French modernist  lamp  made in the 1970's  , by Jean Louis Domecq , under the name Lac . It is the original design ,  other extension can be  added  to extend the arms using the same principle. The particularity of the connection is the direct contact inside which does not required  wires so it can be manipulated  in any shape or form desired , all the moving part  possibly moving at a 180  %  angle  . This one is a 3 arm which was usually  the size of a working lamp for dentist , labs and even hair dresser , those could even  be  use as dryer with hot bulb . It can be use as a sconce using the original connector ( present) or mounted  as a desk lamp (presently on a cast iron base) .It has been stripped to the metal , with  some silicone  to protect against moisture. The name came from his initial J. L. D  ,  searching for a reliable and practical lamp to equip the machines in his workshop, Jean-Louis Domecq  designed and constructed his own creative version .This model was his last creation in the 1970's  , the quality of the metal and craftsmanship is not to be found anymore in the mass produced import of today .
