Ikea Silver-coloured desk lamp.
It is what we think is called "angle poise", ie you can bend the stem in various directions to angle the light as needed.
It is a quite heavy & solid lamp, and has a European two pin plug. On-off switch is on the lamp stem head.
Size appproximations: top to bottom, if you stood it up fully straight with no angling, about 60 cms tall. Base is about 19cms diameter. Screw-in bulb (included). See pix.
