Choosing LED lighting: look out for these specifications and pitfalls

LED lighting is suitable for almost any space: from an LED strip behind the television to a string of LED lights on the balcony. However, an attractive product photo says little about practical usability. Length, power supply, IP rating and controls determine whether the lighting is suitable for your home, garden or event.

This buying guide helps you compare mood lighting, decorative lighting, smart lighting and RGB LED lighting using verifiable product information. That way, you can avoid a disappointing purchase and make a more informed choice.

Common pitfalls when choosing LED lighting

1. An attractive light colour without the right application

Warm white LED lighting around 2700K to 3000K generally creates a softer look than cool white light. This works well in a living room, bedroom, dining area or festive decoration. For task lighting, a different colour temperature may be more practical.

Also consider the difference between a single fixed light colour and adjustable lighting. A string of warm white lights creates a calm atmosphere, while RGB LED lighting can display multiple colours and effects. This does not automatically mean that the light output is suitable for use as the main lighting.

2. “For indoor and outdoor use” without considering IP protection

An outdoor product must be able to withstand the conditions in which you intend to use it. The IP rating indicates how well a product is protected against dust and moisture.

  • IP20: intended for dry indoor spaces.
  • IP44: protected against splashing water, but not against immersion.
  • Also check whether the adapter, plug and controls are suitable for outdoor use.
  • Do not place lighting in standing water and always follow the safety instructions.

According to the product description, the M.TK Lamp Beads Strip Light measuring 14.7 metres has an IP44 rating. The 4.3-metre version has the same stated rating. Both models run on three AA batteries, which are not included.

3. Not paying enough attention to length, connections and installation

An LED strip or string of lights can look more spacious in photos than it really is. Measure the following beforehand:

  1. The length of the surface you want to illuminate.
  2. The distance to the socket.
  3. The space required for an adapter, battery compartment or controls.
  4. How you want to attach the lighting.

According to the product information, a Philips Hue LED strip can be cut at designated points. Always check where these cutting points are; shortening the strip elsewhere may affect its operation. With a string of lights, the illuminated length is particularly important. The Atmosphera LED Garland is 435 cm long, of which 385 cm is illuminated and 50 cm consists of the connecting cable.

Important specifications to compare

Light colour, brightness and functions

The following details are relevant for decorative lighting:

  • Kelvin (K): the colour temperature. 3000K is generally described as warm white.
  • Lumens (lm): the amount of light. The Philips Hue Flux LED strip specifies a maximum of 1200 lumens.
  • Dimmability: useful when you want to switch between soft mood lighting and greater visibility.
  • Light modes: some battery-powered products offer several flashing or transition programmes.
  • CRI: particularly relevant for lamps that need to reproduce colours accurately. The Ulanzi VL119 specifies a CRI of 95, according to Ulanzi’s product specifications.

According to Philips’ own product information, the Hue Essential LED strips support control via the Hue app, voice control and Matter. Before buying, check that your smart home platform is actually compatible and whether a bridge is required for the functions you want to use.

Power supply and running costs

Battery-powered lighting is useful in places without a socket, but you need to allow for replacing or recharging the batteries. Mains power is more practical for long-term use, such as at an event or for permanent indoor lighting.

The Aigostar WiFi WB Smart Filament Bulb has an E14 fitting, a stated luminous flux of 470 lumens and works indoors via Wi-Fi and Bluetooth. The lamp has an energy efficiency rating of F. So, do not compare only the purchase price; also consider the wattage and how long the lamp is switched on each day.

Safety and warranty

Use LED lighting according to its stated application. A product with IP20 should not be used outdoors or in a damp room. With rechargeable products, the cable and connection must not get wet. The Ulanzi VL119 has a built-in lithium battery; according to the safety information, it must not be pierced, dismantled or exposed to high heat.

Many of the products mentioned are covered by a minimum two-year legal guarantee under EU consumer law. Some models also specify an additional manufacturer’s warranty, such as one year for the M.TK string lights. Keep your purchase details and check the terms and conditions for the product concerned.

Frequently asked questions about LED lighting

How do you install an LED strip without damaging the wall?

Clean the surface first and use only the supplied or suitable mounting materials. Do not place the strip directly next to a heat source. With cuttable strips, you may only shorten them at the indicated cutting points. Leave the power supply unobstructed for ventilation and switch off the power before cleaning the strip.

How long does LED lighting last?

The lifespan varies according to the model, usage time, heat dissipation and the quality of the power supply. The Philips Hue Flux specifies a lifespan of 25,000 hours for its light sources; the Aigostar lamp specifies 15,000 hours. These are the brands’ product specifications and do not guarantee the same performance in every situation.

Does LED lighting use a lot of electricity?

LEDs generally use little power compared with traditional light sources, but actual consumption depends on wattage, brightness, the number of lamps and operating hours. So, check the stated wattage and choose a timer or dimming function when the lighting does not need to run continuously at full brightness.
