Choosing lamps: A practical buying guide for every room

The right lighting should suit your room, how you use it and your personal interior style. But striking designs and impressive-sounding features don’t automatically make a lamp the right choice. If you choose based only on appearance or wattage, you could overlook important details.

Common pitfalls include:

  • Unclear brightness information: Wattage tells you how much electricity a lamp uses, not how much light it produces. For that, check the figure in lumens.
  • Dimmable doesn’t always mean the same thing: Some lights can only be adjusted in set increments, while others offer stepless dimming. With bulbs and lamps that have replaceable fittings, you’ll also need to make sure the dimmer and bulb are compatible.
  • The wrong location: A lamp with an IP20 rating is designed for dry indoor spaces. Bathrooms, balconies and sheltered outdoor areas have different requirements.
  • Built-in LED modules: With integrated LED lamps, the light source can’t be replaced separately. Make sure you’re aware of this before buying.

The key things to consider when buying a lamp

1. Brightness, colour temperature and colour rendering

Light output is measured in lumens (lm). For example, a 360 lm desk lamp is suitable for focused tasks over a limited area. For general living room lighting, it’s often useful to combine several light sources.

Colour temperature in kelvin (K) describes the effect of the light:

  • 2700–3000 K: warm white, ideal for living rooms and bedrooms
  • 4000 K: neutral white, often used in workspaces
  • 5000–6500 K: daylight white, useful for certain task areas

Dimmable lamps with adjustable colour temperature offer a flexible solution. The CRI or Ra value indicates how naturally colours appear under the light. The right choice will depend on your room and how you plan to use the lamp.

2. Energy use and design

When comparing LED lamps, consider their wattage alongside their light output in lumens. Energy efficiency classes on the EU energy label range from A to G. A low wattage alone isn’t enough to make a meaningful comparison.

For LEDs with built-in modules, it’s also worth checking:

  • the stated lifespan of the LED module
  • whether it can be replaced
  • the mains voltage and connection type
  • whether it’s operated by a switch, remote control or touch panel

Lamps with an E27 fitting offer more flexibility, as you can choose and replace the bulb separately. For decorative pendant lights and battery-powered lamps, check whether bulbs and batteries are included.

3. Dimensions, stability and protection

Before you buy, compare the height, base diameter, cable length and footprint with the space you have in mind. A slim floor lamp takes up little floor space, but it still needs to stand on a firm, level surface.

Night lights with light sensors can be handy in children’s bedrooms, hallways and by the bed. Check how they switch on and off, how bright they are and how much heat they generate. Mains electrical work should be carried out by a suitably qualified professional. Don’t use lamps in damp areas unless their protection rating is suitable.

Frequently asked questions about lamps

How many lumens do you need for a living room?

It depends on the size of the room, the ceiling height, the wall colours and the atmosphere you want to create. A combination of a ceiling light, floor lamp and table lamp is often more practical than relying on a single, very bright light source. For specific tasks such as reading, your lamp should light the seating or work area well without dazzling you.

How long do LED lamps last?

Manufacturers state the lifespan in operating hours. It can depend on factors such as heat dissipation, switching cycles and operating conditions. With integrated LEDs, bear in mind that the module may not be replaceable. With lamps that have an E27 fitting, you can replace the bulb separately.

Do dimmable lamps use less electricity?

Dimming often reduces energy use, but not necessarily in proportion to the drop in brightness. The product’s technical specifications are what matter. When choosing RGB floor lamps, reading lamps or office lighting, check the wattage, lumens and dimming technology.
