Ketra D2 Downlight from Lutron Offers In-Field Adaptability


The Ketra full spectrum D2 recessed LED downlights from Lutron are available in fixed, adjustable, and wall-wash options to complete any lighting design project. Using a system of interchangeable parts and components, each D2 downlight can be customized to meet the design and architectural needs of the space in which it lives.

No other light source more closely replicates natural light, from candlelight to moonlight. With over 70 patents, Ketra full spectrum Natural Light redefines how light in the home should feel.

Breakthrough optics and a smaller aperture allow the two-inch downlight fixture to disappear into the ceiling, placing the focus where it should be—on the light itself. An exacting, easy-access tilt-and-rotation system allows users to fully leverage Ketra’s patented TruBeam optics, placing light precisely where its wanted —and nowhere else.

D2 trims are meticulously sculpted in die-cast aluminum, honed to a fine, nearly invisible edge, and painted to maintain a smooth, flush-to-the-ceiling appearance.
