adjustable wall lamp
13 w × 11½ h in (33 × 29 cm)
The Sistrah lamps, short for Sie Strahlt Hell (She Shines Brightly), were created by C. F. Otto Muller at the Technical Light Institute at the Institute of Technology in Karlsruhe. The design was developed to create a light that was bright but focused the light in only the area that needed illumination. The lamp utilizes hand-blown and manufactured shades in clear and translucent glass to achieve this effect.
