Collection of very rare, extra large (amazing diameter of 51cm) explosion-proof lamps ''OKs-2'' produced in socialist Polish factory''Zaos''. Dating back to late sixties and presenting rare first factory model of those lamps (later models had lower shade caps). Beautifully shaped cast iron shade caps with nice enamelled lamp shades with wire bulb protection and strong 1 cm thick textured tough glass. The lamps were used in old abolished communist factory, what is unusual is, above all, the colour, patina, signs of use that create an absolutely phenomenal original design. Lamps are E72 sockets adjusted (new metal ceramic sockets). Installation of the cables will be very easy what is shown on the last photos (all screws in exterior of lamps are authentic and goes well). Approx dimensions: Diameter:51cm, height: 44cm, weight: 10kg.
