Choosing an LED lamp: a practical buying guide for every room

An LED lamp can provide practical lighting for a dark wardrobe, workspace or bedroom while also creating a pleasant atmosphere. However, the range of options is not always easy to compare. Terms such as “wireless”, “sensor” and “long battery life” only tell you something when you also look at the underlying specifications.

The following pitfalls are common:

  • A rechargeable lamp without clear charging details: check whether it uses USB-A, USB-C or another connection, and whether the battery capacity is stated.
  • A motion sensor that is unsuitable for the space: a PIR sensor works within a specific range. For the cabinet lights below, that range is stated as 3 to 5 metres in the product information.
  • A decorative lamp being used as the main light: a Star Wars lamp or RGB lamp can create a lovely atmosphere, but a low lumen output is not intended to brightly illuminate an entire room.
  • Not considering moisture resistance: a lamp with IP20 should be used indoors and in dry conditions. For a balcony or patio, you need a suitable IP rating.

Which specifications are important?

1. Brightness and light colour

Brightness is measured in lumens. An LED desk lamp producing 210 lumens is suitable for a desk, bedside table or accent lighting. For a cupboard, worktop or workspace, focused and bright light is often more useful.

Also pay attention to the colour temperature, measured in kelvin:

  • 2,800–3,200K: warm white, suitable for ambient lighting and bedrooms.
  • 4,500–5,000K: more neutral light for everyday use.
  • 6,500–7,000K: cool white light for a clearly lit cupboard or workspace.

A lamp with several colour temperatures is practical when the same lamp is used in different locations.

2. Power supply: battery or rechargeable

A battery-powered lamp is quick to install, even when there is no socket nearby. The downside is that you have to replace the batteries. Also check whether batteries are included. The Minecraft Logo LED Light, for example, requires 3 AAA batteries, which are not included according to the product information.

A USB rechargeable lamp is more convenient for regular use. Check the battery capacity, charging voltage and included cable. The 30 and 40 cm sensor cabinet lights use a built-in 1,100 mAh battery and charge via 5V USB with a 0.5A charging current.

3. Positioning and protection

A wireless lamp can be placed wherever you need it or mounted using the supplied materials. Measure the available space beforehand. The ultra-thin cabinet lights are 30 or 40 cm long respectively and 3.8 cm wide. This makes them suitable for cupboards, shelves and narrow wall spaces.

The IP rating is important for outdoor use. The Brilliant Aro has IP44 and, according to the product information, is suitable for use on a balcony, patio or in the garden, but not for immersion or severe weather. An IP20 lamp, such as the Helio table lamp, is intended for dry indoor spaces.

Frequently asked questions about LED lamps

How do I install a wireless LED lamp?

Place a table lamp on a stable, level surface. For cabinet lighting, use the supplied tape or mounting materials and first check that the surface is clean and dry. Mount a wall lamp according to the instructions and use only the specified batteries or USB power supply.

How long does an LED lamp last?

Lifespan varies depending on the model, frequency of use and battery. An integrated LED light source cannot always be replaced. Therefore, check whether the manufacturer states a lifespan and, for a rechargeable lamp, also pay attention to the battery specifications. “Long battery life” without a measurable operating time is not a useful basis for comparison.

How much does it cost to use an LED lamp?

Consumption depends on the wattage and number of hours the lamp is switched on. A 1W lamp uses approximately 1 kWh over 1,000 hours of use; a 2W lamp uses approximately 2 kWh. With battery-powered models, you also need to factor in the cost of replacement batteries or charging. So do not look only at the purchase price, but also consider the chosen power supply and expected usage.
