What Kelvin value should I choose for home lighting?

For living areas and bedrooms, warm white between 2700 and 3000 Kelvin is ideal. For kitchens and home offices, 4000 Kelvin neutral white is more suitable. For bathroom vanity areas, 3500 to 4000 Kelvin provides the most natural colour rendering.

How many watts do I need?

With LED technology, wattage no longer determines brightness — lumens do. For a living room, 300 to 500 lumen downlights work well; for a bedroom, 200 to 300 lumens is sufficient; and for a reading nook, a 500 to 800 lumen task light is recommended.

Is a pendant light or downlighting better?

Using both together gives the most versatile result. Ceiling downlights provide general illumination, a pendant creates a focal point and decorative impact, and a floor lamp adds soft ambient light. Layered lighting delivers the most attractive and comfortable outcome.

How much should I budget for lighting?

Basic lighting for a standard room costs between £100 and £300. A complete living room lighting scheme (pendant, downlights, floor lamp) ranges from £300 to £1,500. Choosing LED fittings provides long-term savings on energy bills.

Lighting Selection Guide: Room-by-Room Recommendations 2026

How to Choose Home Lighting

The best approach to lighting selection is to consider the room's function and match the colour temperature (Kelvin), brightness (lumens) and fitting type accordingly. In multi-purpose spaces like the living room, layered lighting works best; in working areas like the kitchen, strong neutral light is essential; and in bedrooms, warm, dimmable light sources are the way to go.

Lighting is one of the most powerful and cost-effective ways to transform the atmosphere of any room. The right fitting and bulb choice delivers both comfort and energy savings. In this guide you will find recommended lighting solutions for every room, along with current 2026 price information.

Colour Temperature and Kelvin Values

The colour temperature (Kelvin value) of a bulb directly sets the mood of a space:

Kelvin Value	Light Colour	Suitable Areas
2,700 K	Warm White	Living room, bedroom, reading nook
3,000 K	Soft White	Lounge, hallway, children's room
3,500 K	Neutral White	Bathroom, dressing room
4,000 K	Cool White	Kitchen, home office, study
5,000 - 6,500 K	Daylight	Workshop, vanity mirror, office

Homes fitted with a single bulb colour throughout often feel overly clinical in some rooms and too dim in others. Choosing the right Kelvin value for each room transforms the feel of a space without spending anything on new decor.

Living Room Lighting: Layered Light

The living room hosts more different activities than any other room, so a single light source is never enough:

General lighting: Ceiling downlights or a pendant illuminate the whole space. Choose warm white (2,700 to 3,000 K).
Task lighting: A floor lamp or wall light beside a reading chair. Aim for at least 500 lumens.
Accent lighting: Narrow-beam spotlights or picture lights to highlight artwork, shelving or decorative objects.
Ambient light: Low-wattage decorative bulbs or LED strips create a warm, relaxed atmosphere.

Planning your lighting scheme before you begin redecorating makes it far easier to choose the right fittings. Our guide to living room decor costs includes detailed budget-planning advice.

Kitchen Lighting: Function First

The kitchen is a working environment — cutting, cooking and cleaning all demand strong, shadow-free illumination:

Ceiling general lighting: 4,000 K neutral white, using LED panels or grid-pattern downlights. Aim for even coverage across all worktop surfaces.
Under-cabinet lighting: LED strips or linear fittings mounted beneath wall units light the worktop without shadows.
Island or breakfast bar lighting: Pendant fittings above an island provide both functional light and a decorative focal point.

Bedroom Lighting: Comfort and Sleep Quality

Bedroom lighting directly affects sleep quality and the overall sense of calm:

General light: Warm white (2,700 K) ceiling downlights or a pendant. Adding a dimmer switch makes the room significantly more comfortable.
Reading lamp: A bedside table lamp or wall-mounted reading light provides focused local illumination.
Night light: A low-lumen night lamp or dimmed LED offers gentle orientation without disturbing sleep.

Blue-toned light (above 5,000 K) suppresses the sleep hormone melatonin and should be avoided in bedrooms entirely.

Bathroom Lighting: Visibility and Safety

In the bathroom, both clear visibility and electrical safety in a wet environment are essential:

Fitting Type	Kelvin	Use
Vanity Mirror Light	3,500 - 4,000 K	Around the mirror
Ceiling Downlight	4,000 K	General illumination
Shower Spotlight	4,000 K	IP65 rating required
Night Light	2,700 K	Night-time orientation

All bathroom fittings must have an IP44 or higher rating for protection against moisture and splashing. Fittings installed inside the shower zone require IP65 as a minimum.
