Most lighting is static. It does the job, but it often feels flat and unnatural, especially when dimmed. Tunable white improves on that. Lutron Natural Light brings it home.
It creates light that feels natural, elegant, and aligned with the rhythm of the sun. Clear light for the day. Warm light for the evening. A home that simply feels better, at every hour.
We’ve felt this rhythm since the beginning. Ketra brings it home.
Ketra follows the arc of the sun—cool and energizing in the morning, warm and calming by night. It brings natural rhythm back to indoor life.

From 1,400K to 10,000K—with full-spectrum whites and 16.7 million colors—Ketra gives designers total freedom to shape mood, texture, and tone in every space.
Minimal trims, quiet ceilings, and flexible optics make Ketra fixtures as intentional as the light itself—whether you’re washing a wall or spotlighting a sculpture.
With Ketra, every fixture reads the room and holds its tone and output over time. Whites don’t drift. Colors don’t fade. The design you create stays exactly as you intended.


Each Ketra fixture dims independently—no dimming panels, no ventilation planning, no control wiring. Just clean infrastructure and more space for living.
Ketra runs on simple line voltage and communicates wirelessly via Lutron Clear Connect Type X. No rewiring. No diagrams. No headaches.
