Architect's lamp from the 60s/70s

Very nice desk lamp, more specifically architect around 1970. Model made in france (see nf label in the diffuser). White satin metal arm and aluminum diffuser, this articulated lamp is attached to the desk tray by a screw-down clamp and can be oriented in all planes of the space (see photos). The arm has a maximum extension of 1m allowing the lamp to be installed on large worktops, the diffuser is 19 cm in diameter and 16 cm high. Finally the wire with switch measures 2m. The lamp is in perfect condition and is sold with its bulb.
