Buying a Table Lamp: What to Consider for Design, Lighting and Operation

A table lamp should do more than simply look good on a side table. The bedroom calls for a pleasant bedside lamp, the workspace needs a functional desk lamp, while the living room often benefits from a decorative table light with a warm glow. However, if you choose solely based on design or advertising claims, it is easy to overlook important details.

Typical purchasing problems arise from three common pitfalls:

• Unclear information about the light source: An LED table lamp with a permanently integrated bulb cannot necessarily be fitted with a new bulb if it develops a fault.
• No dimming function despite atmospheric product images: “Atmospheric lighting” does not automatically mean that the brightness can be adjusted.
• Unsuitable power supply and dimensions: A cordless table lamp needs regular charging. A mains-powered lamp, on the other hand, requires an accessible socket and sufficient cable length.

The most important buying criteria for a table lamp

1. Check the fitting, bulb and maximum wattage

With a table lamp with an E27 fitting or E14 fitting, buyers can usually choose the bulb separately. The key points are:

• Fitting type: E27 is larger and suitable for many standard LED bulbs. E14 is more compact.
• Maximum wattage: The stated “max. 25 W”, “max. 40 W” or “max. 60 W” must not be exceeded.
• Contents: Several models do not include a bulb. This should be factored in before purchase.
• Integrated LED: With permanently integrated LEDs, the light source cannot be replaced easily.

An LED table lamp can be economical to run, but wattage alone does not indicate brightness. The figure given in lumens is more informative when assessing light output. A small accent light with 30 lumens serves a different purpose from a desk lamp designed to illuminate the work surface directly.

2. Choose the right colour temperature and dimmability for the room

Warm white light is often preferred in bedrooms and living rooms. It creates a less technical feel than a high colour temperature. Wherever possible, the product information should state a specific Kelvin value.

The information about the dimming function deserves particular attention. There are different ways to operate a lamp:

• Touch dimmer: Brightness is changed by touching the lamp base or cable switch.
• Stepped dimming: For example, four brightness levels are available.
• On/off switch: The lamp has no brightness control, even if it is described as an ambient light.

With a dimmable table lamp, you should also check whether the dimming function is already integrated or whether a compatible dimmable bulb is required.

3. Compare the dimensions, footprint and power supply

Before placing your order, compare the height, width and diameter with the space where the lamp will be used. A large light with a diameter of 30 cm can quickly become intrusive on a small bedside table. Compact models are more suitable for narrow shelves or consoles.

There are three practical power supply options:

1. Mains operation: constant use, but dependent on a nearby socket.
2. USB or USB-C operation: suitable for power adapters, computers or power banks; check the connection type and cable length.
3. Battery operation: flexible positioning without a cable, but requires charging and offers a limited lighting duration.

The IP rating is also relevant. IP20 indicates use in dry indoor areas. A lamp with this rating is not intended for damp conditions or outdoor use. Even if a product description lists many types of room, the technical IP rating should take priority.

Frequently asked questions about table lamps

Which table lamp is suitable for a bedside table?

For a bedside table, compact dimensions, an easily accessible switch and warm white light are practical choices. A bedside lamp with touch control can be convenient. With a cordless model, the battery life should suit your usage routine. You should also check the lamp’s stability and the position of the shade before buying.

How much electricity does an LED table lamp use?

Consumption depends on the wattage and the number of hours the lamp is used each day. A 3 W lamp used for five hours a day consumes around 15 Wh per day. To calculate the running costs, multiply this consumption by your electricity price. The actual cost can therefore only be calculated using the wattage, usage time and tariff.

How long does a table lamp last?

With a lamp featuring a replaceable E27 or E14 fitting, the lamp’s lifespan depends on the bulb used. With an integrated LED, the light source is permanently built in and cannot be replaced easily. Switches, cables, batteries and proper use also affect the lamp’s practical service life. Models designed for dry indoor areas should not be used in damp conditions.
