Early evening in late fall, when the sun drops out before you've even started dinner and the overhead light makes the whole room feel like a dentist's office, that's when a good modern lamp earns the switch flip. Clean lines, no fringe, no frills, just a shape that throws warm light low into a room instead of blasting it from above. Those are the nights I notice which lamps I actually reach for and which ones are just sitting there being sculptural.
Check the base before you buy it, not after you've unpacked it on the kitchen table. A lot of modern lamps are top heavy by design, that's the look, so pick it up and feel where the weight sits. If it wobbles when you nudge the shade, it will get knocked off a side table eventually, usually by a cat or a toddler or a guest who's had one too many. Look at the switch too, inline switches on the cord are fine, but a lamp with the switch buried under the shade where you have to feel around for it in the dark gets annoying fast. On delivery day, check the cord length against where your outlet actually is, because a six foot cord looks generous until the outlet is behind the couch and now you've got a lamp sitting three feet from the wall with a visible extension cord running across the floor. As for wear, metal bases in brass or black powder coat hold up for years with just a wipe down, no real aging to speak of. Marble or concrete bases are heavier and feel solid, but marble will show a water ring if you set a sweating glass on it, so keep a coaster habit going near the base. Fabric shades yellow a little over a few years near a sunny window, linen more than cotton, so keep them out of direct light if you want the white to stay white.
For color, matte black and warm brass are the two that never look dated and go with almost anything you already own, brushed nickel is close behind if your other metals in the room are cooler toned. Stark white ceramic can look clinical unless the shape has some curve to it. If someone has no modern lamps at all, start with one simple table lamp in warm brass or matte black with a plain linen shade, something around twenty four inches tall, and put it on whatever surface sits at eye level when you're seated nearby, a side table or a low dresser.
Next to it, I'd put a small dish for keys or reading glasses, something with enough weight that it doesn't slide when the cord gets tugged.
