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.
Choosing the Right Colour Temperature
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.
Smart Lighting Compatibility
Many modern LED bulbs integrate easily with smart home systems, allowing you to automate your lighting using schedules, routines and voice commands.

Frequently Asked Questions
What is a 20W LED light equivalent to?
A 20W LED typically produces brightness comparable to a traditional 120–150W incandescent bulb, depending on its lumen output.
What LED bulb is equivalent to a 150-watt incandescent bulb?
Most LED bulbs producing around 2,000–2,600 lumens offer similar brightness to a 150W incandescent while using approximately 20–25W of electricity.
How many watts does an LED bulb use?
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.
Should I choose bulbs by watts or lumens?
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.
Can I replace fluorescent bulbs with LED 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.
What colour temperature is best for my home?
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.
Are LED bulbs worth upgrading to?
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.
