Ketra Lighting: The Next Evolution in Smart Home Illumination

How Tunable, Full-Spectrum Light Brings Wellness and Beauty to Your Home

Most smart lighting systems let you dim the lights or change colors from your phone. That's convenient, but it's also just scratching the surface. Ketra lighting takes it a step further—mimicking the way natural sunlight moves through the day, enhancing your home's appearance, and actually supporting your body's natural rhythms. If you're building or renovating a house, understanding what sets Ketra apart can help you make a smarter investment in your lighting.

Lighting That Mimics Sunlight

Ketra is different and more advanced than standard tunable lighting. Other systems can shift between warm and cool tones, but they're limited—typically ranging from 2700K to 3000K. Ketra covers a spectrum from 1400K (like candlelight) all the way to 10,000K (bright midday sun), which is a massive range.

But it's not just about achieving different white color temperatures. Ketra utilizes a four-channel LED system that combines red, green, blue, and white light to produce more authentic colors. The result is light that follows the natural progression of daylight—what lighting designers call the "blackbody curve." Your fixtures can automatically shift from energizing cool tones in the morning to soft, warm light in the evening, matching changing outside conditions. The dimming is smooth and flicker-free, going down to 0.1% without any visible stepping or harshness.

Making Your Home Look Its Best

Ketra has a feature called Vibrancy that no other lighting system offers. Think of it as a third control—beyond brightness and color temperature—that adjusts how light interacts with the colors in your space. You can make your artwork pop, bring out the richness in wood tones, or soften the appearance of fabrics, all without changing the actual color of the light itself.

The system also offers 16.7 million color options for accent lighting and special occasions. Color Lock technology monitors the fixtures 360 times per second to prevent the color degradation that happens with typical LEDs over time. Your lighting will look the same in five years as it does on day one.

Supporting Your Body's Natural Rhythm

There's a growing body of research on how lighting affects sleep, mood, and focus. Ketra's circadian lighting capabilities tap into this science. Cool, bright light in the morning helps you wake up and stay alert. As the day progresses, the light gradually warms, signaling to your body that it's time to wind down. This isn't just about comfort—it's about working with your biology instead of against it. Hospitals began using circadian lighting for patient recovery, and the benefits have naturally translated to residential settings.

Works Seamlessly With Lutron Systems

Ketra is part of Lutron, which means it integrates natively with Lutron HomeWorks, HomeWorks QS, and RadioRA 3 systems. The fixtures use wireless control—no additional wiring required—and can be managed through Palladiom keypads, the Lutron Connect app, or voice control. If you're planning a whole-home lighting system, Ketra represents the highest level of performance available today. 

Ketra represents a genuine leap forward in residential lighting—combining wellness benefits with visual excellence and smart home integration. It's not just about having another feature in your home. It's about creating an environment that looks better, feels better, and supports how you actually live. Ready to bring natural light indoors?
