Choosing LED lighting: a practical guide for indoors, outdoors and creating atmosphere

LED lighting is suitable for almost any space: from outdoor lighting and an outdoor wall light to an LED strip behind the television or an LED mirror in the bathroom. However, the cheapest option is not always the right one. An unsuitable IP rating, insufficient light output or an inconvenient power connection can make a product less useful than expected.

This guide helps you compare specifications and assess marketing claims realistically. That way, you can choose lighting for your home, balcony, garden, party venue or gaming space based on how you intend to use it and on verifiable product information.

Common pitfalls when choosing LED lighting

1. Confusing IP44 with waterproof

IP44 lighting is protected against solid objects larger than 1 millimetre and against splashing water from different directions. This does not mean that a lamp beneath a canopy will automatically withstand heavy rain, water jets or immersion.

IP44 may be suitable for a bathroom, balcony or sheltered exterior wall, depending on the installation location. Always check the instructions and do not install the lamp where water can collect directly on it. An LED strip with IP20 is intended exclusively for dry indoor spaces.

2. “Energy efficient” without considering wattage

LED lamps generally use little electricity, but actual consumption depends on wattage, operating time and the number of light points. So do not just look at the sales copy; also check the wattage and light output in lumens.

A 300-lumen lamp can be useful for orientation or ambient lighting, but may not provide enough light as the main source of illumination. With an LED string light, the focus is often more on decoration than on lighting an entire garden.

3. Buying ambient lighting for a purpose it was not designed for

Warm white light of around 2700–3000 kelvin usually creates a calm atmosphere. Cooler light can be more practical for workspaces, garages or certain bathroom activities. Colourful gaming lighting or an LED strip is suitable for creating ambience, but does not automatically replace a functional desk lamp.

Also consider the power supply. A solar outdoor lamp works without a mains connection, but needs direct sunlight to charge its battery. A plug-in string light will continue working as long as a suitable socket is available.

The key specifications explained

Light colour and light output

Colour temperature is expressed in kelvin:

  • 2700–3000 K: warm white, suitable for gardens, balconies, living rooms and ambient lighting.
  • 3000–4000 K: more neutral light for hallways, bathrooms or workspaces.
  • RGB or multicolour: decorative effects for a party venue, bedroom or gaming space.

Lumens indicate how much light a product emits according to its product specification. Only compare lumens between products intended for similar uses. For example, an outdoor wall light with a sensor does not necessarily need the same light output as a lamp that continuously illuminates a patio.

Protection against moisture

Before buying, check:

  1. The IP rating.
  2. Whether the product is intended for indoor use, outdoor use or both.
  3. Whether the power supply, adapter and connection points have the same level of protection.
  4. Whether the lamp may be exposed to direct water.

Many products in this selection are listed as IP44. This means protection against splashing water; it does not mean that the lamp can be placed underwater. An LED mirror with IP44 should be installed in the bathroom in accordance with the safety instructions and away from direct water jets.

Installation and power supply

An integrated LED is often easy to install, but if it develops a fault, it cannot be replaced separately. With a GU10 fitting, you can choose and replace a suitable light source yourself. Also consider:

  • Plug-in: constant power, but a socket and cable routing are required.
  • Battery: flexible to position, but the batteries need replacing.
  • Solar: no mains cable required, but the lighting duration depends on charging and conditions.
  • USB or USB-C: convenient for desks, wall decoration or gaming lighting.
  • Fixed connection: have installation on the mains carried out in accordance with the applicable regulations.

Frequently asked questions about LED lighting

How long does LED lighting last?

Lifespan varies depending on the product and conditions of use. Some manufacturers state a number of operating hours, but this is a product specification and not a guarantee that every individual item will function for exactly that long. Ventilation, moisture, switching frequency and the quality of the power supply or adapter all play a role.

How much does LED lighting cost to run?

The cost depends on the wattage, number of lamps, operating time and your electricity tariff. Multiply the power in kilowatts by the number of operating hours and your tariff per kilowatt-hour. Solar lighting does not use mains electricity while operating, but its performance depends on sunlight and battery capacity.

Can I install LED lighting myself?

A string light, USB lamp or magnetic lamp can often be installed without fixed wiring. For a fixed wall light connected to the mains, you must have the installation carried out in accordance with the applicable electrical regulations. For a bathroom lamp with LED, also check the IP rating, installation zone and instructions before you begin.
