Energy-efficient LED ceiling light Otto O, dimmable via wall switch The Otto O ceiling lamp is one of HerzBlut's results of a successful fusion of warm wood and cold metal. The frame of solid wood and the metal plate with brushed nickel finish are coherently joined into a rectangle, so that the lamp makes a beautiful addition to modern hallways or living areas. When the room should not be so brightly lit, the combination of click&dim and dim-to-warm technology comes into play. This allows Otto O to be dimmed continuously via the existing wall switch and thus supports different moods in everyday life. As the brightness decreases, the lighting appears increasingly warmer (4,000-2,200K). Regardless of the colour temperature set, the luminaire has a high colour rendering index (CRI > 90), which means that the colours of illuminated objects appear very natural.
