible. Pendant mounting is by aircraft cable or stem, with multi-circuit and emergency/night-light/daylight/generator-transfer electrical sections and integral emergency battery options. ETL listed to UL 1598 and CSA C22.2 No. 250.0 for indoor dry/damp locations, backed by a five-year limited warranty.
