At first glance, Vetra could be no more than a traditional, old-fashioned, blown-glass lamp, but turning it on yields a surprise. Joan Gaspar uses a completely closed glass diffuser as a reflector, and creatively places the light source outside -instead of inside- the shade. The Vetra gives off more light than one would expect, without glare. Much of the light is directed downward, and the rest is filtered toward the inside of the shade, subtly illuminating it.
