How Ketra transforms the feel of your home

Lighting is the single most underestimated element of interior design. The same room, with the same furniture and finishes, can feel completely different depending on the quality and color of its light. Ketra gives you control over that experience at a level that was previously impossible.

• Morning. Cool, bright light eases you into the day - energizing and clear, like stepping outside on a crisp morning. Your kitchen, gym, or office comes alive without a single switch being touched.

• Afternoon. Balanced, neutral tones support focus and productivity. Your home office, library, or studio feels purposeful and calm.

• Evening. As the sun sets, Ketra shifts to warm, amber tones that prepare your mind and body for rest - the way firelight or candlelight has done for thousands of years. Dinner feels intimate. Your living room feels like a retreat.

• Art & interiors. Ketra's Vibrancy control - a first-of-its-kind feature - allows you to adjust how light renders color without changing its temperature. Your paintings, sculptures, and architectural details are revealed in a way no standard LED can achieve.

• Night. Ketra dims to as low as 0.1% - virtually invisible - while maintaining the warm glow of a sunset rather than the flat fade of a conventional dimmer. Your home never feels harshly lit, at any hour.

Light that works with your body, not against it

Your body's circadian rhythm - its internal 24-hour clock - is governed primarily by light. When the light in your home is static, artificial, and disconnected from the sun's natural cycle, that clock drifts. The result is disrupted sleep, reduced energy, and a subtle but persistent sense that something feels off.

Ketra corrects this. By gradually shifting in color and intensity throughout the day - automatically, invisibly, without any intervention - Ketra keeps your body synchronized with nature's schedule even when you never step outside.

• Better sleep. Ketra's warm evening light supports natural melatonin production, signaling your body that it's time to wind down - leading to deeper, more restorative sleep.

• Sharper focus. Cooler daytime tones promote alertness and concentration - the same quality of light that makes you feel more awake on a bright morning.

• Improved mood & wellbeing. Exposure to natural-spectrum light throughout the day has been shown to improve mood, reduce fatigue, and support hormonal balance.

• Reduced eye strain. Ketra's smooth, flicker-free light and adjustable color temperature eliminates the visual fatigue caused by harsh, static overhead lighting — particularly during extended reading or screen time.

Wellness at home is no longer limited to air purifiers and fitness rooms. The quality of your light matters just as much.

The technology behind Ketra

• Four-channel light engine. Unlike standard LEDs that use a single white channel, Ketra mixes red, green, blue, and white light simultaneously - producing a far richer, more natural quality of white light that renders colors and surfaces the way natural sunlight does.

• Color Lock. Ketra monitors light output 360 times per second, automatically compensating to maintain perfectly consistent color throughout the lifetime of every fixture. The light on day one is the light on day ten thousand.

• Vibrancy. A unique third dimension of control that adjusts the spectral recipe of white light - revealing hidden depth in colors, textures, and artwork without changing the color temperature itself.

• Wireless & individually addressable. Every Ketra fixture is independently controllable via wireless - no control wire, no closet panels, no rewiring required to rezone or redesign your lighting layout.

• Seamless Lutron integration. Ketra integrates natively with Lutron HomeWorks and other Lutron control systems - the same platform controlling your shades, scenes, and whole-home automation through a single, elegant interface.
