Mid-Century Modern Arc Floor Lamp with Amber Dome Shade, Walnut Finish

One standard E26 or E27 bulb, up to 40 watts incandescent or the LED equivalent. A warm white LED around 2700K suits the amber shade and keeps the light soft. Skip a clear bulb with a visible filament here, the shade is meant to spread the light rather than show it off.

Up to 39 inches, or 100 cm, measured sideways from the base. That is enough to stand the lamp beside a sofa and have the shade hang over the middle seat instead of over the armrest.

The arm slides in, so you can set it shorter if the lamp has to sit closer to a chair or in a corner.

No. It plugs into a standard US outlet on a 98 inch cord and the switch sits on that cord, at floor level. There is no junction box, no ceiling work and nothing for an electrician to do, which is why it works in a rental.

No. At 65 inches it stands about head height, and a standard 8 foot ceiling leaves roughly 30 inches of air above the arc. The light comes down from the shade rather than up at the ceiling, so a low ceiling does not wash out.

Acrylic, not glass. It diffuses the light the same way, and it survives a knock, which counts on a lamp that stands on the floor next to furniture. The body is metal in a walnut finish.

Dust the shade and the arm with a dry microfiber cloth every couple of weeks. The inside of the shade collects more than you would think on a lamp that points down.

For marks, use a barely damp cloth and dry it after. Keep alcohol, solvents and abrasive pads away from the acrylic, they leave a haze that does not come out. Switch the lamp off and let the bulb cool before you clean it or change it.

Check the cord and the foot switch now and then, and keep the arm pointed away from the walkway so nobody catches it.

No. It is made for dry indoor rooms. A covered porch still gets damp air, and a bathroom gets steam, and both reach the socket and the cord.
