Nature perfected lighting a long time ago.
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.
Who We Are
We’ve taken the formula provided by nature and put it into every Ketra product. Designed and executed by Ketra — from proprietary chip to intuitive commissioning tools, we are a complete solution for lighting and controls.
