Why Light Matters
Most homes are lit with a single, static, lifeless color of light.
Yet light shapes everything — how a room feels, how your art reads, how rested you are at night and how sharp you are by day. The world’s finest interiors are defined as much by their lighting as their architecture. Ketra, engineered by Lutron, is widely considered the biggest leap forward in lighting since the lightbulb itself: a light source that finally behaves like nature intended.
The Ketra Difference
Light engineered to behave like the sun
Precise Natural Color
Instead of plain white LEDs, Ketra mixes color to create white light that feels truly natural — a full range from a 1,400K candle glow to a 10,000K midday sky, plus a palette of 16.7 million colors.
Rich Color Rendering
Ketra Vibrancy is a first-of-its-kind “third dial” that remixes the recipe of white light to change how it renders color — bringing art, fabrics, finishes, and skin tones to life with museum-quality richness.
Color You Can Trust
Ordinary LEDs drift and discolor as they age. Ketra’s Color Lock technology measures light output 360 times every second, actively holding true, consistent color for the entire life of the system.
Native Wireless Control
Every fixture is individually addressable and wireless, largely eliminating control wiring and closet panels. Rooms can be re-zoned and redesigned over time without tearing open walls or rewiring.
A Day in Natural Light
Your home follows the sun
Ketra shifts gently through the day — automatically — so the light is always right for the moment and in tune with your body’s natural rhythm.
A soft, warm sunrise eases the home awake and the body into the day.
Crisp, daylight-balanced light boosts alertness for work, cooking, and getting ready.
Light eases back toward neutral, flattering every space and finish as the day cools.
A golden, sunset-warm scene relaxes the home for dinner and entertaining.
An amber, candle-like glow signals rest and protects natural sleep rhythms.

Good to Know
Questions, answered
Does tunable lighting really affect how I feel?
Yes. Light that follows the sun’s natural color temperature supports your circadian rhythm — energizing cool light by day, calming warm light at night — which research links to better focus, mood, and sleep.
Will it run automatically, or do I have to adjust it?
Both. Ketra can shift through the day entirely on its own to mirror natural daylight, while one-touch Lutron keypads and the app let you call up any scene instantly whenever you want.
Can I control everything from my phone?
Absolutely. Through Lutron HomeWorks you control lighting, shades, and scenes from elegant engraved keypads, your phone, or by voice — from anywhere in the world.
Do the fixtures and controls show?
They’re designed to disappear. Fixtures recess cleanly into the architecture and banks of switches are replaced by a single, custom-engraved keypad — only the feeling of perfect light remains.
Can it be added to my existing home?
In most cases, yes. Because Ketra is natively wireless, it can often be introduced and re-zoned without the major rewiring a traditional lighting overhaul demands. We assess every home individually.
