Cubic LED ceiling light Q Four The four LEDs of the Q Four ceiling downlight are encased in a square construct with rounded corners. The light emission openings in the aluminium housing are formed in such a way that the light is focused and glare-free. The narrow beam enables accentuated lighting that can be used to emphasise objects and surfaces. If a phase dimmer or leading edge dimmer is added (not included), the light intensity can be dimmed using a conventional wall switch. Nimbus attaches great importance to durable quality made in Germany. Experimental, different, experienced - these are the cornerstones of the German manufacturer. With the pioneering ideas of managing director and architect Dietrich F. Brennenstuhl and his team and the characteristic design language of the products, Nimbus has established itself as a premium brand since it was founded in the 1980s.
