Lighting does more than anything else to make a corner feel cosy and to make it comfortable to read in. Get it right and you’ll want to sit there every evening; get it wrong and you’ll be squinting or dazzled. This guide explains the jargon on bulb boxes and how to place a lamp so the light lands on the page, not in your eyes.
Layer your light
Cosy rooms rarely rely on a single ceiling light. Aim for two or three sources:
- Ambient light, such as the main light (ideally on a dimmer) or a large lamp, for general brightness.
- Task light, such as a reading lamp aimed at the page. This is the one that matters most.
- Accent light, such as fairy lights, a small lamp on a shelf or flameless candles, for atmosphere.
In the evening, try turning the ceiling light off and using just a task light plus one softer accent light. The room feels warmer straight away.
Colour temperature: what “warm white” means
Bulbs are labelled with a colour temperature in kelvin (K). The lower the number, the warmer (more yellow-orange) the light:
| Label | Roughly | Feels like |
|---|---|---|
| Extra warm / candlelight | about 2200K or lower | Very golden, like candlelight. Atmospheric, but can feel dim for reading. |
| Warm white | about 2700K | Similar to an old-style incandescent bulb. The usual choice for cosy living rooms and bedrooms. |
| Cool or neutral white | about 4000K | Crisper and brighter-looking. Common in kitchens and offices. |
| Daylight | about 5000K–6500K | Bluish-white. Good for detailed tasks; can feel clinical in the evening. |
For a cosy reading corner, warm white (around 2700K) is a sensible default. If you also read or do crafts during the day, a tunable white or smart bulb lets you choose a crisper light in the daytime and a warmer one in the evening.
Brightness: look at lumens, not watts
With LED bulbs, watts tell you how much energy the bulb uses, and lumens (lm) tell you how bright it is. Compare lumens when choosing. Many boxes also show an “equivalent” old-style wattage to help you compare.
For a reading lamp, a brighter bulb on a dimmer is more flexible than a dim one, since you can turn it down for atmosphere and up for small print. People generally need more light to read comfortably as they get older, so if you’re buying for an older relative, err on the brighter side.
Colour rendering (CRI)
Some boxes list a CRI (colour rendering index) figure. It describes how naturally a light shows colours, on a scale up to 100. A CRI of 90 or above makes book covers, skin tones and fabrics look more natural. It’s a nice extra, but less important than colour temperature and brightness.
Check the fitting before you buy
UK lamps use several bulb caps. Check the old bulb or the lamp’s label:
- B22, standard bayonet: very common in UK ceiling lights and lamps.
- E27, standard Edison screw: common in lamps, especially imported ones.
- E14, small Edison screw: often used in smaller lamps and candle bulbs.
- B15, small bayonet: found in some small lamps and fittings.
- GU10, two-pin push-and-twist: used in spotlights.
Also check the lamp’s maximum wattage, printed on the fitting or label, and don’t exceed it.
Dimmers and smart bulbs
- If your light is on a dimmer switch, buy bulbs marked dimmable and check they’re compatible with the dimmer. Some older dimmer switches can make LED bulbs flicker or buzz.
- Smart bulbs let you dim and change colour temperature from an app or voice assistant without changing the switch. Check whether a bulb needs a separate hub and which app or system it works with.
- Plug-in lamp dimmers are a simple renter-friendly way to dim an ordinary lamp.
Where to put the lamp
- Over your shoulder: position a floor lamp beside and slightly behind your chair so light falls onto the page. Many people find it comfortable to have the light coming from the side opposite their writing hand, so their hand doesn’t cast a shadow when turning pages or making notes.
- Shade at the right height: with a shaded floor or table lamp, you shouldn’t be able to see the bare bulb from your seat. If you can, the shade is too high or too shallow, and you’ll get glare.
- Adjustable is easiest: arc lamps, swing-arm lamps and lamps with a tilting head let you aim light exactly where you need it.
- Avoid screen glare: if you read on a tablet or e-reader, angle the light so it doesn’t reflect off the screen.
- Mind the cables: run cables behind furniture and don’t trail them across walkways.
Cosy extras, safely
- Flameless LED candles give a candlelit glow without a naked flame, which is useful near books, curtains, pets and children.
- If you do use real candles, never leave them unattended, keep them away from anything that can catch fire (books included), and put them out before you fall asleep.
- Fairy lights on a shelf add soft accent light. Battery or USB-powered sets avoid extra plugs.
Quick checklist
- Warm white (around 2700K), or tunable if you read in the daytime too
- Bright enough in lumens, ideally on a dimmer
- Right cap (B22, E27, E14…) and within the lamp’s maximum wattage
- “Dimmable” if it’s going on a dimmer switch
- Lamp placed beside or behind you, with no bare bulb in view
- Cables tidy and out of walkways
