Most rooms feel cold because of one light: the ceiling lamp. Replace it in the evening with two or three low, warm lights and the same room feels like a different place.

Two numbers decide how a light feels. Colour temperature in kelvin (K) tells you how warm it looks: 2700K is the classic warm white, 3000K is still warm, 4000K is neutral office light. Brightness is in lumens: around 800 lumens is roughly a classic 60-watt bulb. For a cozy room, choose 2700K to 3000K and spread the lumens over several lamps instead of one strong one.
Battery lights with a timer are the renter-friendly way to add the accent layer, because you need no outlet and no drilling.
Light at eye level feels cozier than light from above. Put lamps low and to the side, and aim fabric shades at a wall so the light bounces back softly. A desk light belongs on the side opposite your writing hand, or above the screen, so your hand does not throw a shadow. Keep bare bulbs out of your direct line of sight from the sofa or the bed; glare is the fastest way to make warm light feel harsh.
You do not need an electrician. A floor lamp replaces the ceiling light, curtain lights hang from the existing curtain rod with clips, and LED strips stick to the back of furniture rather than the wall. Battery lights with a timer remove the cable problem in corners without an outlet.

2700K is the classic warm glow and the safer choice for bedrooms and living rooms. 3000K looks slightly cleaner and suits kitchens or rooms with white walls.
They can be, if you hide the strip and set it to a warm white. Coloured light is fun for a party but rarely feels calm.
Usually three: one task light, one floor or table lamp for the room, and one small accent light. Three soft sources beat one bright one.
