The Ketra Light Everyone Wanted — Now Small Enough to Disappear
June 29, 2026
Now on demo in our showroom — round and square.
For years, choosing Ketra meant accepting a compromise. You could retrofit the most natural, tunable, beautifully rendered light on the market — but only through a 5 inch aperture that announced itself on the ceiling. That trade-off is over. The new Ketra D2R brings the full Ketra experience into a clean, modern, small-aperture form factor — and we have both the round and square versions on demo in our showroom right now.

WHY THIS IS A BIG DEAL
Until now, true Ketra light wasn’t really on the table for most finished homes. The original retrofit downlight was large — closer to a five-inch presence on the ceiling than anything a designer would specify today. The D2R changes the equation. It’s a remodeler downlight, which means it installs into a ceiling that’s already finished, through a hole roughly the size of a standard small recessed light. In plain terms: this is the first time you can add Ketra to a home that’s already built — without tearing the ceiling apart, and without giving up the tight, architectural aperture modern interiors call for. That effectively puts this light within the reach of far more people.
“HOW BIG OF AN OPENING DO I NEED?”
It’s the first question everyone asks, so here it is up front. The D2R is a true small-aperture fixture with roughly a two-inch aperture. The ceiling cut-out depends on how it’s mounted:
→ Flanged retrofit — about a 3⅛″ (3.13″) hole. This will be the most common use case for most people.
→ Flangeless mud-in — about a 4″ hole
→ Flangeless millwork — about a 2¾″ (2.83″) hole
It fits ceilings from ½″ to 2″ thick, the emitter tilts up to 40° and rotates a full 360°, and it comes in round or square, with a bevel or pinhole aperture and a range of trim finishes — so it can read as a clean white wash or all but disappear.


THE LIGHT ITSELF
Everything that made people fall in love with Ketra is here:
→ A full range from a warm 1,400 K candlelight all the way to a crisp 10,000 K daylight — 16.7 million colors.
→ Dimming down to 0.1%, smoothly — the way incandescent used to dim.
→ Very high color rendering when you want it: CRI above 90 and R9 above 90, so skin, art, wood, and fabric all look the way they should.
→ Dynamic shifting through the day, mimicking natural daylight on its own — plus Vibrancy, the richness flat white LEDs simply can’t reach.
→ Color Lock and full addressability: every fixture holds its exact color point over its lifetime, and each one can be controlled individually.

This is light that does what daylight does — and then keeps going after the sun sets.
WHAT YOU NEED TO RUN IT
The D2R is part of the Lutron HomeWorks QSX ecosystem. To run it, you’ll need a Homeworks system with a dual RF processor or QSX wireless gateway that supports Lutron’s Clear Connect Type X — the wireless backbone these fixtures communicate on. If Homeworks is already in the home, adding Ketra is now genuinely straightforward.
BUILDING NEW? IT SOLVES A PROBLEM THERE TOO
The D2R isn’t only a retrofit story. In new construction, when you can’t accommodate a pot light with a significant housing, the D2R offers a way to bring Ketra into tightly framed ceilings. It’s as much a problem-solver for a new-build as it is for the finished home.
COME SEE IT. FEEL IT.
Specifications only tell you so much. Ketra is something you have to stand under — the warmth of it at night, the snap of it at full daylight, the way a whole room changes when the light does. We have the round and square D2R demos on hand, and the only way to truly understand what they can do is to experience them in person.
