Varychrome technology with RGB colour mixing was a key factor in the breakthrough of LEDs in architectural lighting. For the first time, LED luminaires provided a combination of features that could not be implemented using conventional technology: flexibility and variability as well as comfort, long life and efficiency.

Their capacity for superb dimming and highly saturated light colours make LEDs the ideal light source for colour mixing luminaires. ERCO now presents a new generation of LED varychrome spotlights that mark a clear advance, especially in terms of versatility and light quality, arguably the most flexible tools for accent lighting and wallwashing ever provided.

These new developments are based on the principle of adding white LEDs to the primary colours red, green and blue (RGB). Addressing these four components individually and using a DALI-compatible 4-channel control gear means highly saturated light can be produced together with pastel hues, but more especially so, it provides high-grade white light with variable colour temperature – infinitely variable along the Planckian locus. The additional warm white component (3000K) also ensures excellent colour rendition.

ERCO’’s varychrome spotlights now combine the RGBW colour mixing available in the Quintessence range of recessed luminaires since 2010 with the patented LED optical system consisting of collimators and Spherolit lenses. As a specific feature, the varychrome spots have a light mixing layer integrated in the primary optical system to produce homogeneous beams without colour shadows. The Spherolit technology provides a wide variety of light intensity distributions from spot to flood and wide flood all the way to oval flood and wallwash.
