A bedroom asks more of its lighting than any other room. It has to be bright enough to get dressed by in the morning, soft enough to read by at night, and warm enough that switching it on at 11 pm doesn't feel like an alarm. Getting it right comes down to three things: the colour of the light, how many sources you layer, and whether you can dim them.
What is the best LED light colour for a bedroom?
Warm white at 2700K is the best all-round LED light colour for a bedroom. For bedside lamps and late evening, go warmer, to an extra warm 2200K, which gives a soft golden glow close to candlelight. Keep cool white (4000K and above) out of the bedroom at night, and put your main lights on a dimmer, ideally with dim-to-warm bulbs that turn more golden as they dim.
Colour temperature is measured in Kelvin (K). The lower the number, the warmer and more golden the light; the higher the number, the whiter and bluer it gets. Warm light reads as evening and calm, while cool light reads as daytime and alertness. For how this plays out across the rest of the house, see our guide to warm white vs cool white LED lights.
What colour light is best for sleep?
The warmer the light, the less blue it contains, and blue is the part of the spectrum most linked to keeping you alert. We had our own range independently tested to measure how much blue light each colour temperature gives off.
| Colour temperature | Blue light (share of visible output) | Best bedroom use |
|---|---|---|
| 1800K (Sunset Dim, fully dimmed) | 0.6 to 0.7% | Last thing at night |
| 2200K (Extra Warm) | 1.4 to 1.5% | Bedside lamps, wall lights, evening |
| 2700K (warm white) | 2.0 to 2.5% | Main ceiling light, all-round use |
| 3000K (warm white) | 2.1 to 2.7% | Main light, if you prefer a slightly crisper look |
| 4000K (cool white) | 4.4% | Not recommended in a bedroom at night |

Dropping from 4000K to 2200K cuts the blue share by about two-thirds, and a Sunset Dim spotlight turned right down cuts it by around 85%. That matters because blue-rich light in the evening is associated with suppressed melatonin, the hormone that helps regulate sleep, while light from the amber and red end of the spectrum has much less effect. Our article on what blue light is and how colour temperature affects it sets out the full test results and the research behind them.
Red light is the extreme version of this, and some people use a red night light for exactly that reason. It's hard to do much else by, though. A 2200K extra-warm bulb, or dim-to-warm spotlights set low, gets you most of the benefit while still giving a flattering light you can read by. For more on timing light around sleep, see our guide to circadian lighting for sleep.
Colour rendering is a separate question. CRI (colour rendering index) measures how accurately a light shows colours compared with natural light, and it's different again from "full spectrum". A high-CRI bulb keeps skin tones, timber and linen looking natural, which is worth having in the room you dress in, but it doesn't tell you how much blue a bulb emits. Colour temperature does. Our guide to what CRI is explains the difference.
Layer your bedroom lighting
Most bedrooms are lit by one ceiling light, which is the main reason they feel flat. Designers build a bedroom from three layers.
Ambient light fills the room: a pendant, a ceiling fitting, or downlights (recessed spotlights). It needs to be bright enough for getting dressed and dimmable for the evening.
Task light is focused where you need it, usually for reading in bed or at a dressing table. Bedside lamps and wall lights do this best.
Accent light picks out a feature, such as artwork above the bed, a textured wall or a headboard. On its own, it also makes a soft, low evening option.
With all three in place, you choose the mix that suits the moment, instead of living with one light that's either too bright or off.
8 bedroom lighting ideas
1. Bedroom wall lights either side of the bed
A pair of wall lights clears the bedside tables and puts light right where you read. Position them slightly to the side of your head and a little above shoulder height when you're sitting up, so the light falls on the page rather than in your eyes. The Node wall sconce has an open E27 holder, so the bulb is your choice, and it comes in matte black, matte white and brass. Wall lights are hardwired, so they need to be installed by a qualified electrician.
2. A pendant instead of a bedside lamp
A pendant hung low beside the bed looks considered and frees up the bedside table completely. As a rule of thumb, hang it so the bulb sits around eye level when you're sitting up in bed. The Monad Single Drop works well here with an extra warm 2200K bulb.
