Buying a table lamp: a guide to design, lighting and battery power

A table lamp needs to do more than look good. It should suit the space available, the light you need and how you plan to use it every day. Whether you’re looking for an LED table lamp for your desk, a bedside lamp for the bedroom, a reading lamp for a cosy nook or a decorative table lamp for the living room, different styles are designed for different purposes.

However, buying the wrong lamp can lead to unnecessary costs. Watch out for these three common pitfalls:

  • Choosing design over function: An eye-catching shape tells you little about brightness, light distribution or ease of use.
  • Unclear power supply details: ‘Cordless’ could mean the lamp has a built-in battery, but sometimes it simply has a short cable or the cable isn’t included.
  • Missing details about the light source: Lamps with an E14 fitting often don’t include a bulb. With integrated LEDs, the light source usually can’t be replaced.

That’s why it’s best to start with the technical details and where you plan to use the lamp.

What to check before you buy

1. Power supply: mains, USB or battery

For a permanent workspace, a mains-powered table lamp with a cable that’s long enough is a good choice. For example, the Brilliant Mushroom Design Table Lamp has a 150 cm cable, a Europlug and an E14 fitting. The product details state that the bulb isn’t included. This means you can choose a suitable LED or candle-shaped bulb, but you’ll need to buy it separately.

A battery-powered table lamp or cordless table lamp is more flexible for use on a balcony, dining table, in the bedroom or when camping. Check the following:

  • Battery capacity and stated run time
  • Charging port, such as USB-C
  • Charging time
  • Whether the lamp can be used while it’s charging
  • Safety guidance for using the lithium battery

The Nightstand Lamp Cordless Table Lamp has a built-in 1800-mAh battery, a USB-C charging port and a stated run time of up to six hours. According to the product description, it takes around three hours to charge fully.

2. Brightness, colour temperature and dimming

A dimmable table lamp is more versatile than a model with just one brightness setting. Focused lighting is useful for reading or working, while a lower light level is often enough for a bedside lamp.

Look out for these details:

  • Lumens: Indicate the amount of light. A higher lumen rating doesn’t automatically mean the light will be distributed more pleasantly.
  • Kelvin: Indicates the colour temperature. Lower values usually look warmer, while higher values appear more neutral or cooler.
  • Dimming options: Two brightness levels, stepless dimming and preset scenes all offer different ways to adjust the light.
  • Light distribution: A lampshade or diffuser can spread light more widely and evenly.

Joybuy’s battery-powered table lamp offers a choice of colour temperatures from 3000 to 6500 K and stepless brightness adjustment from 0 to 100 per cent using touch controls. The DEWENWILS reading lamp, by contrast, has a colour temperature of 3000 K, two brightness settings and a stated light output of 16 lm. It’s better suited to lighting the page of a book up close than evenly lighting an entire desk.

3. Size, material and where you’ll use it

Measure the space available before you buy. A lamp that’s 27 to 31 cm tall may take up a fair amount of room on a bedside table, while a compact light might be a better fit for a shelf.

Other points to consider:

  • Stability and base size
  • Heat produced by the bulb
  • IP rating, such as IP20 for dry indoor spaces
  • Material and how easy it is to clean
  • How easy the switch is to reach
  • A safe distance from textiles and other heat-sensitive items

When choosing a lamp for a child’s bedroom, don’t focus on design alone. Check the age guidance, stability, cable routing and the manufacturer’s safety information. You can also browse our range of desk lamps for children.

Frequently asked questions about table lamps

How many lumens should a table lamp have?

It depends on how you’ll use it. A small reading lamp lights a limited area, so it may not need a high light output. For a desk, the light should be evenly distributed. As well as checking the lumen rating, consider the beam angle and where you’ll position the lamp.

How long does the battery in a cordless table lamp last?

Run time depends on battery capacity, brightness and which features are switched on. Figures such as six, eight or up to 15 hours should therefore be treated as guidelines for the stated conditions. If you’ll use the lamp regularly, it’s worth checking that the USB-C port is easy to reach and the charging time is clearly stated.

Does an LED table lamp use a lot of electricity?

LED lights usually use little power when they’re on. A battery-powered table lamp also uses electricity when it’s charging. To compare models fairly, consider the stated wattage and how long you’ll use the lamp each day. If it has a replaceable bulb, check its energy efficiency label too.
