Buying lamps: how to choose lighting that suits your space and needs

Choosing a new lamp may seem straightforward, but a good-looking photo says little about how it will perform day to day. For example, a desk lamp may not provide enough light for working from home, while a bedside lamp can be too bright or too cool-toned for the bedroom. The right fitting, positioning and energy consumption also determine whether your purchase remains practical.

When buying lamps, watch out for these common pitfalls:

• Looking only at wattage: wattage mainly indicates energy consumption, not the amount of light produced. Also check the number of lumens.
• Overlooking light colour: 2700 K generally produces warm white light, while 4000 K or higher looks cooler. Colour temperature has a major impact on the atmosphere.
• Not checking the fitting: an E27 LED bulb will not fit a light fitting designed for E14. Also check the lamp’s maximum wattage.
• Underestimating dimensions: a large desk lamp can get in the way on a small desk. With a clip-on lamp, you should also check that the clamp fits the edge of your table or shelf.
• Treating product claims as guarantees: a brand may mention a long lifespan or lower energy consumption. Treat this as information from the product description or, where stated, as a claim based on the brand’s own research. Always check the technical specifications and warranty conditions.

Which specifications matter when choosing lamps?

1. Light output and colour temperature

The amount of light is measured in lumens (lm). A bedside lamp usually needs far fewer lumens than a desk lamp for reading or working. For a workspace, high light output is not the only consideration; it should also be possible to direct the beam effectively.

The colour temperature in Kelvin (K) helps you choose the right atmosphere:

• 2700 K: warm white, suitable for living rooms, bedrooms and mood lighting.
• 3000–4000 K: more neutral light for a desk, kitchen or hallway.
• 6500 K: cool white light; check that this suits the room and your preference.

A dimmable lamp can be useful when you use the same light fitting at different times. However, check whether the dimming function is built into the lamp or whether you need a suitable dimmer and light source.

2. Fitting, light source and energy consumption

Check the fitting before buying. An E27 LED bulb has a large screw fitting and is often used in floor lamps, table lamps and pendant lights. E14 is smaller and is commonly found in compact fittings and wall lights.

Pay attention to the difference between a lamp with:

• Replaceable light source: you can fit a different LED bulb later, for example with another colour temperature or a dimming function.
• Integrated LED: the light source is built in. This creates a compact design, but replacement is generally not intended according to the product information.

Lower wattage does not automatically mean less light. For example, a Philips UltraEfficient LED bulb is listed in the product information as 2.3 W, 485 lm, 2700 K and energy label A. The specifications also state that this version is not dimmable. Another Philips LED bulb in the range is listed as 13 W and 1521 lm. Always compare lumens, wattage, fitting and energy label together.

3. Positioning, safety and protection

A lamp with a suitable IP rating is required for a damp area. Products with IP20 are designed for dry indoor spaces and must be kept away from water and moisture. This applies, for example, to many table lamps, desk lamps and wall lights.

Place a lamp on a stable surface and keep cables out of walkways. With a clip-on lamp, make sure the clamp is firmly secured. Switch off the power before replacing a separate light source, and never use a lamp with a damaged cable or plug.

Recommended lamps by user profile

Suitable for: Budget-conscious beginners

Brilliant Desk Lamp, 70 cm Height, Adjustable Head and Joints, E27, 40 W

Why it suits this profile: This metal clip-on lamp uses a replaceable E27 light source. You can choose an LED bulb up to the maximum 40 W yourself and adjust the colour temperature later.

How this product avoids the pitfall

The adjustable head and joints help overcome the limitations of a fixed beam. However, check the table thickness beforehand and only use the lamp indoors, in a dry area with an IP20 rating.

Key benefit & highlights

E27 fitting, adjustable head and joints, integrated push button and approximately 1.6 metres of cable.

Suitable for: Buyers seeking premium quality

Philips UltraEfficient LED Bulb, E27, Warm White Light, 6-pack

Why it suits this profile: Handy for anyone who wants to fit several light fittings with the same large socket, create warm lighting and compare consumption per light point.

How this product avoids the pitfall

The product details specify the fitting, light output, colour temperature and energy label. This allows you to check your choice rather than relying solely on the word ‘efficient’.

Key benefit & highlights

E27 fitting, 2700 K warm white light, energy label A according to the product information and a six-pack. Not dimmable.

Suitable for: Specific uses & intensive users

Brilliant Led Desk Lamp With Warm White Light, Swiveling Table Lamp

Why it suits this profile: For a dedicated work or reading area, this table lamp provides integrated LED lighting with 650 lm, plus an adjustable arm and lamp head.

How this product avoids the pitfall

The light output and colour temperature are clearly specified: 650 lm and 2700 K. Bear in mind that, according to the product information, the integrated LED light source is not replaceable.

Key benefit & highlights

8.5 W integrated LED, 650 lm, warm white 2700 K light, height-adjustable design and swivel lamp head.

Xiaomi Flexible Rechargeable Lamp - 3.5W, White

Why it suits this profile: This rechargeable lamp is ideal when you want to move your lighting without needing a socket every time, for example on a desk, shelf or bedside table.

How this product avoids the pitfall

The flexible, cordless design means that a cable does not dictate where you can place it. However, check the 5 V charging voltage before buying and bear in mind that the lithium-ion polymer battery needs to be recharged.

Key benefit & highlights

3.5 W power, 2000 mAh battery and flexible use without a direct connection to a socket.

Practical room-by-room guide

• Living room: choose warm lighting of around 2700–3000 K. A wall light or table lamp can illuminate a specific corner without making the entire room bright.
• Workspace: consider lumens, adjustability and reflections on the screen. A desk lamp with a swivel head or a clip-on lamp saves space.
• Bedroom: a bedside lamp with warm light is often more practical than a bright ceiling light. A sensor light can be useful in the hallway or beside the bed.
• Children’s room: check the material information, stability, charging method and controls. A children’s lamp with a timer and limited brightness settings can be practical, but keep rechargeable products out of reach when cables or small parts could pose a risk.
• Hallway: a compact LED or wall light works well when the fitting takes up little space. With a wall light, check that the mounting and wiring are suitable for your situation.

Frequently asked questions about lamps

Which lamp is suitable for a desk?

Look at lumens, adjustability and the space available. A desk lamp with a swivel head directs light onto paper or the keyboard. A clip-on lamp frees up space on the work surface, but the clamp must fit securely onto the edge of the desk.

How much does an LED bulb cost to run?

This depends on the wattage, number of hours used and your energy tariff. Use this simple calculation: wattage ÷ 1000 × number of hours used × electricity price. An LED bulb with lower wattage may therefore use less electricity, but always compare the light output in lumens as well.

Can I dim every LED bulb?

No. Check whether the product page or packaging states that the LED bulb is dimmable. With a non-dimmable E27 LED bulb, a standard dimmer may cause flickering or poor light control. With integrated LED lighting, the dimming function must be specifically built into the fitting.
