These lamps date to the 70s or 80s but they are reminiscent of the very stylish Art Deco style.  The triangular shape is chrome and they are mounted with very quick perspex or lucite.

The lamps have individual slide controllers on the side, which are dimmer switches I think.  They are unmarked, but I think they could be Italian.

Condition is excellent, just some very minor chips to the perspex.
