SELKA
Direct, Direct/Indirect
With angular end caps, deep interior channel, and pleasing aspect ratio, Selka presents a crisp, refreshing style. Widespread uplight, comfortable downlight, high efficacy, and generous light output all make Selka eminently practical. Selka offers two distinctive downlight options: a regressed light guide and regressed parabolic louvers, in either specular or matte finish. Both options combine visual comfort with good cut off and a soft downlight distribution.
For direct/indirect distributions, our light guide optic produces smooth ceiling brightness and wide spacing. Selka can be installed as discrete luminaires or continuous runs. The compact profile accommodates all LumenWerx electrical options, including independent control of indirect and direct lighting.

OPTICS
Regressed Light Guide (RLG)
The Regressed Light Guide (RLG) consists of side-mounted LED arrays, coupled to an optical-grade acrylic light guide engraved with micro-structure optics that extract light into a lambertian distribution. An upper reflector of 98% reflective, diffuse aluminum enhances system efficiency. A thin diffuser below the light guide provides additional source obscuration.
The entire assembly is regressed 2" into the luminaire housing for deep lateral shielding. Angled side panels with a high-reflectance, matte white finish direct light into a soft and widespread downlight distribution, with spacing criteria of 1.4.
Parabolic Louvers (SPL and MPL)
Selka’s parabolic louvers provide excellent shielding and a pleasing crisp visual texture. The precisely molded louvers consist of 1" deep blades and side reflectors with shielding of 50° lengthwise and 45° cross wise
The entire assembly is regressed 2" into the luminaire housing for deep lateral shielding. Angled side panels with a high-reflectance, matte white finish direct light into a soft downlight distribution, with spacing criteria of 1.1. Choose from Specular (SPL) or Matte (MPL) louver finish.
Widespread Indirect Optics (WIO)
The Widespread Indirect Optic (WIO) consists of side-mounted LED arrays, coupled to an optical-grade acrylic light guide engraved with micro-structure optics that extract light into into the desired “batwing” distribution.
Peak intensity hits at 125º while suppressing direct uplight. Peak-to-zenith intensity ratio is 2:1, outstanding for a narrow luminaire. WIO produces noticeably smoother ceiling brightness than a typical lambertian uplight distribution, permitting generally wider spacing as well.
PoE
PoE technology can be integrated into many of Lumenwerx’s lighting solutions and product families. For nodes, we always aim for complete integration, but when space is limited, we look for a remote solution that doesn’t compromise the design aesthetic. PoE can be integrated into 95% of our product offering, including our Chromawerx solutions. See PoE webpage
