Lüdenscheid, April 2025. As an integral element of architecture, light connects buildings to their context. It guides users seamlessly from inside to outside, contributing to a coherent narrative. Designers seek holistically designed lighting tools to achieve this effect. The new Iku downlight range by ERCO meets these demands for both new buildings and renovations: offering luminaires for outdoor use, in recessed and surface-mounted versions.
Modern architectural and urban planning concepts increasingly blur the boundaries between inside and outside, deeply integrating a building's spatial context. Design and usage processes follow a unified story, and lighting should also accompany users consistently, offering a holistic architectural experience. This is accomplished with lighting solutions conceived as holistic systems from the outset - such as ERCO's Iku downlight range. It blends the philosophy of perception-oriented lighting with exceptional energy efficiency, providing tools for almost any outdoor application with recessed and surface-mounted ceiling luminaires.
Iku brings the ERCO quality of light from the interior to the exterior: The new recessed and surface-mounted luminaires make Iku the product family for perception-orientated lighting concepts for outdoors. Wallwashers make the vertical surfaces of architecture visible. Downlights provide pleasant light and excellent visual comfort for all activities. Iku comes with exceptional efficiency, delivering more than 120lm/W.
Iku outdoor recessed and surface-mounted luminaires maintain exceptional light quality even under harsh conditions like moisture or dust. Featuring corrosion-resistant materials, they are designed for long-term durability, in line with ERCO's Lighting Durability philosophy, which aims for a minimum service life of 20 years.
Iku outdoor versions adhere to the "AAA" formula - Architecture, Activity, Atmosphere - offering downlight characteristics wide, extra-wide and oval flood distributions, and supplementing horizontal ambient lighting with vertical illuminance levels that are key to visual perception, such as on wall surfaces or facades.
For small and large lighting tasks: With 3 sizes and up to 6000lm, Iku covers a wide range of applications - always scalable to the current project. They offer more light with fewer luminaires. The special light distributions for pathways, open spaces or the uniform illumination of facades enable particularly large spacing between luminaires. This minimizes investments and energy costs.
The AAA formula also incorporates digital connectivity and dynamic light colours for creating the perfect ambiance at any time of day or night. Bluetooth Casambi for wireless control is also available as options in the Iku range for the new luminaire families. The Iku range therefore offers high visual comfort, smart dimmability and vertical lighting with maximum performance. Iku recessed luminaires embody the "light instead of luminaires" principle, while the surface-mounted versions allow up to 10,000 custom colours via the "ERCO individual" service to add design accents.
