Architectonic wallwashers: ERCO Quadra and Compact LED

Lüdenscheid, March 2014. Office buildings must meet high standards of functionality and efficiency. Even areas away from concentrated work in single offices or conference rooms, for example in hallways as connecting spaces or foyers as open features, present challenges in any architectural design concept. The right lighting helps the user perceive spatial dimensions intuitively. With the additions to the Quadra and Compact LED ranges now including lens wallwashers and double washlights to their existing diversity, ERCO now offers lighting tools of even higher efficiency for differentiated architectural lighting. Their exceptionally shallow recess depth makes them flexible products for use in any building project.

The illumination of vertical surfaces plays a crucial role in spatial perception. It allows the observer to perceive the form and dimensions of a space. Evenly illuminated walls make the entire space seem bright and give the impression of being almost intangible and bright. Moreover, creating the impression of brightness through vertical illuminance makes this type of lighting an exceptionally energy-efficient alternative. ERCO has now enhanced two established ranges of recessed luminaires to include wallwashing versions. Quadra and Compact LED, previously available with wide flood and oval flood distributions, now feature highly efficient lighting tools that open up new avenues in vertical illuminance: As lens wallwashers they are designed to achieve superb uniform illumination of walls, whereas the double wallwashers illuminate parallel walls efficiently in places such as hallways or corridors.

Quadra and Compact LED: Efficient and architectonic.
Especially in hallways and narrow corridors, the balancing act between scenic lighting for architecture and optimum visual comfort presents quite a challenge. The new light distributions of Quadra and Compact LED provide designers with a way to implement user-friendly lighting concepts as economical solutions: Installed in the ceiling, the unobtrusive, yet elegant recessed luminaires provide subtle and efficient illumination with excellent glare control. The uniform light distribution of the lens system, made of high-grade optical polymer, ensures precise and exceptionally uniform wallwashing that is second to none. Illuminating the ceiling and floor through diffuse reflection highlights both the architectural qualities of the room and the surface characteristics of the walls. The high level of glare control of the luminaires, meanwhile, ensures optimum visual comfort.

Innovative photometrics and functional design for perfect wallwashing

The combination of economic efficiency and visual comfort in Quadra and Compact LED is achieved using intelligent lighting technology that assimilates the collimator and Spherolit lens into a single unit. This effective design results in greater efficiency through uniform and wide light distribution: As compact lighting tools the luminaires can be spaced up to 1.5 times the wall offset allowing for exceptional grid dimensions. A further compelling argument for using these lighting tools in building projects is their particularly shallow recess depth, which ensures quality light even in areas with limited installation space.
