Lighting and lamps for your home: a guide to choosing practical and decorative lighting

The right lighting can make a room more practical, comfortable or flexible to use. But design and light colour aren’t the only things to consider when choosing lamps. Many disappointing purchases come down to unclear dimming information, unsuitable fittings or a lack of guidance on outdoor use.

Common pitfalls when buying lamps and lights

1. “Dimmable” doesn’t automatically mean compatible

An LED bulb may be labelled as dimmable but still flicker with a particular LED dimmer or only respond across a limited range. Before you buy, make sure the dimmer, bulb and minimum load are compatible. A conventional dimmer designed for halogen lamps won’t necessarily work with LEDs.

2. Decorative lighting is chosen for its appearance rather than where it will be used

Decorative indoor lighting isn’t automatically suitable for a balcony, patio or garden. For indoor and outdoor lighting, check the stated IP rating. For example, the Vivreal string lights are listed as IP65 rated. You should still check the connection, socket and installation instructions.

3. The fitting, wattage and what’s included are overlooked

A lamp with an E27 fitting is often supplied without a bulb. The maximum permitted wattage matters too. If a lamp is rated for a maximum of 10 or 40 watts, you mustn’t exceed that limit. So, before you buy, check:

  • Is a bulb included?
  • Which fitting do you need?
  • What’s the maximum permitted wattage?
  • How long is the cable?
  • Is a switch, foot switch or dimmer already built in?

Key features to consider

Dimming and electrical compatibility

When choosing an LED dimmer, three things need to match: the bulb type, power range and connection type. According to the product details, the Aigostar LED rotary dimmer is designed for 3–60 VA with dimmable LEDs and 7–110 VA with incandescent and halogen lamps. In Germany, an appropriately qualified electrician should install an in-wall switch.

A smart option may offer additional features. According to the product description, the Aigostar Smart Rotary Dimmer uses Bluetooth Mesh, supports brightness adjustment from 10 to 100 per cent and doesn’t require a separate hub. Before installation, check the switch type, existing wiring and compatibility with your bulb.

Fitting, brightness and light colour

E27 describes the base, not the brightness or light colour. You’ll also need to consider lumens, kelvins and the bulb shape:

  • Lumens indicate the amount of light.
  • Kelvins describe the colour temperature, such as warm white or neutral white.
  • The bulb shape must fit the lampshade and fitting.
  • For table and floor lamps, make sure the switch is within easy reach.

A floor lamp with two E27 fittings can change how light is distributed around the room. The Lameke Cone Shade Floor Lamp is listed as having two E27 fittings with pull switches and a maximum wattage of 40 watts per bulb. According to its description, it’s designed for indoor use.

Material, cable length and IP rating

For table and floor lamps, stability, cable routing and switch position are practical things to consider. With string lights, you should also check the cable length, connection options, whether the bulbs can be replaced and the IP rating.

According to the product details, the Vivreal G40 Decorative String Lights are 20 metres long and include 23 LED bulbs, which can be replaced. They’re listed as IP65 rated. The description says the string can be connected to other strings and used with a suitable dimmer. Even so, when installing lights outdoors, make sure the power supply and plug connections aren’t left exposed to water.

More practical tips for choosing

For flexible room lighting, it can be useful to combine several light sources:

  • A ceiling light provides general illumination.
  • A floor or table lamp adds light to reading and work areas.
  • A dimmable string of lights adds decorative accents.
  • A smart light switch lets you set schedules or scenes.
  • A foot switch makes freestanding lamps easier to operate.
  • A candle warmer lamp or plasma lamp works mainly as decorative accent lighting.

With a candle warmer lamp, follow the guidance on clearance and heat, as well as the manufacturer’s instructions. Decorative products shouldn’t be left running unattended for long periods, and should be kept out of reach of children and pets.

Frequently asked questions about home lighting and lamps

How much does it cost to run an LED bulb?

Running costs depend on the wattage, how long the bulb is used each day and the price of electricity. The simple calculation is: wattage divided by 1,000, multiplied by the number of hours in use and the price per kilowatt-hour. A 10-watt bulb uses 1 kWh over 100 hours of operation.

Can any LED bulb be used with an LED dimmer?

No. Both the bulb and dimmer need to be listed as compatible. The minimum load may also matter. Specifications such as “3–60 VA for dimmable LEDs” can help you narrow down your options, but you’ll still need to check that the specific combination will work.

What IP rating do you need for outdoor lighting?

That depends on where the light will be installed and how directly it will be exposed to the weather. A stated IP rating such as IP65 gives you a technical indication. The power supply, plug connection and wall connection must also be suitable for the intended outdoor location. Always follow the relevant manufacturer’s information and local installation regulations.
