Choosing LED lamps: a practical guide to type, light and controls

Choosing a new lamp might seem straightforward, but there’s a wide range of LED lamps to choose from. A floor lamp, ceiling light or table lamp may look just right in a product photo, but the brightness, controls or dimensions might disappoint once it’s at home. Terms such as “energy-efficient”, “smart” and “dimmable” don’t always tell the whole story either.

Pay particular attention to these three common pitfalls:

  • Dimmable doesn’t always mean compatible with every dimmer. Some lamps only work with the supplied remote control or touch controls. An external wall dimmer may not be suitable.
  • A colour temperature range doesn’t tell you how much light a lamp gives off. 2700K produces warm white light and 6500K cool white light, but lumens are a better guide to practical brightness.
  • It’s easy to underestimate dimensions. An LED floor lamp around 180 cm tall needs a stable base and must fit beside your sofa, cupboard or desk. Check the cable length and where your power socket is, too.

Which specifications matter?

1. Lumens, wattage and room size

Lumens indicate how much light a lamp produces, according to its product specifications. Wattage tells you how much electricity it uses. A higher-wattage lamp isn’t automatically brighter, so check both figures.

A compact LED table lamp with 210 lumens may be enough for a bedside table or mood lighting. For general lighting in a living room, a higher lumen output or several light sources may be more suitable. An LED ceiling light will generally spread light more evenly around a room than a single lamp in the corner.

Check the energy rating, too, if one is listed. An integrated LED module can be efficient, but make sure it’s replaceable. Several models in this guide have an integrated, non-replaceable light source. When it reaches the end of its life, you’ll generally need to replace the whole lamp.

2. Colour temperature and colour rendering

Colour temperature is measured in kelvin (K):

  • 2700K–3000K: warm white, ideal for relaxing and evening use.
  • 4000K: a more neutral white, suitable for reading, working and general lighting.
  • 6000K–6500K: cool white, useful when you want brighter, more functional light.

An LED lamp with adjustable colour temperature is practical if a room serves several purposes. Check the CRI or Ra value, too. This indicates how accurately colours are rendered. For example, the Xiaomi LED Desk Lamp 2 lists Ra95. This is a product specification you can check, although your experience will also depend on where you place the lamp and the surrounding conditions.

3. Controls, stability and safety

A dimmable LED lamp can be useful in a living room or bedroom. Check how the dimming works: by touch control, remote control, wall switch or, in some cases, a voice assistant. An LED lamp with a remote control is handy when it’s out of reach.

A floor lamp needs a heavy base and a stable surface. Arrange cables to avoid creating a trip hazard. Products with an IP20 rating are designed for dry indoor spaces and shouldn’t be used in damp areas. When fitting a ceiling light, check that the surface can support the fitting. Electrical installation must comply with local regulations.

Frequently asked questions about LED lamps

How many lumens do I need for a living room?

It depends on the size of the room, the colour of the walls and the number of light sources. Choose a lamp with enough lumens for general lighting, and consider adding a floor lamp or table lamp for a reading area. Don’t look at wattage alone.

How long does an LED lamp last?

Lifespan varies by model and conditions of use. Some product listings state a lifespan of 20,000 hours, for example. With integrated LED lighting, the light source is often non-replaceable. Before you buy, check whether the fitting uses a replaceable light source, and keep the product information.

Do LED lamps use less electricity?

LED lighting generally uses less power than many older lighting technologies to produce a similar amount of light. Calculate running costs using: wattage ÷ 1000 × hours of use × electricity price. For example, a 10W lamp used for five hours a day consumes 0.05 kWh per day. The actual cost depends on your energy tariff.
