Buying LED lighting for indoors and outdoors: how to choose the right lights and avoid costly mistakes

LED lighting for indoors and outdoors can make your living room feel cosier, your balcony more practical and your gaming setup more eye-catching. But not every light is suited to every space. A lamp that creates a lovely atmosphere in the bedroom can quickly get damaged outdoors, while a bright ceiling light won’t necessarily make for comfortable lighting during an evening on the sofa.

These tips will help you choose the right ambient lighting, functional light or decorative lighting for your needs.

Common pitfalls when choosing LED lighting

1. Mistaking IP44 for waterproof

An IP rating indicates how much protection a product offers against dust and moisture. IP44 generally means protection against splashes, not immersion or powerful jets of water. A light with IP44 may therefore be suitable for a sheltered balcony or terrace, but don’t place it in a puddle or directly beneath a rainwater drain.

Products with IP20 are designed for dry indoor spaces. An LED ceiling light with IP20, for example, shouldn’t be used in a bathroom area where it could be splashed directly.

2. Looking only at the number of LEDs

More LEDs don’t automatically mean more light or a better atmosphere. Also consider:

  • Luminous flux in lumens (lm): shows how much light the lamp produces.
  • Colour temperature in kelvin (K): around 2700–3000 K gives a warm white light; higher values look cooler.
  • Dimmability: check whether the light supports different settings, a dimmer or an app.
  • Light distribution: a wide beam works differently from focused accent lighting.

An LED string light with lots of small bulbs is mainly decorative. For reading, cooking or working, you’ll usually need a brighter light source.

3. Overlooking the power supply

A battery-powered light is flexible, but you’ll need to replace the batteries regularly. A rechargeable table lamp is more convenient if you move it often. A USB-rechargeable lamp is practical around the home, while a solar table lamp depends on getting enough daylight.

For each product, check:

  • how it charges or what type of battery it needs;
  • the cable or lead length;
  • whether it has a timer or memory function;
  • whether the light source can be replaced;
  • whether it needs to be installed.

Important specifications for indoors and outdoors

For the living room, bedroom and children’s room

For living spaces, colour, controls and size are often more important than maximum brightness. Warm white light around 3000 K, for example, suits a relaxing seating area or bedside table. A night light with a dimming function can be useful if you don’t want to switch on a bright light straight away.

For a desk or gaming setup, an LED string light or RGB lighting can work well as an extra touch. Choose a product that’s long enough and check how it’s controlled: with a button, remote control, Bluetooth or an app.

For balconies, gardens and party venues

Outdoor lighting needs to suit the conditions. Always check the IP rating, and don’t place a splash-resistant light somewhere it will be exposed to standing water for long periods.

For decoration, you could choose:

  • an LED string light with warm white light;
  • Christmas lights for indoors and outdoors;
  • a string light with several modes;
  • a solar table lamp;
  • a lamp with replaceable bulbs.

For longer strings, check the connections, maximum connectable length and safe distance from water. If the product has a mains plug, it’s important to use a suitable outdoor socket with protection.

Energy use and running costs

LED lighting usually uses less energy than traditional bulbs, but actual consumption depends on the wattage and how long the light is used. Here’s a simple calculation:

watts × hours of use ÷ 1000 = kilowatt-hours

A 2 W light left on for five hours a day uses significantly less energy than a 36 W ceiling light left on for the same amount of time. So, as well as lumens, check the wattage and how long you want the light to stay on.

Frequently asked questions about LED lighting for indoors and outdoors

Which LED lights can I use outdoors?

Choose a product with a suitable IP rating. IP44 is designed to protect against splashes and may be suitable for sheltered outdoor areas. IP20 is only suitable for dry indoor spaces. Always follow the manufacturer’s installation and safety instructions too.

How long does LED lighting last?

Lifespan varies depending on the product, LED module, power supply and conditions of use. For example, the product details for the Aigostar string lights state a lifespan of 15,000 hours. An integrated LED light source often can’t be replaced by the user, so check before buying.

How much does LED lighting cost to run?

This mainly depends on the wattage and how many hours the light is on. A 2 W light uses less energy per hour than a 36 W light. Use the formula wattage × hours of use ÷ 1000 to calculate consumption in kilowatt-hours. A timer or motion sensor can help reduce unnecessary hours of use.
