The gentle glow from Kepler’s floating translucent circles seems to come from nowhere. The suspension lamp’s wide, luminous discs, suspended like pivoting makeup mirrors inside a slim metal frame, are finished with two sheets of silk-like micro-weave fabric pulled as tight as the skin of a drum. Light from a hidden ring of LEDs bounces back and forth between these two surfaces and multiplies across them for an effect that mimics a tunnel of light extending through space. (Hence the fixture’s name, an homage to the German astronomer who described a supernova in 1604.) It may sound scientific, but the look is pure magic.
