Choosing LED lighting without a costly mistake: a practical guide for your home, garden and car

LED lighting can be energy-efficient, versatile and easy to replace. But a high lumen rating or modern look doesn’t tell you everything. A bulb might not fit your socket, may not be adequately protected outdoors, or could cause faults in your car. A few checks before you buy can help you avoid unnecessary returns and extra costs.

Common pitfalls when choosing LED lighting

1. Looking only at brightness

Lumens indicate how much light a bulb emits according to its product specification. More lumens don’t automatically mean more comfortable lighting. Cool, bright light might feel unwelcoming in a bedroom, while you’ll need good visibility on a driveway. So consider the light colour, how the light is distributed and where the bulb will go.

2. Overlooking the fitting and compatibility

A bulb with the wrong fitting won’t work, even if it looks a similar size. For indoor lighting, check whether you need a GU10 or G9 fitting, for example. H4 and 9005/HB3 are different connections for cars. LED car bulbs can also trigger vehicle warnings or flicker, and may require a CANbus decoder.

3. Treating outdoor lighting as if it were waterproof

An IP44 rating means protection against solid objects and splashing water. This makes a fitting suitable for many sheltered outdoor settings, but not for immersion or exposure to a powerful jet of water. Position IP44 outdoor lighting carefully and use a suitable outdoor socket.

Three things you should always check

Light colour: warm white or 6000K cool white

Colour temperature is measured in kelvin:

  • 2700K: warm white light with a soft, cosy feel.
  • 3000K to 4000K: more neutral light for hallways, workspaces and general lighting.
  • 6000K cool white light: appears whiter and brighter, and is often used for car lighting and functional outdoor lighting.

Warm light often works better with the furniture and textiles in a living room or dining room. A ceiling light for a living room or ambient lighting for a dining room doesn’t need to be the same colour as a headlight.

Fitting, dimensions and installation

Before you buy, check:

  1. The fitting type, such as G9, GU10, H4 or 9005/HB3.
  2. The space available in the light fitting or headlight housing.
  3. The voltage, for example 230 V for an outdoor fitting.
  4. Whether it can be installed without modifications.

For plug-and-play car lighting, this usually means the plug fits straight into the existing connection. Even so, check your vehicle’s documentation and the relevant legal requirements. A bulb that physically fits isn’t automatically approved for every type of use on public roads.

Protection, heat and lifespan

LEDs produce less heat at the light source than many traditional bulbs, but the electronics still need to dissipate heat. For car bulbs, look for an aluminium housing, fan or other cooling system if this is mentioned in the product specifications.

Lifespan claims depend on use, temperature, installation and power supply. So treat a stated lifespan of 15,000 or 50,000 hours as a product specification, not a guarantee that the bulb will last for exactly that long.

Frequently asked questions about LED lighting

How long does LED lighting last?

Lifespan varies by bulb and usage conditions. Manufacturers often state a number of operating hours, but heat, moisture, voltage fluctuations and daily use all affect how long a bulb actually lasts. So alongside the stated lifespan, check the warranty, fitting and conditions the bulb is designed for.

Is 6000K suitable for every room?

No. 6000K cool white light is best suited to functional uses, such as vehicle lighting, garages or certain outdoor spaces. Many households prefer 2700K to 3000K for a living room, bedroom or dining room, as it gives a warmer feel.

Does LED lighting use less electricity?

LED bulbs generally have a lower wattage than traditional light sources for a comparable use. Exact electricity consumption depends on the wattage and the number of hours the bulb is on. To estimate running costs, multiply the power in kilowatts by the number of hours used and your electricity tariff.
