How to Choose a Cordless Table Lamp for Your Home

A table beside your sofa can be the perfect place for a little extra light, even when the nearest power socket is behind a bookcase. With a cordless table lamp you can place the light exactly where you need it and move it later to another part of the home.

Some lamps give a soft glow over dinner. Others put useful light on a page for reading. Battery life, the shape of the shade and the position of the switch all affect how well the lamp fits your routine.

The short answer

Choose for the main job first, then check size, light output and charging. Warm white is a useful starting preference for relaxed evening spaces. For reading, look for light on the page. Check outdoor suitability separately: a battery does not make a lamp weatherproof.

1. Decide what you want the light to do

For a dining table, consider a low, shaded lamp that lights the tabletop without blocking your view of the person opposite. Measure the lamp’s total height as well as its widest point to ensure it will fit on your table, even with items such as flowers, glasses and serving dishes placed upon it. Remember to leave space to place a plate on either side of the lamp.

A lamp on a side table close to a bed is primarily used in different ways than a lamp on a dining table. For reading, you need enough useful light on the page, even if you only read for a few minutes. A decorative glow alone may not be enough. You also have to consider where the light will come from and whether you can easily adjust the lamp.

For a side table beside the sofa, sit down and look toward the planned lamp position. An exposed LED may feel harsh at eye level even if the lamp looks good from above.

Look through Sedelli's table lamps with your intended location in mind. Browse them as if you were looking for a single lamp to use in one place.

2. Measure the whole lamp, not just the base

A base can fit comfortably while the shade overhangs the edge. Measure the widest part of the lamp and its full height. Compare its width with the usable tabletop, then check its height against seated sightlines.

Cut a paper circle to the lamp's widest diameter and put it on the table beside the things you keep there. Is there room for a book and glass? Would someone brush against the lamp walking past?

Be mindful that even a cordless lamp can be knocked over. Look for a lamp that will sit stably on your table, and make sure you place it on a level surface and follow the maker's instructions for use.

3. Separate brightness from light color

Lumens measure light output; watts measure power use. Compare lumens where the specification provides them; higher wattage alone does not tell you which LED lamp gives more useful light.

Color temperature, measured in kelvins (K), describes the appearance of white light. Around 2700K to 3000K generally looks warm. Around 4000K looks more neutral or cooler by comparison, while 5000K to 6500K tends toward daylight-like white. Names such as 'soft' and 'cool' vary between sellers. The Kelvin number makes comparison easier.

For evening dining, try warm white. For reading, warm or neutral light may suit you, depending on the room and your preference. A higher Kelvin number does not automatically mean more brightness.

Dimming changes brightness. Adjustable color temperature changes how warm or cool the white light looks. These are separate features, so check the controls if you want both.

4. Read the battery details carefully

An 'up to' runtime needs context. A lamp may last much longer at low brightness than at full output. Check which setting was used for the quoted runtime, and look for a figure that matches how you plan to use it.

It’s also important to know the runtime on different settings. 2 hours might be plenty to last over dinner, for example, but not enough to last through hours of reading.

Check charging time as well as runtime. Does the lamp use a cable, charging base or removable battery? Find out whether the required cable and power adapter are included or sold separately.

Follow the manufacturer's charging instructions for that lamp. These often differ from the lamp you already have and can include things like whether you can leave the lamp switched on whilst charging and whether the charger supplied with the lamp is compatible with your local power sockets. Don’t assume a charger with a matching plug is suitable. Ask the seller if your questions aren’t answered in the listing.

5. Think about everyday controls

Touch controls can suit a bedside lamp if they are easy to find in the dark. A remote may help when the lamp sits across the room. Check which functions it operates and whether it needs a separate battery.

Check what happens when you switch the lamp back on. Some models remember the previous setting; others reset. Memory and timers are product-specific features, not standard functions of every rechargeable lamp.

Consider the weight and grip if you plan to move the lamp often. Sedelli's Ronalise Cordless Table Lamp has a loop handle. The Vanolire Rechargeable Table Lamp has a round metal body with a disc-shaped top. Look for pictures of the lamp from the side, to get a sense of its shape and how it will look. Compare each lamp's current specifications before choosing.

6. Check the location rating before taking it outside

'Cordless' describes the power supply, not protection against rain, splashes, humidity or dust.

For a patio, balcony or damp room, check the manufacturer's stated location suitability and relevant protection rating. Check the charging instructions too: the lamp's permitted location does not automatically apply to its charger.

If outdoor suitability is unclear, keep the lamp indoors until the seller confirms it. A lifestyle photo beside a pool or on a garden table is not a substitute for the actual use and storage instructions.

Your buying checklist

Before purchasing a cordless table lamp, you must be able to answer these questions:

• What is the main use of the cordless table lamp?
• Is it going to fit on the table and leave sufficient surface area for objects?
• What light output and color settings does the listing specify?
• What runtime is stated at the brightness I expect to use?
• How does it charge, and which charging accessories are included?
• Are the controls easy to reach?
• Does its location rating cover where I plan to put it?

Common questions

Can a cordless table lamp replace my main room light?

This would normally be used as an additional light source to supplement your existing lighting rather than be your sole source of light. As with any lighting it is necessary to consider the lamp’s output, the beam from the shade and how you intend to use the light in the room.

Are all cordless lamps rechargeable?

No, some cordless lamps use replaceable batteries whilst others have rechargeable batteries. Find out the details for your particular lamp model from the seller’s listing or from the seller themselves directly.

What if the listing does not give a runtime or brightness figure?

Make sure the retailer can confirm any missing information for you. Don’t try to make an estimate for runtime based on the size of a product, or the brightness of a lamp from a style shot. Ask.

Conclusion

Once the size and functions suit your routine, choose a finish and shape that you enjoy seeing in the room.
