Choosing an LED lamp: practical buying tips for home, the office and gaming

An LED lamp may seem simple to choose, but product pages do not always highlight the information that matters for everyday use. A lamp may look attractive, yet prove impractical because of a cable that is too short, limited dimming options or a light colour that does not suit the room.

Three common pitfalls:

  • Looking only at appearance: an attractive LED table lamp may not provide enough light if you want to work with it.
  • Interpreting “dimmable” too broadly: some models only offer on/off control or three fixed settings, while others dim continuously.
  • Overlooking the power supply: a USB lamp, battery-powered lamp and plug-in lamp are not interchangeable in every location.

By checking the light output, colour temperature, controls and placement in advance, you can avoid making the wrong purchase.

Which specifications are important?

1. Light output: lumens tell you more than watts

Lumens (lm) indicate how much light a lamp produces according to the product specification. Watts mainly indicate electrical consumption. An LED lamp with a low wattage can therefore still provide a useful amount of light, but not every model is suitable for the same task.

As a guide:

  • Ambient lighting: a lower light output may be sufficient.
  • Reading or working: look for a focused light source and a higher lumen value.
  • Floor lighting: check whether the light spreads widely enough throughout the room.
  • Monitor lamp: pay attention to the mounting system, light distribution and compatible monitor thickness.

According to the product specification, the Brilliant Bow LED floor lamp provides 1300 lumens. This makes it more functional for a living room or work corner than a small decorative lamp. The stated energy efficiency class is F, and consumption is listed as 12 kWh per 1000 hours. Always check these details on the current product page.

2. Light colour: warm white or cooler task lighting?

Colour temperature is measured in kelvin (K). A lower value generally produces warmer light, while a higher value appears cooler and whiter.

  • Around 2700–3000 K: warm white light for a living room, bedroom or evening use.
  • Around 4000 K: more neutral light for a desk or general workspace.
  • Up to 6500 K: cooler light, where supported by the lamp.

An LED desk lamp with fixed warm white light is pleasant as ambient lighting, but less flexible if you also want to work with concentration. A model with CCT adjustment allows you to change the colour temperature. According to the product description, the Brilliant Bow models support a range of 3000 to 6500 K.

3. Dimming, power supply and safety

Check what “dimmable” means in practice. The Brilliant Helio LED table lamp has a three-step touch dimmer. This is different from a lamp with continuous dimming control.

Also pay attention to:

  • USB-A or USB power: convenient for a desk, laptop or games console, but you need a suitable port or adapter.
  • Battery: suitable for flexible placement, but check whether batteries are included.
  • Plug: practical for long-term use, provided there is a power socket nearby.
  • IP rating: IP20 models are intended for dry indoor spaces and not for bathrooms, balconies or outdoor use.
  • Integrated LED: on some lamps, the light source cannot be replaced. This is stated in the product specifications.

An energy efficiency class is not a direct indication of light quality. Always consider the lumens, wattage, usage time, controls and intended application together.

Frequently asked questions about LED lamps

How do I connect an LED lamp?

That depends on the model. Connect a lamp with a Europlug to a suitable power socket. A USB lamp works via a USB port or suitable adapter. A smart LED lamp generally needs to be connected to Wi-Fi and the accompanying app first. Only place IP20 models in dry indoor spaces.

How long does an LED lamp last?

Lifespan varies by product and usage conditions. Check the stated number of hours on the product page. On some models, the LED is integrated and cannot be replaced. If the lamp becomes less bright or stops working, it cannot then be renewed with a separate LED.

How much does an LED lamp cost to run?

Use the stated wattage and usage time to work this out. A 5 W lamp running for 1000 hours theoretically uses 5 kWh. Multiply this consumption by your current electricity tariff. Actual costs depend on the selected brightness, settings and number of hours the lamp is switched on.
