A human-centric lighting downlight system: the new Iku recessed downlights from ERCO. People and their daily activities are the focus of lighting design. As a consequence, Human Centric Lighting (HCL) is a fundamental approach to planning. ERCO has now created the Iku recessed downlight system for premium HCL concepts. Tunable white is just one of several features for flexibly and dynamically combining architecture, activities and atmosphere in the lighting concept. 

The new range of recessed downlights meets all of the above requirements: Iku for all areas of architectural lighting and Iku Work specifically developed for standard-compliant workplace lighting. With its logic and clarity, the Iku system already starts impressing at the planning process: five sizes ranging from 84 to 221mm, three downlight distributions plus wallwashers and double wallwashers as well as six white light colours plus tunable white are all winning features. Iku recessed downlights are compactly designed and offer high lumen output with a luminous efficacy of over 100lm/W. Iku thus represents a universal system for uniformly designed, ceiling-integrated lighting. The range is ideal for public buildings, offices and administrative buildings as well as for conference centres, hotels and restaurants – and especially for realising successful HCL concepts.

Iku features modern interfaces for networking, e.g. with DALI or wirelessly via Casambi Bluetooth. It also includes Iku Work downlights, designed to meet the special requirements of workplace lighting (EN 12464) in offices and featuring standard-compliant UGR (approx. 60°) and oval wide flood (approx. 60° x 80°) distributions; they also have a DALI interface with through-wiring as standard.

Iku recessed luminaires feature perfect dimming behaviour down to 0.1% and flicker-free light for disturbance-free video calls. With their consistent appearance, mounting rings for covered or flush installation and based on the familiar sizes of the ERCO downlight ranges, Iku and Iku Work merge into a unified, single system: ideal for effortlessly implementing HCL lighting even in large and complex projects.
