IKEA clamp-style light. Color is silver. I was using it attached to a shelf next to my desk. It uses a screw-type fixture, so it can accommodate boards of various thicknesses. When removing it, the sponge on the contact part came off, so please attach felt pads or similar to prevent floor scratches when using it. (Photo 4) Since it could be fixed with only the scratch-resistant fixing金具, there are no screws to directly fix the bottom. The lower part of the switch has yellowed due to aging. E17 socket Maximum 40W Switch cord - Brand: IKEA - Model: V0401 - Voltage: 100V 50-60Hz - Maximum power consumption: 40W - Socket type: E17 - Clip material: Metal Thank you.
