Natural Light. Better Life.

Our Story

Based in Austin, Texas, Ketra has revolutionized the lighting industry through the creation of a new category: Natural Light.

From the energizing midday sun to the familiar, soothing glow of a candle, Natural Light changes throughout the day, following the formula created by nature, synchronizing our circadian rhythms so that we live healthier, happier, more productive lives.

As we spend more and more time indoors, in front of screens and away from natural sunlight, our bodies aren’t receiving the stimulus they need to maintain proper health and rest. Ketra brings Natural Light into the built environment, and influences our overall wellness where we live and work.

Founded in 2009, Ketra has made dynamic light accessible in any environment with a flexible, fully integrated lighting and controls solution. Ketra’s tunable light creates high quality white, pastels and saturated color from a single-point source, enhancing the look of any space, and allowing you to tailor your light to meet your specifications.
