Ketra reproduces the full spectrum of natural light — 1,400K candlelight to 10,000K daylight — and shifts it through the day exactly like the sun. Try it below: drag the sliders, tap a lamp.
Most lighting is one color, forever. Ketra is alive. Its Natural Show programming moves your entire home through the same arc as the sun — cool, energizing light in the morning, clean neutral white for focused afternoons, and warm, relaxed amber as the evening winds down. You stop noticing the light and start feeling better in it.
Every S38 and S30 lamp and every D3 linear fixture is individually addressable, so a single room can hold multiple layers of light — art accents at high vibrancy, cove lighting drifting with the daylight, a reading lamp locked to your preference.
Ketra runs natively on Lutron HomeWorks, which means the same Palladiom keypads, the same app, and the same rock-solid reliability as the rest of your lighting. We design the fixture plan, tune every scene on site, and calibrate vibrancy so finishes, artwork, and skin tones look exactly right.
1,400K–10,000K tunable white plus fully saturated color — one fixture covers candlelight, daylight, and everything between.
Circadian programming that tracks the sun automatically, every day of the year, with your own overrides layered on top.
S38 and S30 lamps for existing cans and fixtures, D3 linear for coves and slots — individually addressable, uniformly perfect.
On-site calibration for art, stone, wood, and skin tones — the gallery-quality difference you can see but can't fake.
