Why your room feels cold at night — and the 3-lamp fix

If a room feels fine in daylight and hostile after dark, the furniture is not the problem. One overhead light is.
Why one ceiling light fails
A single source directly above throws everything downward. Faces get shadowed, corners go black, and the room shrinks to the size of the bright patch under the fitting. Three lower sources at different heights do the opposite.
Lamp one: the reading light
Beside wherever you actually sit, with the shade bottom at about eye level when seated — roughly 100–110cm from the floor. This is the lamp that gets used every evening.
Lamp two: the corner
Put light into the darkest corner of the room, not the prettiest one. A floor lamp or an uplight works. Lighting a corner is what makes a room read as larger after dark.
Lamp three: the low glow
Something small at 40–70cm — on a shelf, a sideboard, the floor behind a plant. It does almost no useful work and does all of the atmosphere.
Get the bulbs right
2700K, dimmable if you can. Matching colour temperature across all three matters more than matching the lamps.
