Table lamps are easy. Plug them in and you are done. But they come with tradeoffs.
The most obvious one is surface space. A lamp base can eat up a good portion of a nightstand or console. In a small bedroom, that space might be better used for books, a phone, or just breathing room.
Then there are the cords. Unless you have a floor outlet exactly where you need it, you are likely running a cord down the wall and across the floor. Even neatly tucked in, it adds visual noise.
Table lamps also tend to create pockets of light rather than filling a room evenly. That can be great for reading, but it may leave corners feeling dim. If they are your only source of light, the room can feel a bit patchy.
Height is another factor. Because the light source sits lower, the shadows fall differently than they would with a ceiling fixture or wall sconce. Sometimes that is cozy. Sometimes it just feels limited.
None of this makes table lamps a bad choice. They are flexible and easy to move around. But if you are trying to free up surfaces or clean up sightlines, wall mounted or ceiling mounted lighting might make more sense.
Every option has its pros and cons. It is about choosing the compromise you can live with.
