Combat Winter Blues with Lutron Circadian Lighting

Every once in a while, something truly revolutionary comes along that changes everything.

We've seen it before. Natural sunlight—bright and energizing in the morning, warm and gentle in the evening—has guided human life for thousands of years. It wakes us up. It lifts our mood. It helps us sleep deeply at night. But in our modern world, especially here in Knoxville during ongoing winter months, we spend too much time indoors. Shorter days. Cloudy skies. Early sunsets. And suddenly, we're tired all day, struggling with low energy, foggy focus, even the winter blues.

Today, I'm excited to tell you about something extraordinary. Something that brings the power of natural sunlight indoors—not just to illuminate your home, but to transform how you feel, day in and day out.

It's called Lutron Ketra.

And it's not just lighting. It's human-centric lighting that mimics the sun's natural rhythm perfectly.

Imagine waking up to light that gradually brightens, warm and bright like a sunrise—boosting your alertness, sharpening your focus, kicking off your day with real energy. Through the day, it stays crisp and vibrant, just like midday sun—helping you stay productive, lifting your mood, fighting off that seasonal fog so common in East Tennessee winters. Then, as evening comes, it softly shifts to warmer tones, like a golden sunset—signaling your body to unwind, promoting natural melatonin, and preparing you for restorative sleep.

It's grounded in science. By aligning your indoor environment with your body's natural circadian rhythm, Ketra helps reduce symptoms of seasonal affective disorder, increases daily energy, enhances mental clarity, and supports overall well-being. No more battling artificial glare or the drain of short days.

At iSS, we've been partnering with Lutron for years to bring this magic—including the incredible Ketra system—to homes throughout Knoxville and East Tennessee. We integrate it flawlessly for you, giving you effortless management through the app, voice commands, or elegant keypads.

Custom scenes are tailored to every room. Reliable performance, stunning aesthetics, and impressive energy efficiency—all in one seamless system.

And that's the beauty of it. This isn't a collection of separate features: pretty lights here, smart controls there, health benefits somewhere else. It's one unified experience.

Now, imagine bringing that same transformation into your own home—feeling more energized, sleeping more deeply, and thriving with greater vitality, even when winter days are at their shortest.

At iSS, we're here to make it remarkably simple for you. Give us a call today at (865) 690-0154, come visit our welcoming showroom in Knoxville where you can experience Ketra firsthand, or explore everything it offers on our Automation page and at ketra.com.
