Ketra Tunable Lighting Systems, Perfected

Discover the power of tunable lighting systems that bring depth, precision, and warmth to luxury homes across Houston. Shape your interiors through light that responds beautifully throughout the day.

Custom Lighting with Infinite Colors

Ketra tunable lighting systems unlock the full power of the visible spectrum, giving designers precise control over tone and saturation. Whites feel intentional. Accent colors feel curated. Every surface reads exactly as intended under light designed to complement materials, finishes, and furnishings.

A Dynamic, Bespoke Approach to Interior Lighting

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.

Composed of Multiple Light Sources

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.

Natural Light, Thoughtfully Recreated

Ketra lighting mirrors the progression of daylight with exceptional accuracy. Color temperature shifts smoothly, dimming remains consistent, and interiors gain a sense of rhythm that feels calm, focused, and visually engaging throughout the day.

The Benefits of Natural Light

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.

How Ketra Mimics Natural Light

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.

High‑End Fixtures with Designer Precision

Custom lighting systems built with Ketra fixtures deliver remarkable color accuracy and optical control. Each fixture performs with purpose, allowing our Ketra lighting designers to highlight architecture, artwork, and textures exactly where clarity matters most.

The Color Rendering Index

The color rendering index is the primary way to gauge the quality of lighting fixtures and how well they will interact with specific colors.

What it is

Why it Matters

LED sources with a CRI of 90 or above boast excellent color rendering capacity, faithfully revealing the colors of your interiors and artwork.

The Power of Precision Optics

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