How many watts does an LED bulb use?
As a general guide, LED bulbs should be chosen by lumens (brightness) rather than wattage. For example, an LED producing around 2,000–2,600 lumens is often comparable to a traditional 150W incandescent bulb while using only a fraction of the electricity.
Benefits of LED bulbs include:
Lower electricity bills
Long operating life
Instant full brightness
Minimal heat output
Reduced maintenance
Environmentally friendly performance
Upgrade your existing light fittings with smart LED bulbs that offer greater flexibility and convenience.
Popular smart bulb features include:
Wi-Fi connectivity
Remote control via smartphone
Timer scheduling
Voice assistant compatibility
Adjustable brightness
Warm and cool white settings
RGB colour changing
Energy monitoring (selected models)
If you're looking for an E27 lightbulb that you can connect to Wi-Fi and set a time, smart LED bulbs make it easy to automate your home's lighting without replacing your existing light fitting.
Finding the correct replacement bulb is important for maintaining the performance of your lighting fixture.
Our collection may include replacement options for popular lamp types such as:
Philips GR10Q 4-pin 2D compact fluorescent light bulbs
Fusion B28 28W GR10Q 4-pin non-dimmable lamps
LED replacement bulbs
Decorative filament bulbs
Smart LED bulbs
Energy-saving compact fluorescent replacements
Whether you're replacing older fluorescent lamps or upgrading to modern LED alternatives, choosing the correct fitting, brightness and colour temperature ensures the best results.
Colour temperature affects how a room feels and functions.
Common options include:
Warm White (2700K–3000K)
Ideal for bedrooms, lounges and dining rooms where a cosy atmosphere is preferred.
Neutral White (4000K)
A balanced option for kitchens, bathrooms and home offices.
Cool White / Daylight (5000K–6500K)
Suitable for garages, workshops, utility rooms and task lighting where maximum visibility is important.
Many homeowners also look for high colour rendering (CRI) LED bulbs to provide more natural-looking colours indoors.
Many modern LED bulbs integrate easily with smart home systems, allowing you to automate your lighting using schedules, routines and voice commands.
Smart bulbs can help you:
Turn lights on before you arrive home
Create bedtime routines
Set wake-up lighting schedules
Dim lights for movie nights
Change colours for parties

A 20W LED typically produces brightness comparable to a traditional 120–150W incandescent bulb, depending on its lumen output.
Most LED bulbs producing around 2,000–2,600 lumens offer similar brightness to a 150W incandescent while using approximately 20–25W of electricity.
LED bulbs are highly energy efficient. Common household models use between 4W and 15W, while brighter bulbs may use 20W or more depending on the required light output.
Lumens measure brightness, while watts measure electricity consumption. When buying LED bulbs, comparing lumen ratings is the best way to match the brightness of older incandescent bulbs.
In many cases, yes. However, it's important to check the fitting type, size and compatibility before replacing specialist fluorescent lamps such as GR10Q or 2D bulbs.
Warm white is ideal for relaxing spaces like bedrooms and lounges, neutral white works well in kitchens and bathrooms, while cool white or daylight is best for task lighting and workspaces.
Yes. LED bulbs last significantly longer than traditional bulbs, use much less electricity, require less maintenance and provide excellent light quality, making them one of the most cost-effective lighting upgrades for any home.
