A Lighting System Built for the Century Ahead

Ketra is the most natural, beautiful light source on the planet—like bringing sunlight indoors. It reveals textiles, stone, and finishes exactly as they were meant to be seen. No control wires. No panels. Just flawless, quality light that transforms the way luxury homes are designed, built, and lived in.

Light That Behaves Like Natural Daylight

Ketra picks up where natural daylight leaves off—seamlessly extending the quality of outdoor light into the home. It feels consistent, intuitive, and appropriate at every time of day, enhancing the space without ever calling attention to itself. No settings to manage. No modes to select. Just light that always feels right.

Light that feels naturally in rhythm

As morning begins, the space fills with crisp, energizing light. As the day softens, so does the tone—warm, calm, and inviting by evening. It doesn’t need managing. It just feels right, like the light is responding to the world outside your windows.

Full-spectrum control, down to 0.1%
With full-spectrum light from 1,400K to 10,000K and smooth dimming down to 0.1%, Ketra delivers performance that matches its beauty. This is the lighting tool you've been waiting for—the paintbrush that brings your design to life. It’s a revolutionary light source with 16.7 million colors—not for show, but to ensure every material, finish, and moment feels exactly right.

See your materials the way you fell in love with them

You’ve stood in a stone yard or fabric showroom, holding something to the light and thinking: this is it. Then you get it home—and it feels off. For the first time ever, Ketra fixes that.

Programmed for beauty, room by room

Ketra brings materials and finishes to life with warmth, glow, and richness that holds at any time of day or dim level. After installation, our team works with you to fine-tune each light for its room and purpose—so your home looks exactly the way you imagined it would.

Lighting’s first real innovation in decades
Backed by dozens of patents, Ketra is a breakthrough in lighting science. It doesn’t add artificial color—it manipulates the white light itself to bring out the beauty that’s already there. Stone, fabric, and paint appear more dimensional, more vibrant, more natural.

Unbelievable light quality, from a fixture you’ll barely notice

You see the light—but not the light source. Ketra’s D2 downlights are small, sculptural, and disappear into the ceiling, so all you see is beautifully lit space—not glare or hardware.

Minimal form, maximal performance

D2 comes in a 2" fixed or 3.5" adjustable housing, both with a 2" aperture that disappears into the ceiling. The adjustable adds tilt and rotation for art or architectural accents. Field-changeable optics, tool-based hot aiming, and beam angles from 15° to 60° give you full control. Die-cast trims taper to 0.02" and sit flush for a clean finish.

Color that holds—for years to come
Color Lock™ monitors each fixture’s output 360 times per second to ensure uniform color and brightness across the home. From install to years down the line, the lighting remains true to your original design intent—no drift, no rework.

Less wiring, fewer headaches, and more room for things that matter

Ketra was engineered not just to light better—but to build smarter. It removes bulky panels, extra wires, and surprise costs, while giving your builder and electrician room to breathe.

No dimming panels

Each Ketra fixture dims on its own, so you eliminate panel clutter and reclaim closet space—no ventilation planning, no large-scale load maps.

Just line voltage—no control wires
Fixtures are wired like standard lighting, then communicate wirelessly via Lutron’s Clear Connect Type X RF—keeping your low-voltage plans clean and your trades separate.
Flexible zoning without rewiring
Because everything is controlled through Lutron HomeWorks QSX, zones and scenes can be changed in software—even after move-in, furniture shifts, or new art is hung.
Precision control—no ladder required
Dimming curves, warmth levels, and vibrancy are all software-defined—fine-tuned without ladders, lens changes, or rewiring. The lighting adapts as the space and needs evolve.

Lighting, Elevated

Ketra isn’t a fixture line—it’s a rethink of how high-end homes are lit, built, and lived in. It honors materials, simplifies construction, and transforms what light can feel like in a space.
