Ketra


Natural Light. Better Life.

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.

The Ketra lighting products are aligned with Spire’s commitment to design and high performing technology. It takes an advanced manufacturing technique and accurate calibration to produce a specific illumination that gives a high quality of light and can also work nicely as a design element in a domestic environment.

Ketra Natural Lighting

Advanced Technology for Beauty & Wellness

Crisp and bright during the day, soft and warm in the evening. It isn’t hard to recognize, because it’s been with us forever — flawless and fluid, delivering just what our bodies need, exactly when they need it. From the energizing midday sun to the familiar, soothing glow of a candle: it looks beautiful, feels comfortable, and never requires our intervention.

Ketra has taken the formula provided by nature and put it into all their products. Designed and executed by Ketra — from proprietary chip to intuitive commissioning tools, they offer a complete solution for lighting and controls.

Until now, dynamic lighting of this kind has been inaccessible in the consumer space because of cost and implementation complexity. Ketra has created a system of fixtures and controls that all work together – something that has never been done before – and delivers ease of implementation as well as superior performance.
