Choosing an LED Lamp: A Practical Buying Guide for Every Room

An LED lamp can easily brighten a dark hallway, kitchen cupboard or child's bedroom. Yet not every lamp is suitable for every spot. A nightlight that feels pleasant beside the bed, for example, gives too little light for a worktop. A cordless lamp for the balcony also needs to be judged differently from a USB lamp for indoors.

Before you buy, watch out for three common pitfalls:

  • Too little information about brightness: a product may be described as “bright” without mentioning lumens. As a result, the lamp can turn out to be less useful in a cupboard or hallway than you expected.
  • Confusion between dimmability and colour choice: a lamp with three colour temperatures is not automatically dimmable. Check whether the brightness can be adjusted separately.
  • Incorrect placement: a lamp with a motion sensor does not always work well behind a door, in a full cupboard or in a spot where pets keep triggering the sensor.

Which specifications matter?

1. Brightness and colour temperature

Brightness is usually expressed in lumens (lm). For ambient lighting or an LED nightlight, a soft light output is often sufficient. For a kitchen worktop, wardrobe or staircase, you need more functional light.

Also pay attention to the colour temperature:

  • 2,800–3,200 K: warm light for a bedroom, children's room lighting or ambient lighting.
  • 4,500–5,000 K: neutral daylight for general lighting.
  • 6,500–7,000 K: cool white light for a cupboard, workspace or practical task lighting.

A product with multiple settings gives you more flexibility, but check whether the lamp also has a memory function or dimming mode.

2. Power, battery and charging

A rechargeable lamp with a USB connection is handy when there is no plug socket nearby. Look at the battery capacity in mAh, but bear in mind that the run time also depends on the brightness level you choose.

A battery-operated lamp can be positioned quickly, but check:

  • which battery type is needed;
  • whether batteries are included;
  • how easily the battery compartment closes;
  • whether the lamp is intended for continuous use or occasional lighting.

For children's room lighting, small parts and loose batteries are extra points to consider. Always follow the manufacturer's warnings and age recommendations.

3. Sensor, mounting and moisture protection

A lamp with a motion sensor can be practical in a hallway, toilet, wardrobe or under a kitchen cupboard. Check the detection range and the mounting method. A PIR sensor with a range of 3 to 5 metres can be suitable for a short passageway, but its performance depends on the placement and the movement in the room.

For outdoor use, an IP rating is important. IP44 in practice means protection against splashing water, but not against immersion or prolonged exposure to heavy rain. So place such a lamp in a sheltered spot on a balcony, patio or under a canopy.

Frequently asked questions about an LED lamp

How long does an LED lamp last?

The lifespan varies by model and depends on factors such as heat generation, usage time and the quality of the electronic components. An integrated LED module cannot always be replaced separately. So check whether the lamp has a replaceable light source and keep your purchase information safe.

Does an LED lamp use little electricity?

LED lighting generally uses low power, but the actual consumption depends on the wattage and the number of hours it is on. A 1 W lamp that runs for a few hours each day uses less than a more powerful fixture that stays on for long periods. With rechargeable models, the charging frequency and battery capacity also play a role.

Where should you place a lamp with a motion sensor?

Position the sensor in a spot where the desired movement is clearly visible, for example on the inside of a cupboard or along a hallway. Avoid obstacles such as doors, boxes or thick shelves. After installation, test whether the lamp does not turn on unnecessarily due to movements from pets or traffic outside the room.
