Varychrome technology opens up many new application areas for LED orientation luminaires. They add coloured accents and convey differentiated information. As dynamic and coloured points of light, they can interact with the architecture and its users. Their special optical components make these orientation luminaires highly visible even in bright surroundings. DALI-compatible control gear allows them to be controlled with the ERCO Light System DALI lighting control and the integrated software: ERCO Light Studio.
