Founded in 2009 by a trio of Austin entrepreneurs, Ketra has revolutionized the lighting industry by creating dynamic LED lighting solutions that emulate natural light. Their mission is to make light an integral part of the human experience, leveraging cutting-edge technology to transform how we illuminate our spaces.

Ketra's product offerings include tunable LED lamps, luminaires, and integrated control systems designed to adjust color temperature and intensity throughout the day, aligning with natural circadian rhythms. These innovations aim to enhance well-being by bringing the benefits of natural light indoors.

In 2018, Ketra was acquired by Lutron Electronics, a leader in lighting controls and shades. This partnership combines Ketra's advanced lighting technology with Lutron's expertise in control systems, offering seamless integration and personalized lighting experiences.
