Dimmable B22 LED Bulbs – Choosing High-Quality Drivers
The B22 (Bayonet Cap) is the most common bulb fitting in the UK. However, not all LEDs are created equal. To avoid flickering and buzzing, you need a dimmable bulb with a high-quality internal driver that can handle voltage fluctuations.
What makes a good LED bulb?
A premium 8W LED bulb replaces a 60W incandescent while providing better light quality. Look for these specs:
- Warm White (2700K): The ideal colour for UK living rooms and bedrooms.
- High-Quality Driver: The electronics in the base that prevent flickering when dimmed.
- Dimmable Range: High-end bulbs can dim down to 5% without cutting out.
Key Features to Look For
Buying the cheapest LED often leads to disappointment. Here is what to check on the box:
Where to Buy Quality B22 LEDs in the UK

Understanding the Specs
Don't be confused by technical jargon. Here is what matters for your UK home:
1. The B22 Fitting
This is the standard UK "push and twist" bayonet. Ensure the pins are clean and the bulb sits firmly in the lamp holder to prevent arcing.
2. Lumens vs Watts
In the LED world, ignore Watts for brightness. Look at Lumens. For a standard living room ceiling light, 806lm (roughly 8W-9W LED) is the direct equivalent of the old 60W glass bulb.
3. Colour Temperature
For a "warm" feel, choose 2700K. If you want a crisp, modern look (closer to daylight), look for 4000K. Avoid 6000K for homes as it can feel like a hospital or office.
4. Driver Quality
The "Driver" is a tiny computer in the bulb base. High-quality drivers can filter out "noise" on the electrical line, which is why a £6 bulb flickers less than a £2 bulb.
💡 Troubleshooting Dimmable Bulbs
- Flickering: Usually caused by an old Leading Edge dimmer. Swap to a Trailing Edge switch.
- Ghosting: If the bulb glows when off, it's caused by residual current in UK 2-way wiring.
- Humming: This is a sign the bulb driver is struggling with the dimmer's frequency. Try a different brand.
