Using well-integrated lighting technology, the Kubus range of luminaires carries the ERCO principle of "Light, not luminaires" to positive extremes - less luminaire, after all, is hardly conceivable. The miniaturised light sources, inconspicuous, ultra-compact cuboids with robust housings made of cast aluminium, are completely immaterial compared to their striking lighting effect as floor washlights or facade luminaires. Their high energy efficiency and extended maintenance cycles are due to the modern metal halide lamps and LEDs.

Small luminaire, big effect: in the outdoor area, the lighting effects of Kubus are often enough to ensure good orientation and spatial perception. The Kubus facade luminaires can be mounted to emit their light either upwards or down-wards.
