Industrial wall lamps produced in Czechoslovakia by Elektrosvit company in 1950s. The lamps are made of chrome with bakelite shield. Each one has a metal connecting piece that is used to screw the light onto something. This is how the light can actually hold on something. Ideal is a metal rod or wooden stick. The lamps were originally used in factories as a part of table lighting. The lights work as plug in lamps, each one works on one bulb and EU plug. Very good condition, some minor are and use wear visible. Great industrial pieces! Two available, price per light.
