Ketra

You don’t have to settle for a limited color temperature index with Ketra’s dynamic white lighting, which delivers the broadest spectrum in the industry of 1,400K to 10,000K. Experience a tunable lighting solution that provides the tools—from white hues to soft pastels and saturated colors—to hone your interior design and lifestyle.

Tunable white light typically features “warm” or “cool” light sources limited between 2,700K and 3,000K. Ketra fixtures contain multiple primary light sources, which combine their unique spectrums of light for a greater color gamut that designers can dial in for any application or aesthetic.

Reproduce the warm glow of a candle or a crisp midday sky with Ketra’s High Def Palette, a four-channel LED system composed of red, green, blue and white LEDs. Its proprietary mixing and driver technology allows for unlimited flexibility without sacrificing the fixtures’ color rendering.

We’ve evolved into seeing natural light as a guide, and we work and respond to its conditions. However, the contrast of cool LEDs inside with warm sunlight hues outside creates a disconnect that affects our comfort and wellbeing. Eliminate this disconnect with Ketra for better rest, relaxation and focus.

Ketra’s Natural Light solution tunes along the blackbody radiation curve of natural light through correlated shifts in color temperature and intensity. As the sun gradually shifts, schedule Ketra’s Natural Light to match the light outdoors throughout the day without you having to lift a finger.

Using the power of reflection and refraction, precision optics allow designers and homeowners to deliver lighting exactly where they want it.

Adjust only the individual colors needed at a given color temperature to ensure a richer illumination that bounces off objects just the way you want.

Preserve the ideal lighting for years with calibration and preservation systems that monitor light output to ensure no color degradation over the fixture’s lifetime.
