The square trim rounds out the Quadra family to provide wall wash capability. Careful lamp positioning above the glass spread lens optimizes uniformity. The Quadra Wall Wash has a strategically placed reflector and lens that optimizes uniform vertical illumination. The Lumenetix module mixes a broad spectrum of LED’s. This delivers dimmable white light that smoothly "warms" the color temperature from 3050K to 1800K, providing the soft luminance of a halogen light while maintaining a CRI value of over 90 through the dimming curve. The module produces a light consistency of less than 2 SDCM (MacAdam Ellipse).
