Choosing lamps and lighting: how to avoid unsuitable purchases indoors and outdoors

Buying a new lamp seems simple until you discover that the fitting does not fit, the light is too bright or an outdoor lamp does not offer sufficient protection against moisture. With lamps and lighting, it is therefore not just about design. The right choice depends on the fitting, light output, colour temperature, dimensions and where you want to use the lamp.

Three common pitfalls are:

  • A decorative lamp without a suitable light source: some table lamps, pendant lamps and wall lamps are supplied without an LED bulb. Check in advance whether you need an E27, E14 or GU10 light source.
  • Confusing wattage with brightness: with LED bulbs, the wattage mainly indicates energy consumption. Look at lumens for light output. For example, according to the product specification, a 4.9 W LED bulb can provide 470 lumens.
  • Using an indoor lamp outdoors: a lamp with IP20 is intended for dry indoor areas. A suitable IP rating is needed for a balcony, patio or exterior wall. IP44 outdoor lighting is splash-resistant, but is not automatically suitable for direct jets of water or immersion.

The most important parameters when choosing lamps and lighting

1. Check the fitting and dimensions

The fitting determines whether a light source will fit your lamp. The most common types are:

  • E27: a large screw fitting, widely used in table lamps, floor lamps and pendant lamps.
  • E14: a smaller screw fitting, often used in compact fittings and chandeliers.
  • GU10: a push-and-twist fitting for spotlights, such as ceiling spotlights and outdoor wall lamps.

Also pay attention to the lamp’s shape and height. A large G95 bulb with a diameter of 9.5 cm will not fit every lamp. For a pendant lamp above the dining table, the overall height, adjustable cable and diameter are also important.

2. Look at lumens and colour temperature

Lumens indicate how much light a lamp emits. A few hundred lumens are often enough for atmospheric lighting. For functional lighting, such as above a workspace, a higher light output is more appropriate.

Colour temperature is measured in kelvin:

  • 2,200–2,700 K: extra warm to warm white, suitable for a relaxed atmosphere.
  • 3,000 K: warm white with slightly more brightness, suitable for living areas, hallways and outdoor spaces.
  • Higher values generally create a more neutral or cooler effect.

According to the product information, a Philips E14 globe-shaped LED bulb has a colour temperature of 2,700 K, 470 lumens and a consumption of 4.9 W per light point. The Philips E27 bulbs with a 40 W equivalent also have 2,700 K and 470 lumens. Always check that the atmosphere you want matches the space.

3. Assess energy consumption, dimmability and service life

LED bulbs are generally a practical choice for energy-efficient lighting. According to Philips’ own information, the LED bulbs mentioned use around 80% less energy than comparable incandescent bulbs. This is a claim made by the brand; the actual saving depends on usage time, light output and the bulb being replaced.

Pay attention to the following details:

  • Wattage: the electrical consumption of the light source.
  • Lumens: the amount of light emitted.
  • Energy label: the current EU scale may differ from older labels.
  • Dimmability: not every LED bulb works with a dimmer.
  • Service life: Philips states 15,000 operating hours for various models. This is the manufacturer’s specification and is not a guarantee of exact performance in every situation.

Outdoor lighting: IP44 does not mean waterproof

For outdoor wall lamps, garden lighting and balcony lamps, the IP rating is an important point to check. The first digit refers to solid particles and the second to water.

A fitting with IP44 is protected against splashing water from different directions. Install this type of lamp according to the instructions, for example beneath a canopy or on a sheltered exterior wall. An IP44 lamp is not intended to stand underwater or to be exposed to direct jets of water for extended periods.

Solar lamps are useful when you do not want to run a cable. However, pay attention to the position of the solar panel. Shade from a wall, balcony edge or tree can affect charging time. A model with USB charging provides a practical back-up in these circumstances.

Frequently asked questions about lamps and lighting

Which fitting do I need for my lamp?

Check the old light source or the fitting’s product specifications. E27 is a large screw fitting, E14 is a small screw fitting and GU10 is a fitting for spotlights. Also check the maximum wattage, dimensions and whether the light source needs to be dimmable.

How much does LED lighting cost to run?

This depends on the wattage and the number of operating hours. A 4.9 W LED bulb uses less electricity per hour than a traditional 40 W bulb. Calculate the exact cost using: wattage ÷ 1,000 × operating hours × your electricity tariff. Use lumens to compare light output, rather than wattage alone.

How long do LED bulbs last?

The product information for several of the Philips models mentioned states 15,000 operating hours. This is the manufacturer’s specification. Actual service life can be affected by heat, ventilation, switching frequency and the quality of the fitting. Always switch off the power before replacing an LED bulb and follow the manufacturer’s instructions.
