VIA 4

Direct, Indirect, Direct/Indirect, Flush and Wall Wash

Via 4 is the flexible linear LED luminaire system for pendant, surface, and recessed or in-wall installation, whether as discrete luminaires, continuous runs, or patterns. Via 4 features numerous high-efficiency optical configurations, flush, drop diffusers as well wall wash and asymmetric distributions, including separately controlled indirect/direct. With a wide range of electrical, control and trim options, Via 4 is also available in T5/T5HO & T8.

OPTICS

HIGH EFFICIENCY LAMBERTIAN OPTIC (HLO) - Matte white side reflectors combined with High-Efficiency Lambertian Optic (HLO) shielding of diffusing 0.075" thick acrylic with up to 88% transmission and good source obscuration. HLO is available as a flush diffuser or as a drop diffuser, extending 0.5" or 1.5" below the luminaire housing. Luminaire brightness is controlled by the flux-to-shielding area ratio.

Widespread Indirect Optics (WIO) - The LumenWerx Widespread Indirect Optic (WIO) uses two vertically oriented LED arrays that couple light into the edges of a linear light guide. A specially designed TIR/microstructure extracts light into the desired “batwing” distribution. Peak intensity hits at 120º while suppressing direct uplight. Peak-to-zenith intensity ratio is 2:1, outstanding for a narrow luminaire. The Widespread Indirect Optic produces noticeably smoother ceiling brightness than a typical lambertian uplight distribution, permitting generally wider spacing as well.

WALLWASH REFRACTIVE OPTIC V. 2 (WRO2) - The LumenWerx Wallwash Refractive Optic V. 2 (WRO2) delivers smooth vertical illumination with a gentle gradient and soft visual cut off. With peak intensity at 21º above nadir, the precise WRO2 configuration creates a strong downward component without shadows or hot spots. No external shielding is required. Microstructure material applied to the snap-in lens provides the precise refractive power and visual comfort, while achieving high luminous efficacy of 133 lumens per watt.

Direct ASYMMETRIC REFRACTIVE OPTIC V. 2 (ARO2) - The Lumenwerx Asymmetric Refractive Optic V. 2 (ARO2) has a directional Gaussian light distribution with peak intensity at 20º above nadir and 55º FWHM (Full Width at Half Maximum) beam angle. ARO2 uses a highly reflective finished reflector combined with a matte beam shaping diffusing film to create a smooth, effective downward component without shadows or hot spots. No external shielding is required. Microstructure material applied to the snap-in lens provides the precise refractive power and visual comfort, while achieving high luminous efficacy over 120 lumens per watt.

PATTERNS

At LumenWerx, we make it simple to design patterns customized for you. Whether surface, wall mount, pendant or recessed - or even a combination of different mounting types, we make it easy to achieve the results you're looking for. While our standard is a 90º corner, we can customize angles to suit your needs.

DOWNLIGHTS

Fixtures with Chip On Board (COB) technology are able to provide a maximum output of 1800 lumens from a discrete 50mm aperture on 8 inch centers. Standard CRI is 80, for 90 and 97 CRI with elevated R9 values please consult factory. Standard 20º, 30º and 40º beam angles are available, as are custom angles with prior factory approval. All our Chip-On-Board products have been tested in accordance with IESNA LM-80-08 and the results have shown L80 lumen maintenance greater than 50,000 hours.

CHROMAWERX

Chromawerx Sola is single-channel control that dims output while warming the color temperature in a pre-determined relationship. A simple digital or analog control sends a common signal to dual output digital drivers, which are programmed to adjust a specially populated LED array to emulate the effect of dimming a filament source. Dimming range is programmable but the default option runs from 3500K at 100% of full power to 2700K at 5% of full power. CRI is maintained above 80 throughout the dimming range.

Chromawerx Duo is two-channel control. It uses analog or digital protocols for synchronous control of both warm and cool LED arrays, enabling the user to set color temperature and light output. Commonly called “tunable white”, Chromawerx two-channel control provides the range of warm (2700K) to cool (6500K) color that can be useful for helping to entrain circadian rhythms, stimulate alertness for improved educational and work productivity, and compensate for jet lag, among other applications. The Chromawerx drivers are programmed to limit maximum light output and power usage across all color temperatures. CRI is maintained above 80.

Chromawerx Quadro is a four-channel control that operates an RGBW LED array and addresses the need for more expressive color in architectural applications. The DMX driver supports familiar programming tools for both dynamic multi-hued color and precise white color point control. While a typical user interface will be a DMX controller by others, Lumenwerx also offers a simple control station for stand-alone color changing applications.

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
