A single light in the middle of the ceiling does one job well: it makes the whole room bright. It does that job the same way everywhere, from above, with nothing to look at and no place that feels like a nook. In the evening that is usually more light than you want and in the wrong place. The sofa is lit, the reading chair is lit, the dark corner is lit, and nothing feels special.
Lighting designers solve this by layering: several lights at different heights, each with a small job, which you mix to suit the moment. It is the cheapest way to make a room feel cosier, and often you already own most of the layers.
Ambient light is the general glow that lets you walk around safely. Usually it is the ceiling light, ideally on a dimmer, so you can turn it low or off in the evening. Task light is focused light where you read, sew or do a puzzle: a floor lamp beside an armchair, or a lamp on a side table at seated height. Accent light is the small, soft pool that gives a room depth: a lamp on a shelf, a light that grazes a picture or a wall.
A common rule of thumb for the total is around 100 lumens per square metre of floor, so a 20 m² living room needs roughly 2,000 lumens in all. Lumens measure how much light a bulb gives out, and the number on the box matters more than watts. For a feel of the scale, a bulb of around 450 lumens used to be sold as a 40 W bulb, and around 800 lumens as a 60 W bulb. Treat the 100 lumens as a starting point, not a target to hit: in the evening you will want less overall, and more of it low down and close to you.
Below is a living room seen from above, in the evening. Start with the ceiling light alone, then turn it down and add the lamps. Watch what happens at the reading chair, the sofa and the four corners. Then make the room bigger and see what the same lamps can still reach.

Try the evening mix and you will see the pattern. The ceiling light stays on but turned down, so it is only a quiet base. One lamp at the reading chair does the real work. One or two more at table or shelf height give soft pools of light you can rest your eyes on. Three or four sources at different heights is a good starting point for an average living room. A small room can manage with two or three, and a large or open-plan room usually needs a few more, so that each zone, such as the sofa, the dining table and the reading corner, has its own light.
You do not need to light every corner. The model above rarely does, and the room still feels warm. Light the places where you actually sit, read and walk, and let the rest stay shadowy; that is what makes a room feel deep rather than flat.
Two things keep layers feeling like one room. First, use the same colour temperature across all of them, warm white at roughly 2700–3000 K (kelvin, the number that says how warm or cool a bulb looks). Mixing a warm lamp with a cool ceiling light makes the room look patchy. Second, give each layer its own switch, and add a dimmer if you can: a dimmable bulb with a lamp that has a dimmer on its cord is an easy way to do it with lamps. Changing a ceiling light or fitting a wall dimmer is mains work, so leave that to an electrician.
Before buying anything, try moving the lamps you already have. A table lamp from the bedroom, a desk lamp turned to face a wall, or a floor lamp dragged next to the armchair often does more than a new light would. Second-hand lamps are an easy win, because the lamp itself is simple and a new warm-white bulb costs little. If you rent and cannot drill, a plug-in lamp on a shelf or a side table is the easiest accent light, and a smart plug or a cord switch lets you turn it on from the sofa.
A few safety basics: use LED bulbs, which run cool, and keep paper or fabric shades well away from hot bulbs. Keep cables out of the walkway so nobody trips on them, and fix tall, top-heavy floor lamps so they cannot be knocked over by a child or a pet.
On any budget, check these before you buy. Measure first: the space on the floor (the base of a floor lamp is usually 25–45 cm across), the height from floor to ceiling, and the distance from the chair or side table to the nearest socket, so the cable reaches without crossing the room. Look at the fitting (E27 is the large standard screw cap and E14 the small one) so you can choose a warm-white bulb with a number around 2700 K on the box. Check whether a bulb is included.
At a lower budget, a simple lamp with a stable base and a cord switch is plenty. A fabric or frosted shade is worth the small extra, because it hides the bulb and spreads the light softly. In the middle, look for a shade you can see through at a glance: you should see a warm glow, not a bare bulb. Make sure the height suits where you sit, and that you can dim it. At the top end, you are mostly paying for weight and stability, finish and a built-in dimmer. A heavier base is safer on a busy walkway. None of this is a must-have, and one good lamp in the right place beats three in the wrong ones.
