Green lighting with a twist

Not so much a twist as a curve, really: a light shelf�a reflective shelf installed beneath a transom window or ceiling-line skylight to bounce the sun’s rays onto the ceiling�is one of the simplest ways to bring daylight into a room. Brightshelf gives this simple solution a twist, curving the reflective surface to spread out the sunlight across the ceiling rather than focusing it on narrow band.
