Buying lamps without regrets: how to choose lighting for indoors and outdoors

A new lamp should not only look good. Its dimensions, fitting, power supply and protection against moisture determine whether your purchase will also be practical. If you focus only on colour or price, you may discover after installation that an E27 bulb does not fit, a wall light is unsuitable for rain or a table lamp does not provide enough light.

When buying lamps, these are the main pitfalls to watch out for:

• Confusing IP44 with waterproofing: IP44 lighting is protected against splashing water, but not against immersion or direct jets of water.
• Forgetting a light source: some lamps are supplied without a bulb. Check whether an LED bulb, E27 bulb, E14 bulb or GU10 bulb is included.
• Underestimating dimensions: a pendant light may hang too low because of a long cable, while a ceiling light with multiple light points can look too imposing in a small hallway.
• Treating marketing claims as guarantees: claims about lifespan, ambience or sustainability often come from the brand’s product information. Treat them as product specifications or brand claims, not as a guaranteed result in every home.

The most important specifications when buying lamps

1. Choose the right fitting and light source

The fitting determines which light source you can use. An E27 fitting is the familiar large screw fitting. An E14 fitting is narrower and is often found in compact table lamps, wall lights and decorative fittings. GU10 is widely used for spotlights.

Always check:

• the type of fitting;
• the maximum wattage;
• whether the bulb is included;
• whether the light source can be replaced;
• whether dimming is possible with the chosen bulb and dimmer.

A lamp with integrated LED does not have a separate fitting that the user can access. The LED light source in the Brilliant Iseo wall light is integrated. According to the product information, this lamp provides 300 lumens, warm white light at 3000 K and has a rechargeable battery. The light source cannot be replaced by the user. This can be convenient, but makes replacement more difficult if the LED develops a fault.

2. Pay attention to lumens, colour temperature and intended use

Wattage mainly indicates energy consumption, not the amount of light produced. For brightness, look at lumens:

• approximately 100 to 250 lumens: accent and ambient lighting;
• approximately 300 to 600 lumens: practical lighting for a hallway, balcony or small table;
• more lumens: suitable for larger areas or task lighting.

Colour temperature is expressed in Kelvin. Around 2700 to 3000 K generally produces warm white light that works well in a living room, bedroom or on a terrace. Neutral white light can be more practical for a workspace or utility room.

A solar table lamp depends on sunlight, so it will not necessarily operate for the same length of time or at the same brightness every evening. According to the product information, the Brilliant Viani can be charged using solar energy or USB, provides 170 lumens at 3000 K and has three dimming settings. This makes it suitable for flexible use on a balcony or terrace, although regular charging is still required.

3. Check the IP rating and installation requirements

For outdoor use, the IP rating is a practical selection criterion. IP44 lighting is splash-resistant and suitable for sheltered outdoor locations, such as a covered terrace, balcony or entrance. It is not the same as being fully waterproof. Do not place an IP44 outdoor lamp under a direct jet of water and never submerge it.

Also consider the installation:

• according to the product information, a fixed 230-volt outdoor lamp should be connected by a qualified electrician;
• a rechargeable lamp works without permanent wiring;
• a magnetic lamp must be securely attached to a flat, suitable surface;
• a freestanding lamp needs a stable base.

For example, the Atmosphera Zack Outdoor Floor Lamp is 108 cm high, runs on batteries and, according to the product description, has three light modes: multicolour, flame effect and white light. The lamp has an IP44 rating. Use it as flexible garden or terrace lighting, but protect it from situations where large amounts of water could reach the fitting for a prolonged period.

What does a lamp cost to run?

With LED lighting, energy consumption depends on the wattage and the number of hours it is switched on. A 4-watt lamp that runs for 1,000 hours uses approximately 4 kWh. Multiply this by your current electricity tariff to estimate the cost. For outdoor lighting, also check whether a battery or rechargeable battery needs to be recharged regularly. An integrated rechargeable battery can be practical, but its service life is limited over time and it cannot always be replaced.

Frequently asked questions about buying lamps

Which lamp do I need for outdoor use?

Choose a lamp with a suitable IP rating, such as IP44 for sheltered outdoor locations. Also check the installation, power supply and protection against direct rain. Professional installation is recommended for a fixed outdoor lamp.

What is the difference between an E27 and E14 bulb?

An E27 bulb has a large screw fitting, while an E14 bulb has a smaller fitting. They are not interchangeable. Check the fitting on the light fitting before buying a light source.

Is a solar table lamp always fully charged by the sun?

Not always. Charging time depends on the amount and intensity of sunlight, positioning and the battery. A model with a USB connection provides an additional charging option when there is little sunlight.
