Choosing white lamps: practical buying tips for every room

White lamps suit many Dutch interiors, from a bright living room to a compact hallway or balcony. However, a white finish says little about light quality, energy consumption or whether a lamp is suitable for outdoor use. If you focus only on appearance and price, you could end up with a lamp that is too bright, turns out not to be dimmable or does not fit your socket.

So pay particular attention to these three common pitfalls:

  • A lamp appears to be dimmable, but the light source is not. With a fitting that takes a separate bulb, the bulb itself must be dimmable. For integrated LED lighting, check whether dimming works via a remote control, button or app.
  • An IP rating is interpreted too broadly. IP44 means protection against splashing water, not against immersion or powerful jets of water. A lamp with this rating is therefore not automatically suitable for an exposed spot in the garden.
  • Wattage is confused with brightness. Wattage indicates energy consumption; the number of lumens indicates how much light the lamp produces. A 5 W LED lamp can therefore provide plenty of light while using less energy than a traditional bulb.

Which specifications are important for white lamps?

1. Light colour and brightness

Colour temperature is expressed in kelvin (K):

  • 2200–2700 K: extra-warm or warm white light, suitable for a bedroom, seating area or evening lighting.
  • 3000 K: warm white light with a little more brightness, suitable for a living room, hallway or bathroom.
  • 4000 K: neutral white light, often comfortable above a desk, in a kitchen or for functional lighting.

Also check the number of lumens (lm). A small table lamp generally needs fewer lumens than a ceiling lamp intended to illuminate an entire living room. For example, the Brilliant Teranon ceiling lamp specifies 2300 lumens at 3000 K. The Aigostar E27 LED bulb produces 255 lumens at 4000 K, making it more suitable as supplementary lighting than as the only light source in a large room.

2. Socket and compatibility

Check the socket on your fitting before buying. Common types include:

  • E27 LED bulb: the larger screw fitting, often used in pendant lamps and table lamps.
  • E14 LED bulb: a smaller screw fitting for compact light fittings.
  • GU10 LED bulb: a push-and-twist fitting commonly found in spotlights and wall lamps.

For example, a white pendant lamp may have an E27 fitting, while a white outdoor wall lamp may require a GU10 bulb. The Aigostar retro pendant lamp uses an E27 bulb holder and, according to the product information, is supplied without a light source. The Philips Fylx outdoor wall lamp has a GU10 fitting, but the GU10 bulb must be chosen separately.

3. Outdoor use, bathrooms and damp areas

For outdoor use, the IP rating is a practical point to check. The Brilliant Viani has IP44 and is splash-proof according to its product specifications. This makes the white table lamp suitable for, for example, a balcony or covered terrace, but not for placing in water. The Philips Fylx also has IP44 and is designed as a white outdoor wall lamp.

For indoor lighting, IP20 is common. This is sufficient for dry rooms, but not for a location where the lamp may come into direct contact with splashing water. Also check whether the manufacturer expressly states that the lamp can be used in a bathroom, and follow the installation instructions.

Comparing energy consumption, dimming and smart features

For energy-efficient lighting, compare wattage with light output and check the energy label. A lower wattage does not automatically mean that a lamp will provide enough light in every situation. According to the product information, the Alecto SMARTLIGHT30 uses 5 W and produces 470 lumens. This smart white lamp works via Wi-Fi, can be dimmed in the app and offers adjustable white tones from 2000 to 4000 K. This model is not intended for outdoor use.

A dimmable lamp is particularly useful when one light point needs to serve several purposes. If you use a traditional dimmer, check that the light source and dimmer are compatible. With smart models, control is usually via an app, remote control or voice assistant.

Frequently asked questions about white lamps

Which light colour is best for a bedroom?

Many consumers choose warm white light between 2200 and 3000 K for a bedroom. This generally creates a softer atmosphere than 4000 K. Also consider the dimming function if you want to use the lamp at different times of day.

Are white lamps suitable for outdoor use?

That depends on the IP rating. A lamp with IP44 is resistant to splashing water and may be suitable for a balcony, terrace or sheltered outside wall. Always check the product description, and do not place the lamp in water or under a direct jet of water.

How much does an LED lamp cost to run each year?

You can calculate this yourself using: wattage ÷ 1000 × number of hours switched on × your electricity tariff. A 5 W lamp switched on for four hours a day uses approximately 7.3 kWh per year. The final cost depends on your energy tariff and actual usage.
