The Delta ceiling light was originally designed for Inness, a hotel and resort in the Hudson Valley inspired by the natural surroundings. The rustic setting and traditional 18th-century lanterns inspired the shape of the Delta light, which has been stripped down to a minimum to give it a distinctly modern look. Three metal panels act as louvers, softening the light from the integrated LED source to create a pleasant glow.
