LED lighting is available as a standalone light source, ceiling light, table lamp and smart lamp. With such a wide range, comparing your options isn't always straightforward. A lamp might look lovely and atmospheric, yet still not provide enough light for a workspace. Or a smart LED bulb might not work with a standard dimmer, or a large filament bulb might not fit in your light fitting.
With this practical guide, you'll know exactly which specifications really matter in a British home.
Wattage tells you how much electricity a lamp uses, but not how much light you get. For that, you need to look at lumens. A 4 W LED bulb might deliver 360 lumens, while another lamp with a similar wattage could have a completely different light output.
Use wattage mainly to compare energy consumption. Use lumens to decide whether the lamp is suitable for the room.
An E27 LED bulb has a large screw fitting, and an E14 LED bulb has a smaller one. Also check the diameter and height. A decorative G125 filament bulb might look attractive, but it may not fit inside a small enclosed light fitting.
Pay attention to the fitting itself, too. Some LED bulbs cannot be used in a fully enclosed fitting due to heat build-up. Always follow the manufacturer's safety instructions for this.
With a traditional dimmer, the bulb must be explicitly marked as dimmable. Some smart LED bulbs are only dimmed via an app, remote control or voice assistant. For example, a Nedis SmartLife E14 bulb states that dimming is done through the app or voice assistant, not via a traditional dimmer.
So check before you buy:
For mood lighting in a bedroom or living room, a low light output can be pleasant. A filament LED bulb of 250 lumens, such as the Nedis LED Filament Bulb E27, is mainly intended as a decorative light source. For a desk, kitchen or general ceiling lighting, you'll usually need more light.
An LED ceiling light with 2,000 to 2,400 lumens is better suited as the main lighting in a room. Also consider the size of the room, the colour of the walls and ceilings, and whether there are other light points.
Colour temperature is measured in kelvin (K):
A filament bulb at 2,100 K gives a distinctly warm glow. A smart lamp with a range of 1,800 to 6,500 K offers more flexibility – warm light in the evening and cooler light while you're working.
Check the fitting before you order a lamp. A standard E27 or E14 fitting makes physical installation straightforward: switch off the power, screw the bulb in, and don't overtighten it.
For smart home lighting, the connection and control method are also important. Check whether the lamp works with:
A Philips Hue bulb, for example, can be controlled via Bluetooth; for more advanced features such as timers, automations and control when you're out, the product information states that a Hue Bridge is required.
Why this fits the profile: This decorative E27 LED bulb simply screws into an existing fitting and has a stated low consumption of 3.8 W. The 2100 K colour temperature is ideal for mood lighting.
The product details list both lumens, wattage, fitting and colour temperature. So you don't have to rely solely on the retro look.
250 lumens, dimmable according to the product information, E27 fitting and glass housing.
Why this fits the profile: Ideal for households that want to control multiple lamps centrally. According to the product description, control works via Bluetooth, the Hue app and compatible voice assistants.
Control isn't limited to a traditional dimmer. The product information clearly distinguishes between Bluetooth control and additional Hue Bridge features.
E27 fitting, dimmable, 1,100 lumens per light point and a stated lifespan of 25,000 hours.
Why this fits the profile: This LED ceiling light is designed as general lighting and comes with a remote control. According to the product details, the colour temperature ranges from 2700 to 6500 K.
The lamp uses an integrated light source and its own remote control. This means no separate LED bulb or external dimmer is needed, but installation must be carried out in accordance with local regulations.
2,400 lumens, dimming function, adjustable colour temperature and a round diameter of 30 cm.
Why this fits the profile: This LED table lamp is ideal for reading, working or directed light. The lamp head is adjustable and the telescopic arm can be adjusted in height.
The product specifications list light output, colour temperature, cable length, IP20 rating and adjustability. So you know in advance that this lamp is for indoor use.
650 lumens, 2700 K warm white light, adjustable lamp head and height-adjustable arm.
We've put together a full, up-to-date list of products that fully meet these strict selection criteria and comply with current European safety regulations.
Switch off the power before removing or fitting a lamp. Screw a loose bulb in straight and without using excessive force. Do not use a lamp if the glass is damaged. With integrated LED ceiling lights, pay attention to the fixing, ventilation and connection. If you're unsure about electrical wiring, it's wise to get help from a qualified electrician.
A lamp with IP20 is intended for dry indoor spaces. For the bathroom, balcony or other damp areas, you must check the required IP rating of the fitting.
That depends on the floor area and the number of light points. A decorative lamp of 250 to 550 lumens works mainly as mood lighting. For general lighting, a ceiling light of around 2,000 lumens or more is usually more practical. Several smaller lamps often give a more even result than one very bright light source.
Not automatically. Some smart bulbs are only dimmed via an app, remote control or voice assistant. Check the product information and don't use a traditional dimmer if it's specifically advised against.
The stated lifespan varies by model. The product details for the lamps mentioned show values from 15,000 to 25,000 hours. Actual usage time can be affected by heat, switching frequency, ventilation and the quality of the fitting. An integrated LED light source usually cannot be replaced separately; if it fails, the entire lamp must be replaced.
