Choosing LED lighting: watch out for these specifications and pitfalls

LED lighting is energy-efficient, versatile and available for virtually every room. However, an attractive product photo does not guarantee that a lamp will suit your situation. The wrong fitting, light that is too cool or limited dimming functionality could leave your purchase unused.

With this practical checklist, you can compare LED lamps based on verifiable specifications. That way, you can find a suitable solution for the living room, bedroom, home office, balcony or garden.

Three common pitfalls with LED lighting

1. A fitting that does not fit

First, check the fitting on your light fitting. An E27 LED lamp has a large screw fitting, while an E14 LED lamp uses a smaller fitting. GU10 LED spotlights are generally twisted into place in a spotlight fitting. A lamp with the wrong fitting cannot be installed safely or practically.

Also pay attention to the voltage. A standard lamp for a Dutch light fitting usually operates at 220-240 V, but some standalone LED lamps or lamps with an adapter operate at low voltage.

2. Looking only at wattage

Wattage indicates how much power a lamp uses, not how much light you get. That is why you should look at lumens. Depending on its design, a 6 W lamp can have a very different light output from an 8 W lamp.

For a general comparison:

  • Lumens: the total amount of visible light.
  • Watts: energy consumption.
  • lm/W: the ratio between light output and power.
  • CRI: colour rendering. A CRI of 80 is a common value for general indoor lighting.

A higher light output is not automatically more pleasant. For a bedroom, soft, warm white light may be more suitable than a bright ceiling lamp.

3. Dimmable does not always mean compatible

A dimmable LED lamp must be suitable for the dimmer being used. Older dimmers designed for halogen or incandescent lamps can cause flickering, buzzing or a limited dimming range. Therefore, check the product information for both the lamp and the dimmer.

With smart lighting, dimming is often controlled via an app, remote control or smart home platform. This does not automatically mean that the lamp also works with a standard wall dimmer. For example, the Philips Hue Smart LED A67 states that it can be controlled via an app, remote control and wall switch, but also indicates that a standard non-dimmable dimmer is not suitable.

Which specifications are important?

Light colour: warm white or adjustable

Colour temperature is expressed in Kelvin:

  • 2700-3000 K: warm white light for relaxation and ambience.
  • 4000 K: more neutral light for working, reading or general lighting.
  • 6000-6500 K: cool white light for a bright, professional look.

A lamp with several colour temperatures is useful when one room serves different purposes. According to the product information, the VIVREAL LED floor lamp has settings of 3000 K, 4000 K and 6000 K. It is operated using a remote control within a stated range of up to 10 metres.

IP rating for balconies, patios or bathrooms

The IP rating indicates the extent to which a product is protected against solid particles and moisture. IP20 is intended for dry indoor areas. IP44 provides protection against splashing water, but does not mean that a lamp can be submerged or exposed to heavy rain for long periods.

A rechargeable lamp with an IP44 rating can therefore be practical on a sheltered balcony or patio. Do not place this type of product in a pond, in an unprotected garden or somewhere that water can remain directly on the housing.

Lifespan and replaceability

Pay attention to the stated lifespan in hours, but also check whether the light source is replaceable. With integrated LED lighting, the entire lamp usually needs to be replaced when the light source fails. With a light fitting featuring an E27, E14 or GU10 fitting, you can replace just the LED lamp.

A stated long lifespan is a manufacturer’s product specification, not a guarantee for every usage situation. Ventilation, switching behaviour, ambient temperature and the quality of the power supply can all affect service life.

Practical room-by-room guide

  • Living room: choose warm white light around 2700-3000 K for ambience. A dimmable floor lamp or smart E27 LED lamp gives you greater flexibility.
  • Bedroom: look for a low dimming setting and a soft colour temperature. A table lamp may be more practical beside the bed than a bright ceiling lamp.
  • Home office: more neutral light around 4000 K can be more comfortable for desk work. Check the lumen value and make sure the lamp does not reflect in your screen.
  • Balcony or patio: choose a rechargeable lamp with a suitable IP rating, such as IP44 for protection against splashing water. Protect the lamp from prolonged exposure to rain.
  • Kitchen or hallway: GU10 LED spotlights are suitable when you are using existing spotlight fittings. Check the cut-out size and fitting in advance.

Frequently asked questions about LED lighting

Is LED lighting cheaper to run?

LED lamps generally use less power than traditional light sources while providing a similar light output. To compare them, look at both wattage and lumen value. The actual saving depends on the number of hours the lamp is used, the electricity tariff and the type of lamp.

How long does an LED lamp last?

Lifespan varies from product to product. Some models, for example, state 15,000 or 25,000 hours. This is a manufacturer’s stated product specification. Good ventilation, a suitable power supply and correct use can help extend service life.

Can I dim every LED lamp?

No. Check that the packaging or product page explicitly states that the lamp is dimmable. With smart lighting, dimming may work via an app or remote control, while a traditional dimmer is not supported. Always check compatibility before connecting the lamp.
