Ketra Lighting
Lutron's full-spectrum light source - sunlight indoors, from sunrise warmth to midday clarity.
Light that lives like the sun
Ketra, by Lutron, is the finest interior light made: full-spectrum LED sources that shift color temperature and intensity through the day, matching the sun's arc - energizing morning white, honeyed evening warmth - automatically, in every fixture.
Artwork reads true, skin tones flatter, and evenings wind down naturally. Designed with Adom Smart Home and choreographed with our Lutron shades, Ketra completes homes where light is taken seriously.
