Choosing a Table Lamp: What Matters for Light, Design and Power Supply

A table lamp should do more than simply look good. It needs to suit its location, the desired lighting mood and the available power supply. Whether you are looking for an LED table lamp for your desk, a bedside lamp for the bedroom or a decorative table lamp for the living room, many poor purchases are the result of unclear product information and overlooked details.

Common pitfalls when buying a table lamp

1. Judging brightness solely by wattage

Wattage mainly describes energy consumption, not actual brightness. For comparisons, luminous flux in lumens is more meaningful. An LED table lamp with 400 lumens may be suitable for a bedside table, while a workplace may require stronger, more precisely directed lighting, depending on the task.

2. ‘Dimmable’ does not always mean continuously dimmable

With a dimmable table lamp, check whether it offers several preset brightness levels or continuous adjustment. The position of the controls also matters: a touch switch on the lamp base, a rotary knob or a control on the cable will suit different locations.

3. Confusing cordless use with unlimited run time

A cordless table lamp generally requires an integrated rechargeable battery or batteries. The stated run time depends on the brightness level. Figures given for the lowest brightness cannot be directly compared with run time at full power. With a rechargeable table lamp, the charging port, charging time and battery capacity are also important purchasing details.

Key parameters at a glance

Light colour and colour rendering

Light colour is measured in Kelvin:

  • 2,400 to 3,000 Kelvin: warm, inviting light for bedrooms, living rooms and decoration
  • 4,000 Kelvin: more neutral light for everyday use and desks
  • 5,000 Kelvin: cooler light for focused tasks, depending on your personal needs

A table lamp with warm white light is often around 3,000 Kelvin. The CRI or Ra value is relevant for colour rendering. An Ra value of 80 is specified for the Aigostar lamp. This value describes how naturally colours appear under the light; it is not a measure of brightness.

Power supply and operating time

A table lamp with a mains connection is suitable for a fixed location. It provides continuous light but requires a socket. A battery-powered table lamp or rechargeable model can be used flexibly on shelves, sideboards or terraces.

Look out for the following details:

  • Battery capacity in mAh
  • Charging port, such as USB-C
  • Charging time
  • Run time at each brightness level
  • Whether it is intended only for dry indoor areas or also for dry outdoor use

A stated protection rating such as IP54 should be considered in the relevant product context. It does not replace the manufacturer’s safety instructions and does not automatically mean that the lamp may be used outdoors permanently or in the rain.

Dimensions, stability and material

Measure the available space on your bedside table, desk or shelf before buying. A wide, heavy base can reduce the risk of tipping over. At the same time, the lampshade should not extend beyond the edge of the table. Metal, glass, plastic and acrylic all affect the weight, care requirements and lighting effect.

The following points are also useful in bedrooms and living rooms:

  • A shielded light source to reduce glare
  • Controls that are easy to reach
  • Sufficient distance from curtains and textiles
  • A dry, level surface
  • Cleaning with a soft, dry cloth

Which table lamp is right for each room?

  • Bedroom: Warm white light of around 2,400 to 3,000 Kelvin, easily accessible touch controls and a low overall height are practical.
  • Living room: A decorative table lamp can provide additional accent lighting. Pay attention to the shade shape, material and light distribution.
  • Home office: Multiple colour temperatures, sufficient lumens and a stable base make it easier to adjust the lighting to the task.
  • Shelf or hallway: Compact cordless models do not require a socket directly at the place where they are positioned.
  • Terrace or balcony: Only use models whose description explicitly permits dry outdoor use. Water and moisture warnings must be observed.

Table lamp FAQ

How many lumens should a table lamp have?

That depends on how it will be used. Lower brightness may be sufficient for decoration or a bedside table. For reading or working, luminous flux, the distance to the surface and the direction of the light are key. So compare the lumen rating rather than looking only at wattage.

Is an LED table lamp cheaper to run?

LEDs often require less electrical power than traditional light sources at a comparable brightness. However, running costs depend on wattage, daily usage and the electricity tariff. With rechargeable lamps, charging requirements also need to be considered.

How long does a rechargeable table lamp last?

The run time per charge depends on the battery capacity and brightness level. A figure such as ‘up to 160 hours’ refers to the lowest setting and cannot be equated with operation at full brightness. The product’s overall lifespan is also affected by charging cycles, proper storage and the manufacturer’s instructions.
