Unmatched Execution
Two-Inch Aperture
The only two-inch downlight with Ketra quality of light. Breakthrough optics and a smaller aperture allow the fixture to disappear into the ceiling, placing the focus where it should be—on the light itself.
Aim and Focus—Radically Reimagined
An exacting, easy-access tilt-and-rotation system allows you to fully leverage Ketra’s patented TruBeam optics, placing light precisely where you want it—and nowhere else.
Artful Attention to Detail
Harmonize ceiling aesthetics with the home’s design details. D2 trims are meticulously sculpted in die-cast aluminum, honed to a fine, nearly invisible edge, and painted to maintain a smooth, flush
