Buying LED lighting: a guide for living spaces, smart homes and creative projects

LED lighting can provide practical illumination, add decorative touches with RGB LED lights, or create more even lighting for photos and videos. The choice ranges from smart LED bulbs and LED strips to portable LED video lights. But it’s not just the number of colours or the advertised brightness that matters: you need to choose lighting that’s right for where you’ll use it.

Common pitfalls when buying LED lighting

1. Confusing lumens, watts and marketing claims

Power consumption in watts tells you how much electricity a light uses, not directly how bright it is. For brightness, look at the luminous flux in lumens. For example, a smart GU10 bulb rated at 4.9 W and 420 lm is suitable for directional lighting in a fitting, but won’t necessarily replace lighting designed to illuminate a whole room.

The claim ‘equivalent to 40 W’ is also just a comparison with traditional light bulbs. To choose the right light, consider lumens, beam angle and room size together.

2. RGB doesn’t replace good white task lighting

RGB colours work well for decorative scenes, gaming setups or ambient lighting. For reading, working and judging product colours, however, adjustable white tones and reliable colour rendering are more important. A dimmable LED bulb with a colour temperature of 2,700 to 6,500 K offers more flexibility than a model that only produces coloured effects.

For photos and video, the CRI rating may also be relevant. A higher rating indicates more natural colour rendering under the specified test conditions. Don’t take the manufacturer’s rating as evidence of a medical benefit or a guarantee of better results.

3. Overlooking the IP rating and installation location

IP20 is intended for dry indoor spaces only. An LED wall light or LED strip for a bathroom, kitchen or balcony needs an IP rating suited to its installation location. IP44, for example, means protection against splashing water, but not immersion.

With self-adhesive strips, you’ll also need to consider the surface, heat dissipation and where to position the power supply. An unsuitable surface or covered adaptor can cause problems with adhesion and safety.

Key things to check before you buy

Colour temperature and dimming

Colour temperature is measured in kelvins:

  • 2,700 to 3,000 K: warm white, often used in living rooms and bedrooms
  • 4,000 to 4,500 K: neutral white, suitable for workspaces
  • 6,000 to 6,500 K: cool white to daylight-like

Stepless dimming lets you fine-tune the brightness, rather than choosing from just a few fixed levels. If you’re buying a clip-on reading light or monitor light, check whether you can control it directly on the device and whether it can be attached securely.

Controls and smart home compatibility

A Wi-Fi LED bulb can often be controlled via an app, schedule or voice assistant. Before you buy, check whether you need a gateway and whether the bulb works with your network. Many products require 2.4 GHz Wi-Fi.

Matter-compatible lighting can make it easier to connect lights to different smart home systems. Even so, check which platforms are actually supported. According to the product details, the Hama Smart GU10 bulb is compatible with Matter, Alexa, Google Assistant and Apple HomeKit, and doesn’t require an additional gateway.

Power supply and portability

For a cordless LED light, check the battery capacity, charging port and realistic battery life. Video and photography lights may also offer mounting options such as a 1/4-inch thread, magnetic mount or cold shoe adaptor. A mains-powered photography light may be more practical for longer shoots, as you won’t need to stop to recharge it.

Frequently asked questions about LED lighting

How much electricity does LED lighting use?

Consumption depends on the power rating in watts and how many hours a day the light is on. A 5 W light running for ten hours uses 0.05 kWh. For a realistic estimate, also take into account power supplies, standby consumption and the brightness setting you actually use.

How long does an LED bulb last?

Lifespan is often given in operating hours, but it depends on temperature, usage and the electronics. Replacing a light with an integrated LED can be more involved than changing a GU10 or E27 bulb. Check whether the bulb can be replaced and what warranty or manufacturer information is available.

Which is better for a home office: a monitor light or a desk lamp?

A monitor light saves desk space and can direct light onto your work surface. A desk lamp usually gives you more freedom to position the light. The key things to consider are monitor width, how securely the light clamps on, colour temperature and whether you can avoid reflections on the screen.
