roger arquer is a spanish designer now based in london, who designed the dramprom lamp that uses
condensation as a shade. first designed in 2005 and updated earlier this year, the dramprom lamp is made
from a customized glass vessel that is filled with some water. the light bulb is placed in a recess within the
glass, but not directly in the sealed container. when the light is turned on, the glass heats up and the water
inside begins to condensate on the glass, creating a shade for the light. the water drops create a soft
diffusion of the light, making the glass vessel glow.
