Product Details
Overview
The Ketra A20 lamp brings the world's most innovative full-spectrum light to wall sconces, decorative pendants, and table lamps. This proprietary four-channel light engine produces a wide range of white light (1,400K-10,000K) in a manner that makes the light feel more natural than other LED sources of white light and renders objects more faithfully. With over 70 patents, Ketra's 4-channel light engine produces unprecedented Natural Light, featuring Vibrancy control that allows customization of how light renders color without changing the color temperature itself, and Color Lock technology that ensures consistent performance throughout the lamp's lifetime. Control the Ketra A20 with the location-aware HomeWorks, Athena, and myRoom XC control systems to dissolve the boundary between the interior and exterior with sun-tracking precision that encompasses everything from the warmth of candlelight to the cool, pure brilliance of arctic skies.