3. Downlights that warm as they dim
Most LEDs stay the same colour as they dim, so a dimmed room can look grey rather than cosy. Sunset Dim GU10 and Sunset Dim MR16 behave the way halogens used to: a 2700K warm white at full brightness, sliding to an 1800K candlelight glow as you dim. If your bedroom already has GU10 or MR16 downlights or spotlights, swapping the bulbs is the simplest upgrade you can make.
4. Exposed filament bulbs by the bed
When a bulb is on show, in a sconce, a pendant or a glass lamp, you'll look at it as much as you'll use it. A clear filament bulb at 2200K gives a warm, low-glare glow that suits a bedside far better than a bright white bulb. The 4.2W Edison ST64 in Extra Warm has the classic squirrel-cage filament and pairs naturally with the Node.
5. Wash the headboard wall with light
A spotlight angled down the wall behind the bed casts a soft, hotel-like glow and brings out the texture of panelling, plaster, or timber. An adjustable-beam spotlight such as FlexBeam GU10 lets you widen or narrow the light so it grazes the wall rather than landing on the pillows. For more on how hotels use this effect, see ambient lighting for hotel bedrooms.
6. Keep a night-time setting
Set aside one light, or one dimmer position, for after dark only: a bedside lamp with a 2200K bulb, or Sunset Dim spotlights turned right down. It becomes a cue to wind down, and getting up in the night no longer means full brightness.
7. Put every circuit on a dimmer
A dimmer turns one light into several, and no other single upgrade does more for a bedroom. Most dimmable LED bulbs work with most incandescent and LED dimmers, but trailing-edge dimmers designed for LEDs give the smoothest result. Browse our LED dimmer switches, and have them fitted by a qualified electrician.
8. Match the bulb to the fitting
Inside a fabric shade, a frosted bulb is all you need, because the shade softens it. An exposed bulb should be chosen for looks as well as light. Candle bulbs suit small chandeliers and wall lights; our candle LED bulb guide covers the shapes and bases.
How do you choose bedroom LED lights and bulbs?
Brightness: go by lumens, not watts. For a main ceiling light in an average bedroom, the equivalent of an old 60W bulb works well; our 6.5W GLS in Extra Warm gives around 700 lumens. For bedside lamps and wall lights, aim lower, at around 400 to 500 lumens, roughly an old 40W bulb. The 4W Fancy Round in Extra Warm (400 lumens, frosted) suits shaded lamps, and the 4.2W Edison ST64 (470 lumens, clear) suits exposed bulbs. Our explainer on lumens, Kelvin and watts goes into more detail.
Colour temperature: 2700K for the main light, 2200K for bedside and evening.
Dimmability: choose dimmable bulbs for anything on a dimmer, as non-dimmable bulbs can flicker or buzz.
Base type: check your fitting before you buy. E27 (large screw) and B22 (bayonet) are the usual bases for ceiling lights and lamps; E14 (small screw) suits many wall lights and small lamps; and GU10 or MR16 are for downlights and spotlights.
Colour accuracy: choose a high CRI, so skin tones, timber and fabrics look natural.

Frequently asked questions
How bright should bedroom lighting be?
Bright enough for the job, and no brighter. A main light of around 700 lumens suits most bedrooms, while 400 to 500 lumens is plenty for bedside reading. A dimmer lets one fitting cover both.
Is 3000K or 4000K better for a bedroom?
3000K is the better choice. It's still a warm white, so the room stays relaxed. 4000K is a cool white that feels like daytime, which suits kitchens, laundries and workspaces better than a room you sleep in.
Is red or yellow light better for sleep?
Red light has the least effect on melatonin, so it makes a good dim night light, but it's not practical for reading or moving around. A golden 2200K bulb is the sensible compromise: low in blue, yet natural enough to use.
Do LED lights make a bedroom warmer?
Not noticeably. LEDs convert far more of their energy into light than incandescent bulbs, so they emit much less heat. A 6.5W LED replacing a 60W incandescent uses a fraction of the energy and runs much cooler.
Is it safe to sleep with LED lights on?
Good-quality LED bulbs run cool and draw very little power, so leaving one on is safe. For sleep quality, though, darkness is best. If you prefer some light, keep it as warm and dim as possible, such as a 2200K lamp or dim-to-warm spotlights turned right down.
What bulb should I use in a bedside lamp?
A dimmable, extra-warm 2200K bulb of around 400 to 500 lumens. That's enough to read by without lighting the whole room, and it won't feel harsh last thing at night.
